Yep... I have a set of axes that are also excellent "hacking tools" The BIG problem with youtube is there is NO citation..., if you go read something like POC || GTFO , you will see they ALWAYS use citation to give credit, that has now basically disappeared in this space. Additionally a problem is too many dumbasses watching youtube videos, spoiling it by taking credit for shit that has been done underground for decades... a "real hacker", might spend years taking something apart.. or decades in a particular field , only to find that if they tell someone else, that within a weak they are boasting and taking credit and the whole area is shut down. Some would think wow years taking something apart... they must not be very good...... yep right .. go look at the PlayStation hacks and the amount of work that went into those. along with all the "fake" side traps with code in chips that was NEVER EVER executed, but people spent years analising and tehn giving up.
Afaik there are different versions of this board. The actual CH341 chip is both 3.3V and 5V compatible (which is why the mod even works to begin with) although some boards don't use the integrated 3.3V circuit others do.
Alternately, there are CH341 dongles with blue PCBs that have just a bunch of pin headers, rather than a fancy socket. This has a proper design: it has a jumper that lets you select between powering the CH341 chip from either USB power or an onboard 3.3v regulator, which is what determines the logic voltage (per the datasheet). You have to think about how to hook it up a little bit more since you don't have the socket, but if you're not confident modifying a PCB it'd probably be an overall better purchase - usually it's a little bit cheaper too.
@@ryjelsum Yes right! I have same dongle as Ed, and mine has 3v3 bug. I juat want to warn and inform to be carefull, some IC will not tolerate 5v as data pulses
[FacePalm] What do you think the deffinition of hacking is LMAO Hacking is the creative or unconventional use of tools, systems, or technologies to achieve a goal, often in ways they weren't originally intended to be used. It can involve exploring, modifying, or repurposing resources to solve problems, gain insights, or push boundaries. While hacking is often associated with computers, it can apply to anything where innovation or "thinking outside the box" comes into play.
He doesn't mention this in the video, but that CH341 device doesn't always work to read flash chips without desoldering. The problem is that in order to read from the flash chip, you have to power it. The CH341 can power a flash chip, but it can only output a limited amount of current. If the VCC rail connected to the flash chip is directly connected to other components too, it's possible the CH341 won't be able to power all those components, including the flash chip. In these cases, it's often best to just desolder the flash chip. Alternatively, you could connect a logic analyzer to the DI and DO pins of the flash chip, then power up the device. Use the logic analyzer to record the data stream as the CPU reads the flash contents. You may need to write a small program to convert the recording back into binary data though.
Just my experience, YYMV, but I used one to read and flash the BIOS of a Dell laptop. It functioned perfectly. I had to buy a second clip that connects to the chip since the first one refused to work.
@@MrWaalkman Yeah I'd say based on my experience that it works without desoldering about 80% of the time. It really just depends on whether your flash reader can provide enough power to the part of the board you're connected to.
Before unsoldering, just try plugging in the power cord in the device (but don't turn it on ofc) so it gets standby power to the chip. I've had this work on several devices. Some laptops require you to unplug the main battery as well if doing this.
1. add a electrolytic cap to the power rail (it looks odd, but, works) 100uF iirc. 2. Hold the reset pin on the uC low/high to stop the uC booting (if the bootloader uses the SPI bus it will corrupt your data). I had to do this to a tapo 200v3 to dump the firmware.
IMO, consumers should either: 1. Legally have FULL access to firmware OR 2. The C-Suite should be held legally liable for security breaches and face legal consequences equal to someone who makes and distributes malware as that's what they sold you.
Not really. They should not be forced. 1. Is their IP 2. Anybody can do mistakes. I think it's more simple: we should stop using the ones that we don't trust or like you said, the ones that don't open source their firmware.
I agree that this isn't the best. Just as a thought, imagine the law was done that way, then that means that if a company does give the full source of the firmware, then that would indemnify them and full onus would be on the buyer (and the vast majority of people wouldn't even be able to follow it, let alone detect vulnerabilities in it). It would be the equivalent of all of the ToS you agree to going forward being in a foreign language, and onus being on you for not knowing the language it is written in.

the most effective thing you can do with your time is to make instructions on how to do this, because at some point if this is again a problem for you. you might not have to remake another bios that some one made because they learned from your instructions.
I was just thinking that this should be possible - thanks for confirming. I haven't bricked a computer yet - but it's nice to know all might not be lost if it ever happens.
