To destroy a HD, just take the shiny disc inside and put it to a grinder, and grind it down to the metal ring. Easy (:

I never tried it, but I also heard microwaving it would work, not sure though.

But I was wondering something. Is re-writing something the same, or different, than if you were to simply delete something? As in, if you had 'bankinfo.wps', and created another file called 'bankinfo.wps', and then replaced the first 'bankinfo.wps' with the one you just created, is it the same as deleting it, or different?

Or what if you simply open 'bankinfo.wps' and delete all of the text, and save it? Is all of the history of the file saved in it internally somehow?

when DOS was still the dominant program operating windows....yes. Files were set locations for data, and rewriting it would ultimatly delete what was changed leaving the new information. NOW your computer tracks just about everything you do, so you can actually retrieve alot of info you recently deleted or rewrote.

Microwaving would destroy it if left in for long enough....also a very powerful magnet or electric current would do it also. Harddrives store info the same way cassette tapes do, they magnatize the media aligning the particles. That way a reading head can view the information, in the case of harddrives, it will read a 0 or 1 in each location on the disc.

Virus scanning software can actually elevate the privileges of a virus. As a virus scanner has to be ran from ring 0 or kernel mode etc to be effective. At the same time, a virus that only has user or ring 3 access can wait for easily to predict instructions to pass through the processor with kernel level access and hijack them. This is actually rather easy -shrugs-

With that said, a smart exploiter who has obtained limited access to the processor will simply bog it down goading the user into taking action at a higher access level. Once they gain real access, monitoring and controlling the system does not need to bog it down for long durations at a time, as did the goading process (depending on what they are trying to achieve and how aggressive they are). This tactic doesn't tend to be common knowledge from what I've seen... even among tech-savvy computer users/coders like AceoStar and Falaris.

As someone that does penetration testing and security consulting, this is something I've seen frequently and learned to watch for closely

There is a huge market for virus scanning software and much of it is inaccurate -- not to say that they do not provide some benefits.

The only way to really scan for viruses is to dead the drive and even the memory. You kill all power to the drive and the memory and you mount them from a secondary system and scan them from the secondary system. This way there are no processes running on the system you are trying to analyze.

Conceptually, trying to scan an operating system that is suspected to be compromised with the very same operating system that may be compromised and expecting it to give you accurate results is naive.

There are various other levels beyond the operating system which can also be compromised. Killing the system, mounting it, then scanning it from a secondary system before resurrection takes care of most of these issues.

That is how the Department of Defense, National Security Agency, and various other organizations are required to handle these situations -- at the least.


It can be fun, more effective, and educational to let them think they've exploited you.


Enjoy, lol.



You sir are a [content removed]ing genius. Thank you for posting this!


PS. someone is checking up on you, just thought you should know.

Seriously, I think interstate is a moron or at least some type of crazy person. He obviously has no idea what he is talking about.
