BS First only Enterprise PCs and Servers were affected unless someone bought Crowdstrike. Second, only a fraction of devices with Crowdstrike were affected. I work for a major nonprofit Hospital and about 25% of our servers were affected. I spent 11 hours manually remediating servers because in a large enterprise environment, that can be a large number. But get the freaking facts right. The reason this was so impactful is that it was large corporations affected. And the fix was a very manual process since Microsoft had a "feature" that put everything into "recovery mode" after two failed boots.

Do you mean the windows code that loads drivers? What do you think the catch block should when it reads a file full of empty bytes? ignoring the file would mean booting up without the security features the system was supposed to have, the fault is mostly at crowdStrike
@@omri9325 i agree with that, just that pretty much any 3rd party driver can cause BSOD bootloop is a massive vulnerability. I dont know maybe MS could add a group policy that adds a standard flow where windows creates "driver backup point" before any new driver updates, if after driver update repeated BSOD revert to driver backup point and contain the problem driver with alert and log.
@@chinesesparrows No? It's a driver with kernel access. This makes the driver very powerful but also makes crashes easier, due to the fact that the OS cannot babysit it. I'm pretty sure you can cause a kernel panic on linux by writing a bad driver as well

Crowdstrike is ransomware, they just have a different payment plan. You pay up front for the privilege of being ransomwared at some unknown point in the future. Turns out the unknown point in the future was today! Surprise!
The other problem is not just bitlocker, but if your company locked the microsoft account so you can only sign in from company devices to get the recovery key, but all your company devices are hosed. I can sign into the account from my personal linux box, but it just says it's restricted, and I can't do anything, or get the recovery key. I was on hold with IT support for hours today, and at one point, the phone system hung up on everyone, and calling back the number went to a busy signal for the next hour. I spent 3 more hours on hold with IT, and they either answered when I went to get something to eat, or hung up on me again. What a cluster F
And don’t forget that Crowdstrike was responsible for the 2016 story that Russia hacked the DNC in order to get dirt on Hillary and favor Trump. Which was a lie.
I literally spent my entire friday manually fixing computers and explaining to people at remote locations how to fix their computers. Our entire IT department became helpdesk because of this update. You don't know the pain of explaining to a non-tech person over the phone - how to make a bootable USB, boot to it, and then enter their bitlocker recovery key so they can delete a file via command prompt until you've done it personally. I got to do that dozens of times on Friday and theres going to be lots more of this for the foreseeable future... I cannot express how much this sucks to fix even though its a relatively simple fix. It just can't be automated and it's horrible for that reason.

They failed to do a smoketest of their agent after build but before deploying it worldwide. Sounds like their software and update development process is just really not up to professional software engineering standards. At Meta, we had to have other engineers, sometimes multiple, review diffs before they would be accepted. And then there were multiple layers of CI/CD testing before exponential deployment with canary testing. You don't just push new code to all the machines all at once, because it's way too dangerous.
things go wrong even after full in-house testing. that's why you have canary testing and phased roll outs. the ceo comes across as totally disingenuous and is ultimately the reason for the company's poor practices.
the fact that one company can take everything down like this is scary, one bad actor and this could've been a mass malware attack instead of a simple driver error

The problem with the bootable USB thing is that a lot of corporate devices block booting from USB by default, which means the IT Team would have to tell the end user the BIOS password to get into the BIOS to change the boot order to enable booting from USB. Its a total nightmare!
Yeah, as a former IT support bod in logistics, taking a user through the steps will be painful and in some cases practically impossible.

I mean, Windows might be the least secure how most people use it, but there's another huge facet to why it's the target of randsomware: it's absolutely dominates the end-user/workstation market, especially when you are wagering the victim can't just restore from a backup and ignore you.

