From past experience i`ve found the computer would either lock up or start rebooting if it got too hot. I`m sure anyone with a bit of computer knowledge would realise soemthing was seriously wrong before it completely fried the CPU.

GORE, a lot of modern monitors will shutoff/cut the signal if the refresh rates reach a certain point, however it will work on some of them out there.
I think what can be gathered from the discussion is that hardware is so heterogenous, that a hardware damaging virus is unlikely, and of course even if there was one that could exploit hardware universally, it wouldn't be very succesful in spreading as it "destroys its host" thus ending its life cycle.
I was reading a theoretical paper a while back that showed how certain pulses sent over a standard ethernet wire can harm/destroy any hardware connected to it. This included routers, switches, PCs, hubs, etc.
They had been able to test this theory in a lab, but so far have only been able to get the pulses to travel over cable that was less than 50 ft in length. I'll see if I can dig that theory/study up as it was fairly interesting.
I would guess if you hooked an ethernet cable up to a decent power supply you could "pulse" some voltage and damage a switch or router.
Hell yeah it would RoadClosed.......however, the thread is about remote hardware damage. We could come up with a million and one ways to destroy hardware with physical access to a box....that would be an interesting thread....peanut butter and jelly for your CD-ROM anyone? ;)
Lol I was inovating on the post above mine, but now that I think about it - my switch is in the next building so that would be remote! :) Hmm, makes me want to google something like "ethernet surge protection" which pulls up something like this.
Ok that thread seems to have got a lot of interest...the interesting thing is that finally there are a number of ways to harm remotely a computer...maybe it should be a good idea to make a tut about this subject... i dont have the time now (exams) but i will try it after i finish... also i have to mention sth very interesting that was written by SSJVegeta-Se: ('This is a bit off-topic, but something I found very interesting was suggested in the .hack series of games - they called it "Deadly Flash" - a fictional computer virus that caused physical harm to the USER by flashing their screen with seizure-inducing colours... scary thought, since it's quite possible with today's technology.)Can that really happen????? That seems more scary!!!
Actually, if someone has epilepsy.. some wavelengths/frequencys of lights can trigger seizures.Quote:

Not sure how this would be implemented... but I'm sure it's entirely possible.. if not somethig that's been done already. I seem to remember some years ago heairng reports of seizures from a television show/ad....
i dont have any links but i remember back in the early 90's of a virus that was being propagated through bad disks... it changed the refresh rate on your video card to some insane random and dynamic settings that it fried the monitor... but i never saw this in person, just read about it in the newsgroups a long time ago ;)
hrm, I still haven't found that link... I know I have it somewhere I just can't remember what machine it was on :)
Anyway, this didn't involve an electrical pulse of any sorts... or at least not like hooking a power supply up to a ethernet cable. This was creating a pulse from a PC through the ethernet cable that could harm/destroy anything that was attached to that cable. They were working through technical difficulties of length of cable the last I saw.
I could swear it was somewhere like MIT or CIT that was doing this research.
anyway, I'm off to try to locate that white paper.