I actually used one of these for the first time recently! I bricked my Chromebook while flashing the stock firmware after having windows on it 😅. Pretty fun tool to mess around with and see how things work :)
@@kumaran627 what do you mean? I bricked it after flashing the wrong firmware when returning to ChromeOS, and used this to get the correct one on it. That Chromebook is still living lol
What is the point of this "ethics" if part of the firmware can be used in rare cases for a device of another model. The only downside for the manufacturer is if new functions were added to the old product, for example, NVME support to the old system board. Because of this, slightly fewer users will buy a new product with NVME support.
You actually get the right to use a copy of the firmware, not the firmware itself. That being said, I can also see why some people would try. Putting not encrypted firmware on an embedded device, and the SPI flash is also not included in the SOC. Its an open invitation at this point
I actually have one of these lying around, I once bought to fix a broken BIOS. Interesting to see what you can do with them. I had no idea how common these kind of chips where. Or that you could use the flashrom command line tool to interact with it. You always learn something new!
The only special thing about this product is the ZIF socket you're not even using for its purpose. For general SPI dumping you can use any old arduino or rpi lying around. Or if you get a more feature rich product such as bus pirate or tigard, you can do i2c, uart and others in addition to dumping SPI chips' memories.
Openwrt is awesome, I had a couple of routers that I didn't use, after discovering openwrt I could use for something useful, but unfortunately the routers only had 4mb of flash and 32mb of ram, so I modified the openwrt partition system for my device to fit inside an 16mb chip, so now I had more storage, but the ram was still an issue, so I flashed a custom bootloader that could work with different ram chips, and then I replaced the ram with a 128mb and now the router has the latest update and I'm able to use all the extra features of openwrt, this is only possible because openwrt is opensource, thank you all for that :D
I think I actually preferred the old camera style and video background (or lack thereof). Do like seeing new things though. Props for adding in pizzaz :)
I wish more new devices were still using SPI flash for more than eeprom config storage these days. TSOP isn’t too bad but requires more expensive readers and BGA just makes me want to cry.
Funfact: in some cases you don’t even need to use a flash reader to get the firmware. Most firms provide updated firmware’s that also often come in the .bin format and you could simply run these through binwalk. Even in the most up-to-date „secure“ version there are a lot of jucy CVEs waiting to be discovered. Ask me how I know lmao
1) Firmware is usually downloadable from manufacturer website , no need to dump it off the router 2) This programmer is not usually 3.3v logic level and requires quite finekey soldering 3) this programmer is massively unstable , writes , forget about it 4) bad drivers 5) don't cook your devices by reading it in circuit , it is a possibility , always desolder Wait till they findout how much you can do with just uart on some of these devices
This is the first time in my life I've ever heard anyone pronounce SPI as "SPY". But you're obviously a way superior low-level and embedded programmer than I am, so I'll follow your pronounciation from now on :D
@RaisalPradiptaBro a bunch of my fellow embedded engineers call it spy or spi interchangeably but then we also pronounce all the letters in the word sol-der in Australia 😁
I used one of these to unbrick my G75VX laptop in college after asus quoted me $900 to fix it after the laptop bricked when I told it to boot off the dvd drive lol
Love this device! Used it myself to remove the "whitelist" of acceptable wifi-adapters on a laptop years ago. It turned out it only accepted 4 devices in the whole world. It declined to boot if u used a good adapter that was not whitelisted. Damn i love that device. Have used it on alot of routers to bug-hunt aswell, and also decrypt firmware updates, since the key had to be stored in plaintext on the chip. :)
I used this exact tool to get the data from my BMW's 8 pin flashed onto a $50 replacement gauge cluster from eBay. Something that would have cost a trillion dollars at the dealer. Works like a charm.
I really like the Gov't suing people when people find out the Gov't has no security and does stuff like display your social security card in the html for some reason, gets your information stolen and then files charges for you finding it on the 'dark web', etc.
Wow thanks for that video! Just got mine ch341a and into ezviz camera to see what dodgy stuff (that I saw on wireshark) they are actually doing. Least to say private keys are handled on a plate and they even managed to ship C source code into production so I don't even need gidhra 🙃 It's amazing how security assumptions were defeated with an 8$ chinese tool. Thanks again!