@@Texas3Percenter This specific issue is not exclusive to Windows. This is an issue of operating systems architecture and how drivers are able to run in Kernel mode. Falcon have Kernel driver for Linux, Windows and macOS. The IT departments of companies are asking the OS to load Falcon driver an allow it to run in Kernel mode, allowing it to watch for user data but also enabling it get OTA updates and not able to choose of get or not the update. Same bad driver could be for Linux or macOS.
@@unaquetzadillaalso, macOS still needs antivirus/endpoint protection. It just works a bit different and the audience of people who get MacBooks at work is probably more technical
Just what I was thinking. The reason Windows is targeted more is because it’s sitting on 73% of desktops. The PC Security channel showed that malware vendors absolutely have Linux versions of their tools. It is not immune.
@@unaquetzadillaWhat you said is partly true. In my previous role, I deployed crowdstrike for a major broadcaster and one common misconception in all of this, is that crowdstrike can push updates to customer endpoints without their knowledge or consent. It's simply not true. Endpoint management is handled centrally by IT admin and we can choose if we want to use the latest Falcon sensor version or not. You can of course configure crowdstrike to auto update the sensors but that would be ludacris.
I was dealing with this today as an IT tech. Oh boy, What a joke. Took around 20 minutes on average per person affected. Since hundreds of devices were affected it made for a long day... :(
Where in the hell is the testing cluster they should have deployed to first? CrowdStrike should deploy their Falcon updates to all their own machines and if they don’t BSOD after a week THEN release to the entire galactic empire.
Lets accept for a second that they did that, because they probably did, they've been doing this for a while. They probably did NOT send out a null file. So somewhere between them releasing it and the end users getting it, it got nulled out. That's where the problem was. Azure went down right before all this happened...
This is tough because as an antivirus you want updates deployed as quickly as possible. If some new exploit comes out you wouldn't want your customers to be vulnerable to it for over a week.
If they tested, then they either didn’t test what they were deploying or they didn’t deploy what they tested. This is a basic control problem. I have had to point out to management numerous times that whatever cockamamie plan they have for maintaining a claim that the product was tested, that they weren’t testing what they were deploying. That internal process needs to be seriously scrutinized.
@@piquat1 i cannot believe they were smart enough to do a phased roll out, but then neglect a simple hash check of the deploy-able. the evidence suggests they did neither.
@@petargolubovic5300 Agreed Mac booted Anti-,virus software from the kernel after creating an endpoint security API for them to use and Linux has ebpf hooks and bpf programs to screen for AV to screen for potentially malicious activity with a guarantee that they can't crash the kernel (bpf programs have strict security/stability guarantees while being non-turing complete)
Honestly, when I was an i.t. call center tech, the older people could often be counted on to listen to my instructions and not go off script. It depended on the person of course, but I was often able to wrangle an older person to listen. 😅
Our company installed CS on thousands of Windows clients recently. A few weeks ago they uninstalled it because it was causing massive system performance issues. Giant bullet dodged. On the Windows side, it's just nuts that any driver causing continual stop errors is not auto disabled /quarantined by the OS.
The driver affects the boot process which is why it wouldn’t fail until a restart. Cant auto detect a failing driver before that driver gets used by the system.
Most drivers do not, but generally AVs mark theirs as a boot driver, so the system cannot boot if it is failing. So it's not just "any driver" as you state.
Their asses are already opened up to lawsuits big time! 3 billion in cash $ watch it evaporate! Their customers are now PUBLIC DATA which is a huge liability for their future cash flows too.
"Windows is the only OS that is insecure enough to have problems like this" Let me tell you why that's bullshit - Crowdstrike did this to our production Linux fleet back on April 19th.
Thats why they call IT. The amount of people who do not know how to log in to their work email on their phones so I dont have to read out their 69000 digit recovery key is incredible... and then hope to god that they wrote it down correctly or heard you correctly... and then hope to god that they enter it correctly so that 75 year old Dorothy doesn't have to be talked through booting into safe mode again BEFORE you have to talk her through deleting a file.
So, there was this episode of _The Munsters_ that followed the same idea... They wound up blowing up a very expensive antique box to find a video cassette (and not a heap of treasure).
There was a post on reddit about a huge org that has the bitlocker keys on a box with bitlocker and they don't know where the key for the centralized box is because the documentation is also behind bitlocker
I did that by mistake once, I stored by password database on the bit locker drive, the bit locker password was on the password database. Lucky I have a offline backup of the password database.
@@tatumsh9 Or maybe the company shouldn't limit the microsoft account to only be accessed from company devices, when the only company device is hosed!

Root cause analysis - 1) Using Windows for mission critical work in 2024 2) Terrible code that somehow made it past code review 3) Build system that corrupts files 4) No validation checks prior to rollouts 5) Rollouts to the entire install base rather than a staged rollout

Linux versions of Falcon also hook into the kernel. Talking about how this fuck is somehow because it is Windows is disingenuous. Why can't we just blame Crowdstrike and just Crowdstrike instead of bringing up and blaming Microsoft?
i wholly agree with you, this guy just wanted to hate just because its windows, i also don't like windows myself but its pretty disingenuous to blame Windows when its not their fault.
@@Abaddon231 falcon also exists on Linux and Mac. Is Falcon there because of Windows? Falcon exists because there are malicious actors, not because Windows exists. Then he mentions kernel drivers without acknowledging that this also happens on Linux and the fact that if you want a solution like Falcon, they should hook into the kernel, because that is how they can most effectively do their job. Or why bother having and EDR at all. He would have been able to effectively convey his message instead he went all mainstream media ranting about Windows. This shit isn't his forte, but he still has a take on it. Low Level Learning has a much better and nuanced take on this.
Falcon on Linux uses ebpf hooks which can't crash the kernel (they have extraordinarily strict guarantees, restrictions, and limitations that would prevent an ebpf program from doing that, they aren't even turing complete) Apple on the other hand has an API for AVs to do their job and doesn't permit them from installing a driver.
@@brandonn.1275 Falcon on Linux in User Mode uses eBPF. There are still many systems that use Kernel mode. Although Falcon is transitioning to User Mode, Kernel Mode is still officially the default mode for Falcon on Linux. Per official CrowdStrike docs. Many of my Linux systems still use Kernel Mode.
My favourite part of the disappearing air traffic example is that while they will occasionally get crippling downtime from their infrastructure, Southwest still running primarily Windows 3.1 with a sprinkling of Windows 95 here and there rather isolated them from the CrowdStrike issue.
OMFG, Theo thank you I had no idea how terrible this was!! The encrypted bitlocker problem is absolutely horrendous! Oh my god, I could maybe get this sorted but most people definitely can't, this is BAD!
its shockingly inept. the fact they did a rollout with no percentage based rollout and metrics on how the rollout was performing and no rollback plan is literally insane and then on top of that the fact their deploy pipeline distributed this with tests either not run or failed.... makes it seem like theres more to this story than just oh we just pushed some bad code. There are safeguards in code and policy that should prevent this.
also the fact it's literally *in* the kernel and not something like ebpf where it can have hooks in the kernel and have saftey guarantees about it not crashing the computer... thats microsoft fault for writing a steaming pile of bitrot masquerading as an operating system.
Crowdstrike is the company that shuts down your computer when you're hacked, and they wont allow it to turn on until they check manually how bad is the hack...
We don’t shut it down, we hit a button labelled “network containment” which only allows it to communicate with the admin dashboard for forensic analysis. Your MSSP should be ringing you immediately if they have to use network containment
After using Linux for 10 years and Arch for 5 years I will say... use Mac instead. If you need something linux or windows specific you can spin up a vm with Parallels. And overall, mac laptops lasts long and have overall great performance & build quality. As for servers - linux is the only choice.

