dban is a bit overkill if you just want to wipe the MBR and destroy data on a drive. A single zero pass would be fine
Takes a hell of a lot less time!
It does have that option. I used the so called "least secure" option of a zero pass on a 100 gb HD and it took 2 hours max. Some of the erase options dban offers are insane.
Just use a linux liveCD and run:DISCLAIMER: DO NOT "test" THESE COMMANDS ON A SYSTEM YOU DON'T WANT TO DESTROY!!!!!
dd if=/dev/zero of=/dev/sdX
where X is the device
Did this to a 1TB drive not long ago, took maybe 4 hours... maybe a little more.
You could also do a (psuedo)random data write with
dd if=/dev/urandom of=/dev/sda
Since we were talking about these rootkit viruses within the MBR.. If you just wanted to kill the MBR:
dd if=/dev/null of=/dev/sdX bs=446 count=1
and to remove both the MBR and the partition table (which you'd have to rebuild if you wanted to use the partitions again!):
dd if=/dev/null of=/dev/sdX bs=512 count=1DISCLAIMER: DO NOT "test" THESE COMMANDS ON A SYSTEM YOU DON'T WANT TO DESTROY!!!!!
I'd imagine these rootkits would get back into the MBR as soon as windows boots again, so I don't think this would fix it without at least killing the processes/services which it depends on in windows.
Interesting virus.. very nasty
I'm gonna do some checking on all my systems. Guess its perfectly possible that poeple are losing their wallets to this rootkit/botnet - they could easily send a command to the infected machines to search for wallet.dat and send email/send it somewhere. Obviously I'm just guessing! But AFAIK you could end up infected just by visiting the wrong website :/
Dude, I hate you so much! It totally wiped out my computer!