I actually use this a lot with hardware hacking and tinkering cause its fun and i like that you can back up the whole device flash menaing i can mess with the firmware as much as i want and not having to worry about it never being able to function normally again or for it to become bricked forever. Also its fun to see 99% embedded devices running Linux and busybox. Alao often they ditch the gpl and dont comply which is lovely cause more fun trying to crack the software of a device and unveiling its secrets
To be fair anyone that can buy a standard USB and can write 1 line of code can break a computer with worm malware they created. It is more about knowing how it’s used so you can combat against it. The number one rule in ethical hacking is to believe the black hat is always 1 step ahead. So we are always playing catch up in security.
You read 16384 kB and you tried to write ~16777kB... that's bit more than just an extra character! Vim corrupted the file? You should have used hex editor. What happened to the device?
FYI the device wouldn't boot, as vim adds additional metadata about the text layout such as line breaks to the file, and you're right, he should have used hex editor.
I've reported many bugs in the past, never once got a bug bounty. Most I've been given is a thank you. Million dollar companies will not pay you. Don't waste your time helping them.
Because it is not a hacking tool. It is a hardware development tool that you can use for hacking. Similar that the hammer which is normally used to drive nails into wood when building can be used to break windows and possible doors during a burglary. You cannot make random things illegal because people start using them for illegal things.
you're saying "spy" instead of SPI so many times, maybe I'll get used to it in the end... never mind it's impossible for me to get used to it, but I tried 😅 Nice video though, great work! ☺️
Reverse engineering has been deemed to be completely legal if you do it in a clean room environment….basically disconnected from outside influence. You have to reverse engineer the firmware yourself without other input into how it’s done
Vim probably appended a newline after your file when you changed the string. By changing it to U-boo you would have changed the alignment of everything after so you probably would not have had it boot correctly.
I am not sure I buy the “open source is more secure” argument. After all you had people complaining about them, not fixing audio drivers for over a decade with problems that they knew existed in Linux. The first WORM that was ever written, was written by the son of an engineer who had access to the source code for the operating system. I knew guys who cracked games back in the 90s, but they had professional dev tools and games were only a few megabytes. Combing through even a few megabytes of an Assembly language for a platform you’re not familiar with is really hard. it’s way easier to find exploits in C source code.
literally just started playing with mine last night, pulled a BIOS off an old device, if you have a flipper you can also do this with the SPI memory application, raspi can do this as well, that's what I used back in my coreboot days. I found the soic-8 clip on this particular model to be much better quality than some of the other ones i've seen on amazon.
Isn't this just a chip reader/writer? Or is there something different about it? Been eyeing something like the TL866-3G, or is there something unique about this particular one?
big downside with these i find is if the board has more current draw then the chip or your usb port it wont read because it doesnt have enough current to turn the chip on -and- everything thats also connected to that 5v bus
I see a lot of people having a hard time understanding the deffinition of Hacking in the comments ... Forget the morality of making title clicbait away for algo/view purpous, this is still Hacking Hacking is the creative or unconventional use of tools, systems, or technologies to achieve a goal, often in ways they weren't originally intended to be used. It can involve exploring, modifying, or repurposing resources to solve problems, gain insights, or push boundaries. While hacking is often associated with computers, it can apply to anything where innovation or "thinking outside the box" comes into play.
Most of well developed electronics will not have an easy access flash storage for their code. Either they use an encrypted binary on their flash or they use internal flash, which is not that easy to access.
The title is misleading, as the tool makes reading firmware easier, but hunting bugs is a completely different matter which requires the source code or disassembling the binary.
"see's all the internet traffic in the house" Yes, the mostly -- almost entirely encrypted traffic.. Still not good. But I think it's important to not freak people out too much.
So I clicked on this video thinking that USB device would find BUGS as in covert listening devices in my home or AirBnB rental, and not to pull firmware off of a router. 😂
Just used one of these devices this weekend to flash a modified bios on my AsRock motherboard, to enable ReBar support. AsRock has there instant flash locked down to only accept there signature. So it does have valid uses, which like many things, can be twisted to do bad things. Also you can easily do this with a raspberry pi.
this isnt a hacking tool. its just a tool. i have several of these and have used them dozens of times to repair bricked devices, GPUs and more. if you use a screwdriver to remove your neighbor's door hinges and steal their stuff, it doesn't make a screwdriver a "burglary tool".. it just makes you a burglar. i can bypass all kinds of software security with a phone charger, pocket knife and a lighter. but it doesn't make it a hacking tool.. its still just a phone charger.
If the software is designed for security in an open source fashion, people being able to read it with a doodad wouldn't be a problem. Security through obstruction is ineffective.