One point to make, (I am a Mac user so don’t come at me 😂) Microsoft has the biggest market share for desktop by a large margin so make sense for hackers to focus on them, not sayings it shouldn’t be more secure but also theywill get bigger focus from hackers just due to market share
Linux runs most of the world's servers though. If Linux is much more vulnerable than Windows it would make more sense to focus on Linux since you can have more control. The thing is Windows simply is a lot less secure and more prone to crashes like this.

“Pretty much every PC in the world”… What? No. Nobody’s home computer would have CrowdStrike software. No Mac or Unix or Linux systems would be affected. The number of business computers running Windows with this software loaded is absolutely mind-boggling, though. I mean, we’re in seriously WTF territory. I hope people can get things straightened out quickly, especially for the more critical areas.
There was an issue with CrowdStrike on Debian several months back, that caused the OS to not boot… This isn’t the first time CrowdStrike has massively broken an operating system
And Hammond gets a shoutout here as well 😎. Also, great video of course, really enjoyed the take on how to and how not to communicate in such a situation.
Companies that run something like CrowdStrike often use BitLocker AND have take measures to block USB devices. You have to lock a Windows down way more to be ‘compliant’ for auditing
If you search hard enough, you'll find that there were two Linux Distros that got a bad update from CrowdStrike that resulted in the same issue. I think I read that it was cases of kernel panics in this case.
At first glance this is actually hilarious to see, but I feel so bad for the patients at hospitals affected by this. That's the worst part. Sometime like this will literally cost lives. Crazy
One thing though, using a kernel mode driver is not exclusive to crowdstrike. Many other AV/EDR systems use drivers as well. In fact a very similar thing happened with Symantec a while ago.
At this point windows is going to need to boot Anti- virus software out of the kernel and provide an API for AVs to do their job instead of having them insert a driver into the kernel. This is what Mac did when they booted AV vendors from the kernel after publishing an endpoint security API for them to use. Linux has something similar in the form of ebpf hooks and bpf programs that can run in Kernelspace while being guaranteed to be unable to crash the kernel.
iirc even linux security software sometimes needs kernel mode drivers. stuff like cloudstrike can avoid needing a driver on linux bc they can just use ebpf tho. mac still needs a kernel driver.
Yeah the affected CS update just happened to target a Windows named pipe vulnerability, so in this case only Windows was updated. So to just blanket blaming using Windows like OP did is a bit lazy. Their Apple and Linux customers just got lucky.

3:40 Not true. Falcon sensor is available for Mac and for Linux too. The real reason that it has happened on Windows only, because 1.: CrowdStrike seemingly made a mistake only in the Windows driver, 2.: Windows is waaaay more popular in businneses (both server and desktop side) than anything else.
this seems like one of those applications where you'd expect every pull requests to go through a "committee" such that you don't have some one-guy write a bug into the code..

