A virus that overclocks - Page 4

post #31 of 38
Yes it's possible. In 2006, i had one of those virus and i don't know how it work and how it came in but it dit. He OCed ( i think) the cpu enough to make CPU and mobo burn. At this time i was a noob in hardware so i didn't pay atention to it and i was planing to change soon... But 2 years ago i searched about this and there is some kind of really dangerous ( the most dangerous ever i think for a personal comp) virus wich can do it.

I hope anyone would get it and NO i wasn't watching porn or whatever. That probably came with a movie torrent... Pay attention to what you download

I really hope i'm wrong and it was related to electricity...


Note: sorry if my grammar or whatever is horrible, i'm french canadian ^^

I know I've head of viruses that could make your hard drives spin so fast they catch on fire, but this was years ago.
post #35 of 38
Possible? Yes. Practical? Not wide spread.
Something as such (like a LARGE percentage of professional malware) would be targetted.

Just FYI, I can guarantee Billy did not catch such a virus. And Shadow is wrong as well. There is a physical limit to drives.. fire is a far cry.
And yes, this would be a VIRUS. An ACTUAL virus. The type that accounts for < 3% of actual malware, and a MBR-like appender is even more rare.

If you know anything about the security scene, then you already know this. If you know where to look, then there are PUBLIC files on BIOS infection and similar methods for more persistent and silent malware.

The only way I think it's possible is when you flash a BIOS using .exe. The bad bios could have code that the program thinks is safe..

Another one is running a flasher in DOS mode to flash a GPU (lets say). You have no idea if the BIOS is bad, flash. Reboot and bam

It is possible that a program could flash the BIOS from the OS, and have the BIOS load it's own custom code to overclock and burn the CPU on next boot (the program could reboot the computer). However, a DualBIOS would render such an attack useless, and the attack would be extremely hardware specific. This (theoretical, of course) attack would render the defense of a locked down BIOS useless, because the flashing could load an entirely new, unlocked one.

The above attack is possible, but highly theoretical. I doubt an attack like that would ever work, because it is so hardware specific: BIOS code, BIOS versions, motherboard, CPU, and the OS would all change the attack code.