10:30 if it uses GPL-like licensed parts, like linux, you actually need to be able to replace that bit. Of course, the root file system may contain other parts. And - if you report a bug, prepare to get sued.
The part where you use your genius to understand and your imagination to modify the firmware and do cool things, that's another meaning of "hacking" and it's fucking awesome

I tought that nothing can hurt my brain more than the pronouncing of SQL as "squeal" but here we are
Dude, my ears are literally bleeding from him pronouncing SPI as some Cold War Soviet fear
I keked every time you pronounced SPI as SPY
Openwrt is awesome, I had a couple of routers that I didn't use, after discovering openwrt I could use for something useful, but unfortunately the routers only had 4mb of flash and 32mb of ram, so I modified the openwrt partition system for my device to fit inside an 16mb chip, so now I had more storage, but the ram was still an issue, so I flashed a custom bootloader that could work with different ram chips, and then I replaced the ram with a 128mb and now the router has the latest update and I'm able to use all the extra features of openwrt, this is only possible because openwrt is opensource, thank you all for that :D
I wish I had the soldering skills to upgrade embedded RAM
Can you also rewrite the firmware in rust?
meh
Or in cpp;
1 trillion rust users triggered
@@Satoshic_ Me when I rewrite the firmware in pure Lambda Calculus 💀
Rust is too bloated.
We use Assembly now like a man who paid by hour.
No only JavaScript 😂
IT'S NOT SPY IT'S SPI
11:20 "with this device", as the spi programmer fades into the green screen. lol.
It's probably a stealthy device
@@wernerviehhauser94 stealth boy
@@vitto_pincharrata must be a prototype since it only makes itself and not the wearer invisible :-)
I think I actually preferred the old camera style and video background (or lack thereof).
Do like seeing new things though. Props for adding in pizzaz :)
im sorry but SPI is pronounced S.P.I. not SPY! The hell is that???
Don't know man, it's just heartbreaking 😭
I had same issue with SCSI pronounciation (skuzi or whatever) that i encountered some time ago. I was pronouncing it letter by letter...
+1, it's annoying
ah yes, because I want to say three distinct syllables instead of just saying "SPY". no thanks. shocking that somehow you still knew what I meant.
@@LowLevelTV what do you mean that language is about people understanding the meaning of others? 😱
Spy flash? I always pronounce it "Ess Pee Eye"
RUclips algorithm. That’s what I’m thinking. 😂
Its an acronym we absolutly should just say the three letter ... but You know people like to shortcut and make "new words"-_- lol
Please be consistent and call I.S.P. "ISP"!
I wish more new devices were still using SPI flash for more than eeprom config storage these days. TSOP isn’t too bad but requires more expensive readers and BGA just makes me want to cry.
There is a bug in the video at 11:18 (chroma key overflow).
Its a feature
@@KimYoungUn69but now it has been documented 😢
This is my first time checking out one of your videos. I enjoyed it and subscribed! It's funny, at first I thought you were Sheldon grown up. LOL
Please use manual focus if your camera is not keeping up :)
fun fact: you can use a multitool such as flipper zero to dump SPI memory chips too!
Funfact: in some cases you don’t even need to use a flash reader to get the firmware. Most firms provide updated firmware’s that also often come in the .bin format and you could simply run these through binwalk. Even in the most up-to-date „secure“ version there are a lot of jucy CVEs waiting to be discovered. Ask me how I know lmao
1) Firmware is usually downloadable from manufacturer website , no need to dump it off the router
2) This programmer is not usually 3.3v logic level and requires quite finekey soldering
3) this programmer is massively unstable , writes , forget about it
4) bad drivers
5) don't cook your devices by reading it in circuit , it is a possibility , always desolder
Wait till they findout how much you can do with just uart on some of these devices
Is finekey the word finicky? I’m just trying to understand. I think that’s what you meant. 🤷🏼♂️🤷🏼♂️🤷🏼♂️
you are the very first person I have ever heard call it 'spy' also, its not a hacking tool just like the screwdriver you opened that router with ;)
I used this to fix a expensive monitor that needed a chip reflashed after a power outage. So cool!
Better start backing up the firmware of all your devices
This is the first time in my life I've ever heard anyone pronounce SPI as "SPY".