The real questions that everyone should be asking is ...... What happened during, DURING the bootloop, because that's when anyone can access ANYTHING....and yesterday was an entire day of chances!
Every single time something really shitty like this happens.. almost without fail. EVERY SINGLE TIME: Look at the education of the CEO. George Kurtz: Degree in Accounting. (no formal science, tech, engineering, or computer education of any kind... I can see he claims he can program but as far as I can tell, he's never actually worked a job involving programming or science of any kind.) The fact that this company pushed a driver rollout to hundreds of millions of people SIMULTANEOUSLY without checking it worked first tells you EVERYTHING you need to know about how this dude runs this company. If he had any actual knowledge of computer systems he wouldn't have allowed that to happen. And yet he did. When will the world wake up and start to realize that shit like this always happens when you put business people in charge of technology they don't comprehend. Now I'm not saying George Kurtz knows nothing about programming, its completely fair to be self-taught. But as far as I can tell he never did anything science-related at his job in any capacity, and his claim to fame is that he co-wrote a book about computer hacking with some actual computer scientists back in the 90s. Ever since then everyone has treated him as though he himself is a computer scientist, even though he's not actually. And after a #$#@ up this extraordinarily bad, it seems it was wrong to believe he knew what he's doing. There's NO WAY a mistake this bad could have happened without his express knowledge and instruction that this is how they operate. Stop trusting bean counters with important technology.
I don't understand why everyone is so caught up over this "kernel level driver" thing - this is not built for consumer PC's. EDR solutions REQUIRE kernel level access to even be effective at catching as much malicious software as possible - it gives you such an upper hand and allows you to check and scan EVERYTHING on the machine. For a consumer non-business user device, this is super undesirable and would not be a good solution - but for a business that requires intense security to protect their data? At least for the moment, there is no other way. Those saying that Windows is the only OS unsecure enough to need this and jabbing at windows... Yeah. Just Windows things. I mean it's not like Linux and MacOS are perfectly secure, but the general consensus is those OS's are more resilient to viruses than windows. (Though it's not a bad thing to point out, that most malware is written for windows, because of how ubiquitous it is in industry.)
No, they do not require kernel level access. In fact they are not allowed to have kernel access on Macs and even Linux is moving over to ePBF where a bad driver can't crash the system.
@@uzlonewolfkernel drivers are allowed in macs. and linux kernel drivers are limited in a number of ways. notably, a kernel module is needed to monitor syscalls for processes you didn't spawn. and seccomp filters don't let you count anything, only filter.
@@uzlonewolf Because of the way that Windows is built and the way that threats/malware currently operate, the only way you can hope to catch everything, at least right now with current technology, ideas, and software, is with kernel level access. Hopefully this changes, but as of right now it is what we have. I am only applying this to Windows however because, obviously, we've found alternate solutions for Mac and Linux and have not needed to do this.
Ooooh yeah I love the voice that tech influencers have when they weren't expecting to go recording and their humanness comes out more??? Like, idk what it is about it, it sounds like you just woke up (compliment)
@NormCantoral that makes sense, I just thought that interpretation was so unreasonable that it was more likely he just hasn't ever seen a software bug of this scale and severity that was caused by something so easily preventable. made sense to me bc he runs a tech channel.
I find a lot of the take in this video to be misguided. Modern anti-malware software works by monitoring application behavior in addition to traditional known signature matching. The only way to get the level of access to protect at the level is through kernel modules (aka drivers). The falcon scanner for linux also has a kernel module for this reason. While there are a number of vulnerabilities in Windows, it is also the most used desktop OS. Securing desktops is a lot harder than securing a server because you have a user who may or may not do stupid stuff that you worry less about than a server. There are multiple reports of crowdstrike falcon causing linux kernel panics...they just are not as wide spread as windows.
Wow, fortune 50 company I used to work for had all the users on windows, of course, the back end for the most critical things ran on RHEL. Wonder how they're doing now. lol
Friday morning at the office I was jokingly asked if I caused it. The day before in the company Town Hall I announced that I cancelled the CrowdStike contract and we have mostly removed Falcon from all devices. Only two left over machines had issues.
@@Micloren basic Falcon didn’t do much and got better data from the Checkpoint and Fortigate UTMs. Unless you shell out for the full SIEM, felt limited. Decided to up the network security instead and pay for a SOC/NOC service.
The amount of nonsense I haven't dealt with over two decades, since switching away from Windows to Linux in 2006. I was on most versions of Windows since 3.1 in 1991 (3.1, 3.11, 95, 2k, XP, NT, 7, 8, 10, the last three for work), and Linux has been like a breath of fresh air for 18 years. It's really nice to be able to actually control everything on my system.
Not sure what is scarier, that CrowdStroke released a bad version or that so many companies just blindly went with it without testing and staging it first.
Airlines, banks etc. without testing updates in isolated environments is absurd yet reality. And most systems if done properly don't even need antivirus because they suppose to be nit connected to public networks. So this would be some management's push to order that software. Important systemd should be setup in a way that assumes that something goes wrong that means having staging environment. This incident shows massive tech incompetence either by itself or with push if higher management wanting to reduce cost or just fall on lies of vendors of how great everything would be if company trust them blindly.
My rage at everyone downplaying this for CrowdStrike is immeasurable. This is a billion dollar company, with a B, trusted by critical government, public, and private services and they shafted each and everyone. The lack of outrage from our authorities is absolutely disgusting. Speaks a lot to the state of cybersecurity and tech in general
Hah! That USB boot idea would be fine, if it weren't booting you into safe mode after unlocking your bitlocker. That's prime attack territory for planting a rootkit while "helping" you clean up that crowdstrike BSOD. You'd have to audit everything about how that USB key came to be and all the software on there, from extremely trustworthy sources.
At this moment there are probably hundreds of foreign agents planted at all levels in important companies. Imagine the damage that can/will be done when the time comes.
While I hate Microsoft about as much as Apple nowadays, your take on Windows in this specific case is totally wrong and uncalled for. Only Windows was affected because only that update was affected. Windows doesn't have anything worse than Mac or Linux here. Also Mac and Linux could've been just as much affected. That whole section is very cringe. Edit: I mean the section starting at 3:35 The rest of the video is a-ok
Yeah, this could’ve happen to any of the OSs especially in a corporate setting. That said, Apple actively discourages kernel extensions and have built alternatives in user mode.
In this particular case I *suspect* Linux would handle a faulty kernel module bettter, but I'm not sure. This is crowdstrikes fault for sure, but I wonder if the way Windows handles these kernel level drivers could be better though.

3:34 - People always think hackers target Windows because it is insecure but that's actually not true. Microsoft Windows is the most used at 72.22%, followed by Apple's macOS at 14.73%, desktop Linux at 3.88%. Just by looking at this, one can easily deduce what operating system a sensible hacker would target if they wanted to create malware. So, its not that the other Operating Systems are secure but a matter of ROI. If you spend a month creating malware for windows you get 72% possible targets while on the other hand spending a month creating macOS malware will give you only 14.73% possible targets.

