It surprised me how hard it is to destroy a hard drive with a magnet. With my school laptop I took a massive neodymium cube magnet and swiped it over the hard drive while it was running it made some clicking sounds but besides that the computer kept going no matter what I tried. The only difference I noticed was the hdd was noisy and it took like an extra minute to boot windows
Regarding private messages being not exactly private, that may be true for many standard services (think Reddit, or Discord) but there are actually services like Signal that use end-to-end encryption so that they can't see your data, and nobody else can either except the intended recipient and you (encrypted on your phone, decrypted on theirs.)
I actually have a video on how end-to-end encryption can be hacked using the "man in the middle" method. Check it out ruclips.net/video/nocM5vMwmLk/видео.html
There was some truth to halt and catch fire in the early days. Before protection circuits you could write code that if executed would cause hardware damage. From burning up crts yes smoke and a small fire if left alone to crashing floppy drive heads and hard disks. Some modern hardware can be ruined by tweaking certain bios settings and code forcing them to hold. But it wouldn't be instant and you'd be going well out of your way to harm the machine. but the stuff from the late 70s and early 80s its true. Halt and catch fire is real.
The new on the fly overclocking features some boards now offer also have the ability if code forced to run bad settings over time to cause hardware damage. Those boards manufacturers also warn you multiple times about the risks if you leave the runs well stock and safe settings. So if you do it by hand or write a program either way you're only doing what the manufacturer admits it can do already.
You can’t steal someone else’s crypto wallet, but you can use other ways to access their account: keyloggers, social engineering, RATs, brute force attacks or using passwords that person used in other pages like Facebook or Twitter. Those pages usually have 3 step autentication, so the best option is either social engineering or hacking their email account.
Right, but that works with anything, including bank accounts, this is not limited to crypto only. So it's not crypto's fault that people fail to follow simple security rules.
er wait. ive got a crypto wallet thats stored locally for some coins I mined while experimenting. Its literally a file so why couldnt someone copy it? Its useless without a decryption key but the file itself isn't protected against duplication. Do other offline/local crypto wallets not literally store information inside one or more files which is the wallet?
no, a virus cannot set your PC on fire under normal circumstances. Your PC has several safeguards, such as thermal throttling and temp limits. your PC will shut down long before a fire can start.
What about quantum computers (for the first question), everything will be cracked no matter how secure it is, it's just a matter of time. and what about the stuxnet virus (for the third)???
Thing is, we don't know exactly what quantum computers will be and how they might be actually used for bruteforcing. I'm sure before they actually come about, cryptocurrency algorithms will be updated to reflect the changes.
On socket 7 atleast systems you could turn off overheat protection and stop the fan via bios calls. If left in this state for very long you could damage the cpu.
@@RonMattinowith the old socket 7 rigs since most ran win9x and weren't really a seperate os from DOS you could use the standard bios interrupts along with direct access via asm. win9x didnt really seperate the hardware from you like NT based OSEs try to do. On an NT system if you're fluent in asm id take that route. Otherwise use the API calls windows provides for the windows bios update software to work.
heh a virus can literally overwrite your firmware/bios and cause your device to not boot and no it isnt as simple as being a specific drive or computer, manufacturers tend to have common interfaces that updates take and 5 different companies will have the same ufei updater that runs right inside windows
Motherboard manufacturers use digitally signed firmware these days, so attack on bios chips/firmware is not possible. Unless the user does it themselves. ;)
A virus isnt necessary for that. Besides things have come a long ways since Klez was around infecting rigs and wrecking firmware of compatible machines. may its author who passed very young RIP.
Viruses cannot make your computer catch fire but i can. Run
Awh hell nah 💀

That's impressive, Jon! BTW, Merry XMAS 🎄🎄
Thanks, you too!

a virus can remove it and kill ur cpu

How do you make a bios call from Windows? ;)

Another underrated channel) thank you for your videos mate 😊 wish you 1000000 subs))
Thanks a ton!
Hello, can you show about soldering 🥰
Yep, we're gonna have a big video dedicated to soldering! Coming up! ;)
Your videos are lot of information and knowledge....❤😎
Love from india
i'm really stupid and made a comment before actually watching the video T-T sorry