But you're obviously a way superior low-level and embedded programmer than I am, so I'll follow your pronounciation from now on :D
@RaisalPradiptaBro a bunch of my fellow embedded engineers call it spy or spi interchangeably but then we also pronounce all the letters in the word sol-der in Australia 😁
I’m glad your name is no longer low level learning.
Thanks for finding your channel. big up man keep on going
I used one of these to unbrick my G75VX laptop in college after asus quoted me $900 to fix it after the laptop bricked when I told it to boot off the dvd drive lol
This tool can you let you recover a failed BIOS update using another PC
Love this device!
Used it myself to remove the "whitelist" of acceptable wifi-adapters on a laptop years ago. It turned out it only accepted 4 devices in the whole world. It declined to boot if u used a good adapter that was not whitelisted. Damn i love that device.
Have used it on alot of routers to bug-hunt aswell, and also decrypt firmware updates, since the key had to be stored in plaintext on the chip. :)
I also use CH341a to edit SFP I2C EEPROM information, very useful to change or crack SFP vendor lock!
I used this exact tool to get the data from my BMW's 8 pin flashed onto a $50 replacement gauge cluster from eBay. Something that would have cost a trillion dollars at the dealer. Works like a charm.
Good timing! Just as I m waiting for mine to ship.
I really like the Gov't suing people when people find out the Gov't has no security and does stuff like display your social security card in the html for some reason, gets your information stolen and then files charges for you finding it on the 'dark web', etc.
I have one! Bought to fix a samsung tv which died after power gone for half a second.
Love how when you mention "this device" for bug hunting, and hold it up... it mysteriously disappears! {ROFL}
Would love more hardware hacking content like this! Keep it up!
The device can also with the correct software read spi-nand chips.
Wow thanks for that video! Just got mine ch341a and into ezviz camera to see what dodgy stuff (that I saw on wireshark) they are actually doing. Least to say private keys are handled on a plate and they even managed to ship C source code into production so I don't even need gidhra 🙃 It's amazing how security assumptions were defeated with an 8$ chinese tool. Thanks again!
I think I found a bug in you video, lmao
ah yes the spy flash. my favorite type of flash. lol
I actually use this a lot with hardware hacking and tinkering cause its fun and i like that you can back up the whole device flash menaing i can mess with the firmware as much as i want and not having to worry about it never being able to function normally again or for it to become bricked forever.
Also its fun to see 99% embedded devices running Linux and busybox. Alao often they ditch the gpl and dont comply which is lovely cause more fun trying to crack the software of a device and unveiling its secrets
To be fair anyone that can buy a standard USB and can write 1 line of code can break a computer with worm malware they created. It is more about knowing how it’s used so you can combat against it. The number one rule in ethical hacking is to believe the black hat is always 1 step ahead. So we are always playing catch up in security.
what keyboard are you using? sounds really good
You read 16384 kB and you tried to write ~16777kB... that's bit more than just an extra character!
Vim corrupted the file? You should have used hex editor. What happened to the device?
FYI the device wouldn't boot, as vim adds additional metadata about the text layout such as line breaks to the file, and you're right, he should have used hex editor.
I'm with this thing on my hands right now
I've reported many bugs in the past, never once got a bug bounty. Most I've been given is a thank you. Million dollar companies will not pay you. Don't waste your time helping them.
9:27 -M for .. Matryoshka? The doll inside a doll inside a doll..
Guess that's how you can also label "recursive"
Because it is not a hacking tool. It is a hardware development tool that you can use for hacking. Similar that the hammer which is normally used to drive nails into wood when building can be used to break windows and possible doors during a burglary. You cannot make random things illegal because people start using them for illegal things.
you're saying "spy" instead of SPI so many times, maybe I'll get used to it in the end...
never mind it's impossible for me to get used to it, but I tried 😅
Nice video though, great work! ☺️
Reverse engineering has been deemed to be completely legal if you do it in a clean room environment….basically disconnected from outside influence. You have to reverse engineer the firmware yourself without other input into how it’s done
Because why on earth would it ever be ILLEGAL?
Vim probably appended a newline after your file when you changed the string. By changing it to U-boo you would have changed the alignment of everything after so you probably would not have had it boot correctly.
Was just going to post that :) Much safer to edit with a hex editor, not text editor
I am not sure I buy the “open source is more secure” argument.
After all you had people complaining about them, not fixing audio drivers for over a decade with problems that they knew existed in Linux.
The first WORM that was ever written, was written by the son of an engineer who had access to the source code for the operating system.