@t3dotgg Your description of the Windows / Active Directory / BitLocker login process is inaccurate. The bitlocker key is not retrieved from AD or other remote DB when you auth, but rather from the device’s local TPM.

That sucks! I have to close on 2 real estate deals Monday. They won't happen til this is fixed. Thanks, banks, for using crowdstrike! If you were using Linux instead of Windows, you wouldn't need to.
I can't imagine the infrastructure that could let this happen. I have worked at a lot of companies, and even ones that haven't always had the best practices. But every single one of them had measures in place that would have caught this problem in at least 5 places before a customer got it.
The take on windows being the least secure OS is a bit biased. The real reason why most cyber attacks happen through windows is because 1. It is the most used OS by a huge margin. 2. Since it is so widely used, hackers focus on finding vulnerabilities in windows instead of other OS like Linux.
It's purposely written like swiss cheese, full of back doors and vulnerabilities so they and intelligence agencies and access you computer any time they want. Linux is not. So Linux users don't have to worry about viruses or malware and don't have to put middle-man software between them and their machines to protect them from their malware/spyware OS. The only thing I use on my Linux servers is a firewall and Fail2Ban to prevent brute force pwd cracking.
Why does a badly written driver stop the machine from booting? Shouldn’t that driver just be skipped and whatever device it targets not work? Seems like a terrible design within Windows.
It is not Windows design issue. It is driver being written as kernel-mode, to gain extensive privileges over system in attempt to prevent malware activity. Meaning it becomes required to boot before even Windows takes over. And if it crashes, well, Windows hadn't booted yet. And it cannot exclude this driver from list as it is listed as mandatory. Loop repeats. And no revovery window appears because system crashes before it even reaches said state. Someone even said that CrowdStrike already did similar stuff to Linux systems at 19-th April. Linux and Macs versions of CrowdStrike are also using kernel mode drivers, albeit with some nuances (like there being restricted version for Linux). And similar case could've also caused bootloop (on Linux BSOD is more known as Kernel Panic).
@@DimkaTsv This is a Windows design issue. Try to load exact same file as a Linux module. It will not crash, but You will have a simple warning and that's it.
the prob is it had to be done as a driver to get kernel mode. MS tried to develop and license an interface that would allow that without having to load potentially sketchy kernel-mode drivers before boot, but then the EU stepped in and forbade it, because, they figured, it would give MS an unfair advantage on the market, if they were to choose who would get costly privileged kernel access. So you can blame the EU as well. Or you can blame Crowdstrike for knowing they are doing very, very sensitive stuff, but OTA-pushing a bad, untested update regardless.
@3:42 - Re: This only happens on Windows, because it's the only one that's insecure enough to have problems like this? I don't know about this .. if Linux or Mac had the most marketshare, such that a company like CrowdStrike ran its software in the kernel to prevent malware, and they pushed a bad update .. maybe the screen wouldn't be *blue*, but you'd have a kernel OOPS or a reboot or a kernel panic, etc. It's not because Windows is more inherently less secure. (Even though that might be the case) And it's just a pile of hacks on-top of each other? Dude, I think Windows has quality problems, but I think this statement is just too simple and immature. I've lost a lot of respect for you now.
You really lost me on this one theo. There isn't anything here that couldn't happen on Linux, in fact, it did -- about a month ago. It's not guarding your bootup and preventing you from booting in an unsafe environment, its just a broken kernel mode driver. I got bluescreened. You know what happened? Windows dumped it's ram, rebooted into last know good config, i shrugged, and moved on. I can't believe this overshadowed Trump being shot to the point i hadnt heard about the latter until an hour ago
@@mwahlert "omg Windows"... No... Omg the market share! Bet you didn't know Windows ran in all *these* places :3. "Omg Windows needs this?" Up until 2019 CS didn't even have any offensive antimalware tech, it purely was marketed as a distributed, crowd sourced IDS for setting a baseline and then detecting anamolies (whether abnormal for your business, or just plain university unusual activity) "Omg a driver?" Yeah .. if you want network inspection (NDIS) or any kind of endpoint DLP, and unless you want your employees ripping it out, changing it's permissions, etc. As someone inconvenience by it daily since i run executables classified as "hacking tools", CS does an amazing job of preventing bad stuff from running, no matter who you are. First CS issue I've ever faced the wasn't as simple as requesting an exception for a given piece of software.
I mean this happened last night and trump got shot 6 days ago.. living under a rock sounds like a choice also windows is the hodgepodge of configurations and programs and apis he said it is. Everything is an inconsistent mess and it seems reasonable to think that would leave more security issues..

BS First only Enterprise PCs and Servers were affected unless someone bought Crowdstrike. Second, only a fraction of devices with Crowdstrike were affected. I work for a major nonprofit Hospital and about 25% of our servers were affected. I spent 11 hours manually remediating servers because in a large enterprise environment, that can be a large number. But get the freaking facts right. The reason this was so impactful is that it was large corporations affected.

They failed to do a smoketest of their agent after build but before deploying it worldwide. Sounds like their software and update development process is just really not up to professional software engineering standards. At Meta, we had to have other engineers, sometimes multiple, review diffs before they would be accepted. And then there were multiple layers of CI/CD testing before exponential deployment with canary testing. You don't just push new code to all the machines all at once, because it's way too dangerous.
And deployment of system files, much less kernel level files should have a hash/checksum too, no?
And still they fucked up all their systems for a DNS error

@@unaquetzadillaWhat you said is partly true. In my previous role, I deployed crowdstrike for a major broadcaster and one common misconception in all of this, is that crowdstrike can push updates to customer endpoints without their knowledge or consent.

Lets accept for a second that they did that, because they probably did, they've been doing this for a while. They probably did NOT send out a null file. So somewhere between them releasing it and the end users getting it, it got nulled out. That's where the problem was. Azure went down right before all this happened...
This is tough because as an antivirus you want updates deployed as quickly as possible. If some new exploit comes out you wouldn't want your customers to be vulnerable to it for over a week.
If they tested, then they either didn’t test what they were deploying or they didn’t deploy what they tested. This is a basic control problem.

On the Windows side, it's just nuts that any driver causing continual stop errors is not auto disabled /quarantined by the OS.
are you sure you aren't neo? bc that's some wicked bullet dodging ability
The driver affects the boot process which is why it wouldn’t fail until a restart. Cant auto detect a failing driver before that driver gets used by the system.
Kernel drivers will cause severe problems on any OS, not just Windows. Just search RHEL CrowdStrike if you don't believe it.

its insane that crowdstrike didnt integration test the update, and even more insane that mission-critical infrastructure is OK with automatic OTA patches.
How in the WORLD do you not test the system BEFORE you send it out. CRAZY!
Doesn't Microsoft force updates on their Windows users too?
“Pretty much every PC in the world”… What? No. Nobody’s home computer would have CrowdStrike software. No Mac or Unix or Linux systems would be affected. The number of business computers running Windows with this software loaded is absolutely mind-boggling, though. I mean, we’re in seriously WTF territory. I hope people can get things straightened out quickly, especially for the more critical areas.
CrowdStrike engineers: “Update is ready, let’s deploy it to the world Friday morning, and let’s test on production”
There was an issue with CrowdStrike on Debian several months back, that caused the OS to not boot… This isn’t the first time CrowdStrike has massively broken an operating system
Their reaction to that issue suggested they really did not care. It should have been a red flag.
And Hammond gets a shoutout here as well 😎. Also, great video of course, really enjoyed the take on how to and how not to communicate in such a situation.
Absolutely! If I didn't shout him out in the video directly that was an absolutely L on my part
@@t3dotgg Nono, you did, 12:40 👍Hammond collab when? 😉
Companies that run something like CrowdStrike often use BitLocker AND have take measures to block USB devices. You have to lock a Windows down way more to be ‘compliant’ for auditing
If you search hard enough, you'll find that there were two Linux Distros that got a bad update from CrowdStrike that resulted in the same issue. I think I read that it was cases of kernel panics in this case.
3rd party access to kernel mode plus cloud service = recipe for disaster. Crowdstrike - aptly named - soon to be a Null company pointer.
RIP to the intern😢
If an intern did the coding or deployment, then their supervisor needs to be in big trouble.
At first glance this is actually hilarious to see, but I feel so bad for the patients at hospitals affected by this. That's the worst part. Sometime like this will literally cost lives. Crazy
One thing though, using a kernel mode driver is not exclusive to crowdstrike. Many other AV/EDR systems use drivers as well.
In fact a very similar thing happened with Symantec a while ago.
At this point windows is going to need to boot Anti- virus software out of the kernel and provide an API for AVs to do their job instead of having them insert a driver into the kernel.
This is what Mac did when they booted AV vendors from the kernel after publishing an endpoint security API for them to use.
Linux has something similar in the form of ebpf hooks and bpf programs that can run in Kernelspace while being guaranteed to be unable to crash the kernel.
iirc even linux security software sometimes needs kernel mode drivers.
stuff like cloudstrike can avoid needing a driver on linux bc they can just use ebpf tho. mac still needs a kernel driver.
Yeah the affected CS update just happened to target a Windows named pipe vulnerability, so in this case only Windows was updated.
So to just blanket blaming using Windows like OP did is a bit lazy. Their Apple and Linux customers just got lucky.

@@dead-claudia Mac doesn't allow AVs into the kernel anymore instead they published an API for them to use and won't allow AVs to install kernel extensions anymore. In fact kernel extensions have been deprecated for a while now and only userspace system extensions can be installed.

3:40 Not true. Falcon sensor is available for Mac and for Linux too. The real reason that it has happened on Windows only, because 1.: CrowdStrike seemingly made a mistake only in the Windows driver, 2.: Windows is waaaay more popular in businneses (both server and desktop side) than anything else.
this seems like one of those applications where you'd expect every pull requests to go through a "committee" such that you don't have some one-guy write a bug into the code..
Or malware. Seriously, if this could happen due to some stupid mistake, imagine how bad it would have been if an actual bad actor had social engineered their way into position to abuse the hell out of it.
Or there is a nice vulnrability sitting there for malware to poke at. I'm sure Falcon is going to be put through some fuzzing by the bad black hats.
Problem with bootable USB device is that, a lot of corporate systems also disable USB for security reasons, this gets more interesting 😂