I knew guys who cracked games back in the 90s, but they had professional dev tools and games were only a few megabytes. Combing through even a few megabytes of an Assembly language for a platform you’re not familiar with is really hard. it’s way easier to find exploits in C source code.
This is like calling screwdrivers 'murder weapons'..
11:39 Something even cooler than this?! Say it ain't so!
literally just started playing with mine last night, pulled a BIOS off an old device, if you have a flipper you can also do this with the SPI memory application, raspi can do this as well, that's what I used back in my coreboot days. I found the soic-8 clip on this particular model to be much better quality than some of the other ones i've seen on amazon.
Isn't this just a chip reader/writer? Or is there something different about it? Been eyeing something like the TL866-3G, or is there something unique about this particular one?
big downside with these i find is if the board has more current draw then the chip or your usb port it wont read because it doesnt have enough current to turn the chip on -and- everything thats also connected to that 5v bus
I see a lot of people having a hard time understanding the deffinition of Hacking in the comments ... Forget the morality of making title clicbait away for algo/view purpous, this is still Hacking
Hacking is the creative or unconventional use of tools, systems, or technologies to achieve a goal, often in ways they weren't originally intended to be used. It can involve exploring, modifying, or repurposing resources to solve problems, gain insights, or push boundaries. While hacking is often associated with computers, it can apply to anything where innovation or "thinking outside the box" comes into play.
I used one of these to put Coreboot on my Thinkpad!
That backdrop is a green screen double whammy. Looks like someone plugged in a bad USB stick and got assimilated
Most of well developed electronics will not have an easy access flash storage for their code. Either they use an encrypted binary on their flash or they use internal flash, which is not that easy to access.
top video! got it during lockdown times for unbrickin BIOS'es on PC's.
The title is misleading, as the tool makes reading firmware easier, but hunting bugs is a completely different matter which requires the source code or disassembling the binary.
It's a spaaaaiiiii flash reader 🤣
Awesome 👍
Would love to see more hardware hacking videos 😊
No affiliate link to the device? Why?
because i am a moron
@@LowLevelTV add it to the description? I'd rather buy it and help you out then buy it and amazon get all the $$

Put focus on manual. You might also want to use a polarizer filter for reflection from glasses but might not work with multiple lights
"see's all the internet traffic in the house" Yes, the mostly -- almost entirely encrypted traffic.. Still not good. But I think it's important to not freak people out too much.
gotta love the hacker background
yes for you it is AI
False advertisement, it didn't catch any of the bugs in my room.
So I clicked on this video thinking that USB device would find BUGS as in covert listening devices in my home or AirBnB rental, and not to pull firmware off of a router. 😂
If your stuff's vulnerable, make it invulnerable
Just used one of these devices this weekend to flash a modified bios on my AsRock motherboard, to enable ReBar support. AsRock has there instant flash locked down to only accept there signature. So it does have valid uses, which like many things, can be twisted to do bad things. Also you can easily do this with a raspberry pi.
this isnt a hacking tool. its just a tool. i have several of these and have used them dozens of times to repair bricked devices, GPUs and more. if you use a screwdriver to remove your neighbor's door hinges and steal their stuff, it doesn't make a screwdriver a "burglary tool".. it just makes you a burglar.
i can bypass all kinds of software security with a phone charger, pocket knife and a lighter. but it doesn't make it a hacking tool.. its still just a phone charger.
It's legal as long as you're not using it for nefarious purposes.
You really don't know what you're missing till you go full Shalomie.
Dude this tool saves tons of laptops from ending up in the land fields so you should be respectful towards it.👀
Hey dude, would this process work on let's say an old Datto or Cisco router?
Ive never heard SPI called SPY
If the software is designed for security in an open source fashion, people being able to read it with a doodad wouldn't be a problem. Security through obstruction is ineffective.
Used this for Bios reflash. "Hacking" nah.
binwalk ftw
10:30 if it uses GPL-like licensed parts, like linux, you actually need to be able to replace that bit. Of course, the root file system may contain other parts. And - if you report a bug, prepare to get sued.
Hey I just wanted to thank you for sharing your knowledge of computers you are very good teacher and you're well spoken individual
What is the 'hacking' part?
The part where you use your genius to understand and your imagination to modify the firmware and do cool things, that's another meaning of "hacking" and it's fucking awesome
@@dutchlegend007 i guess it would kinda be considered "hardware hacking". If you find a default password or some vulnerabilities in the routers firmware etc.