Every single time something really shitty like this happens.. almost without fail. EVERY SINGLE TIME: Look at the education of the CEO.
George Kurtz: Degree in Accounting. (no formal science, tech, engineering, or computer education of any kind... I can see he claims he can program but as far as I can tell, he's never actually worked a job involving programming or science of any kind.)
The fact that this company pushed a driver rollout to hundreds of millions of people SIMULTANEOUSLY without checking it worked first tells you EVERYTHING you need to know about how this dude runs this company. If he had any actual knowledge of computer systems he wouldn't have allowed that to happen. And yet he did.
When will the world wake up and start to realize that shit like this always happens when you put business people in charge of technology they don't comprehend. Now I'm not saying George Kurtz knows nothing about programming, its completely fair to be self-taught. But as far as I can tell he never did anything science-related at his job in any capacity, and his claim to fame is that he co-wrote a book about computer hacking with some actual computer scientists back in the 90s. Ever since then everyone has treated him as though he himself is a computer scientist, even though he's not actually. And after a #$#@ up this extraordinarily bad, it seems it was wrong to believe he knew what he's doing. There's NO WAY a mistake this bad could have happened without his express knowledge and instruction that this is how they operate.
Stop trusting bean counters with important technology.
I don't understand why everyone is so caught up over this "kernel level driver" thing - this is not built for consumer PC's. EDR solutions REQUIRE kernel level access to even be effective at catching as much malicious software as possible - it gives you such an upper hand and allows you to check and scan EVERYTHING on the machine. For a consumer non-business user device, this is super undesirable and would not be a good solution - but for a business that requires intense security to protect their data? At least for the moment, there is no other way.
Those saying that Windows is the only OS unsecure enough to need this and jabbing at windows... Yeah. Just Windows things. I mean it's not like Linux and MacOS are perfectly secure, but the general consensus is those OS's are more resilient to viruses than windows. (Though it's not a bad thing to point out, that most malware is written for windows, because of how ubiquitous it is in industry.)
No, they do not require kernel level access. In fact they are not allowed to have kernel access on Macs and even Linux is moving over to ePBF where a bad driver can't crash the system.
@@uzlonewolfkernel drivers are allowed in macs. and linux kernel drivers are limited in a number of ways.
notably, a kernel module is needed to monitor syscalls for processes you didn't spawn. and seccomp filters don't let you count anything, only filter.
@@uzlonewolf Because of the way that Windows is built and the way that threats/malware currently operate, the only way you can hope to catch everything, at least right now with current technology, ideas, and software, is with kernel level access. Hopefully this changes, but as of right now it is what we have. I am only applying this to Windows however because, obviously, we've found alternate solutions for Mac and Linux and have not needed to do this.
Ooooh yeah I love the voice that tech influencers have when they weren't expecting to go recording and their humanness comes out more??? Like, idk what it is about it, it sounds like you just woke up (compliment)
@@NormCantoralthose weren't tech issues
@NormCantoral that makes sense, I just thought that interpretation was so unreasonable that it was more likely he just hasn't ever seen a software bug of this scale and severity that was caused by something so easily preventable. made sense to me bc he runs a tech channel.
I find a lot of the take in this video to be misguided. Modern anti-malware software works by monitoring application behavior in addition to traditional known signature matching. The only way to get the level of access to protect at the level is through kernel modules (aka drivers). The falcon scanner for linux also has a kernel module for this reason. While there are a number of vulnerabilities in Windows, it is also the most used desktop OS. Securing desktops is a lot harder than securing a server because you have a user who may or may not do stupid stuff that you worry less about than a server. There are multiple reports of crowdstrike falcon causing linux kernel panics...they just are not as wide spread as windows.
Do note Crowdstrike has a kmode driver for Linux as well. And that also broke RHEL recently... OOPS
Yup, this isn't just an accident. It's a pattern.
Wow, fortune 50 company I used to work for had all the users on windows, of course, the back end for the most critical things ran on RHEL. Wonder how they're doing now. lol

I’m shocked how much windows there is in infrastructure
Friday morning at the office I was jokingly asked if I caused it. The day before in the company Town Hall I announced that I cancelled the CrowdStike contract and we have mostly removed Falcon from all devices. Only two left over machines had issues.
Curious, what was your reason for cancelling? Was it affecting productivity?
@@Micloren basic Falcon didn’t do much and got better data from the Checkpoint and Fortigate UTMs. Unless you shell out for the full SIEM, felt limited. Decided to up the network security instead and pay for a SOC/NOC service.

The amount of nonsense I haven't dealt with over two decades, since switching away from Windows to Linux in 2006. I was on most versions of Windows since 3.1 in 1991 (3.1, 3.11, 95, 2k, XP, NT, 7, 8, 10, the last three for work), and Linux has been like a breath of fresh air for 18 years. It's really nice to be able to actually control everything on my system.
Not sure what is scarier, that CrowdStroke released a bad version or that so many companies just blindly went with it without testing and staging it first.
this was supposed to be more like a config or signature update. this is like pushing a bad signature file to windows defender and causing it to crash.
Airlines, banks etc. without testing updates in isolated environments is absurd yet reality. And most systems if done properly don't even need antivirus because they suppose to be nit connected to public networks. So this would be some management's push to order that software. Important systemd should be setup in a way that assumes that something goes wrong that means having staging environment. This incident shows massive tech incompetence either by itself or with push if higher management wanting to reduce cost or just fall on lies of vendors of how great everything would be if company trust them blindly.
The update was automatic I think D:
My rage at everyone downplaying this for CrowdStrike is immeasurable. This is a billion dollar company, with a B, trusted by critical government, public, and private services and they shafted each and everyone. The lack of outrage from our authorities is absolutely disgusting. Speaks a lot to the state of cybersecurity and tech in general
Hah! That USB boot idea would be fine, if it weren't booting you into safe mode after unlocking your bitlocker. That's prime attack territory for planting a rootkit while "helping" you clean up that crowdstrike BSOD. You'd have to audit everything about how that USB key came to be and all the software on there, from extremely trustworthy sources.
At this moment there are probably hundreds of foreign agents planted at all levels in important companies. Imagine the damage that can/will be done when the time comes.
Southwest Airlines unaffected. Use older version of Windows. Brilliant. Latest/Greatest not always good.
Could also be that they simply not using Falcon...
The most detail explanation I’ve seen. Thank you! Great video.
While I hate Microsoft about as much as Apple nowadays, your take on Windows in this specific case is totally wrong and uncalled for. Only Windows was affected because only that update was affected. Windows doesn't have anything worse than Mac or Linux here. Also Mac and Linux could've been just as much affected. That whole section is very cringe.
Edit: I mean the section starting at 3:35
The rest of the video is a-ok
Yeah, this could’ve happen to any of the OSs especially in a corporate setting. That said, Apple actively discourages kernel extensions and have built alternatives in user mode.
In this particular case I *suspect* Linux would handle a faulty kernel module bettter, but I'm not sure. This is crowdstrikes fault for sure, but I wonder if the way Windows handles these kernel level drivers could be better though.
I believe cloud strike has uploaded a faulty module not a while a go there was a red hat incident posted for it. But I guess it was not as widespread.
@@fallingintime But was it as catastrophic as a unbootable BSOD ?
Edit: Although it would probably be hard to compare unless it was at least a similar mistake.
@@jonnyso1 kernel panic that required a kernel fix I believe. Probably wasn't widespread as it only affected a specific kernel version and kernel updates are not ota

3:34 - People always think hackers target Windows because it is insecure but that's actually not true. Microsoft Windows is the most used at 72.22%, followed by Apple's macOS at 14.73%, desktop Linux at 3.88%. Just by looking at this, one can easily deduce what operating system a sensible hacker would target if they wanted to create malware. So, its not that the other Operating Systems are secure but a matter of ROI. If you spend a month creating malware for windows you get 72% possible targets while on the other hand spending a month creating macOS malware will give you only 14.73% possible targets.
It's purposely written like swiss cheese, full of back doors and vulnerabilities so they and intelligence agencies can access your computer any time they want. Linux is not. So Linux users don't have to worry about viruses or malware and don't have to put middle-man software between them and their machines to protect them from their malware/spyware OS. The only thing I use on my Linux servers is a firewall and Fail2Ban to prevent brute force pwd cracking.

The take on windows being the least secure OS is a bit biased. The real reason why most cyber attacks happen through windows is because 1. It is the most used OS by a huge margin. 2. Since it is so widely used, hackers focus on finding vulnerabilities in windows instead of other OS like Linux.

Why does a badly written driver stop the machine from booting? Shouldn’t that driver just be skipped and whatever device it targets not work?
Seems like a terrible design within Windows.
It is not Windows design issue.
It is driver being written as kernel-mode, to gain extensive privileges over system in attempt to prevent malware activity. Meaning it becomes required to boot before even Windows takes over.
And if it crashes, well, Windows hadn't booted yet. And it cannot exclude this driver from list as it is listed as mandatory. Loop repeats. And no revovery window appears because system crashes before it even reaches said state.
Someone even said that CrowdStrike already did similar stuff to Linux systems at 19-th April.
Linux and Macs versions of CrowdStrike are also using kernel mode drivers, albeit with some nuances (like there being restricted version for Linux). And similar case could've also caused bootloop (on Linux BSOD is more known as Kernel Panic).
@@DimkaTsv This is a Windows design issue. Try to load exact same file as a Linux module. It will not crash, but You will have a simple warning and that's it.
the prob is it had to be done as a driver to get kernel mode. MS tried to develop and license an interface that would allow that without having to load potentially sketchy kernel-mode drivers before boot, but then the EU stepped in and forbade it, because, they figured, it would give MS an unfair advantage on the market, if they were to choose who would get costly privileged kernel access. So you can blame the EU as well.
Or you can blame Crowdstrike for knowing they are doing very, very sensitive stuff, but OTA-pushing a bad, untested update regardless.
@3:42 - Re: This only happens on Windows, because it's the only one that's insecure enough to have problems like this? I don't know about this .. if Linux or Mac had the most marketshare, such that a company like CrowdStrike ran its software in the kernel to prevent malware, and they pushed a bad update .. maybe the screen wouldn't be *blue*, but you'd have a kernel OOPS or a reboot or a kernel panic, etc. It's not because Windows is more inherently less secure. (Even though that might be the case) And it's just a pile of hacks on-top of each other? Dude, I think Windows has quality problems, but I think this statement is just too simple and immature.

You really lost me on this one theo. There isn't anything here that couldn't happen on Linux, in fact, it did -- about a month ago. It's not guarding your bootup and preventing you from booting in an unsafe environment, its just a broken kernel mode driver. I got bluescreened. You know what happened? Windows dumped it's ram, rebooted into last know good config, i shrugged, and moved on.
