_________ SWAT MAGAZINE ISSUE NINETEEN: JULY 1999 __________ / \___________________________________________/ \ / When Paranoia strikes! \ / By -=The Firestarter=- \ ----------------------------------------------------------------------- From time to time we can all be a little paranoid, there's nothing wrong with that, well if it can be justified then there's nothing wrong with it. So when you get tipped off that certain Government people have taken more than a little interest in you and want a nice little chat about some hack on a server that caused the downfall of a small country, you might think that perhaps you should cover some of your tracks and hide/destroy/encrypt a lot of stuff. We'll start with your computer, ok you'll most likely have a load of disks about the place, so get all them and copy the contents over onto your hard drive (that is if the contents are a little dodgy), once that's compleated it's time to wipe the disks, wiping disks so that no possible means of recovery will work is very simple indeed, all you need to use is a can of lighter fluid and a match. Next up is the hard drive, i used to use PGP straight out to encrypt stuff, it works very well, the only draw back is that it takes fucking ages to encrypt and decrypt, then you've got loads of encrypted files and decrypted files all over your hard drive, so i now use PGPDisk, since it comes free with PGP 6.0.2i. Ok simple create disk big enough to hold all of your files (about a gigabyte is probably enough), now move all of the files from your hard drive into the PGPDisk volume. Just about done, make sure that you have everything in there, now unmount the PGPDisk volume and use your standard PGP key to encrypt the volume. Done that? hope you remembered to wipe the original. Next up grab a copy of Scramdisk (http://www.hertreg.ac.uk/ss) and use it's Wipe option to clear all of the freespace on your hard drive, now this takes a long time, so make sure that you have got everything into that PGPDisk volume that you need to. Ok time for the wiping, The standard for safely wiping anything is to pass it 7 times, but since we're paranoid, we'll wipe it 9. So just before you go to bed at night, set it to wipe freespace and use 9 passes. Now if you have a huge 13Gb hard drive, you'll probably have to leave your computer on for the rest of the next day as well. If you don't really have all that much time, then i came up with a way that isn't as secure as a 9 pass wipe, but it should overwrite most of the stuff on your hard drive enough for a 5 pass wipe to be efficent. To start off with grab yourself any CD ripper and a CD. Rip the tracks into .wav's and dump them on the hard drive, that should deal with about 600mb (or more) of hard drive space, now use any encryption program to cipher the .wav's, use PGP or anything to do it. Once they've been encrypted enough time. Repeat the process by using copy and paste to get as much hard drive space full as you can. Once again, encrypt the files, then wipe them using PGP, donce that? now use Scramdisk to wipe the free space. Plain and simple. Now we'll deal with papers and stuff, ok dealing with papers is simple, anyone can dump them in a bin and then firebomb it. But just how many papers do you have? unless your extreamly organised you'll have trouble finding every single bit of paper. Wouldn't you hate to be convicted on a small post-it note that fell down the side of your bed with the login and password of Bill Gate's pop3 account on it? So it's time for a spring clean, get yourself a few cardboard boxes and begin a mass sort out, place anything that is not dodgy into one card- board box, and everything that is dodgy into the other cardboard boxes. Make sure that you go though EVERY thing, remember they'll find things that you thought you threw out months ago (hell i found a notebook with loads of confrence ID's, PBX numbers etc in a notebook back from when i was in Darkcyde, and i'd lost that for nearly a year). I dunno where you keep all of your papers and stuff like that, but if you go thought every single thing in yout room then you'll be alright. If you don't know what it is, then mark it dodgy. All sorted? Bonfire time i think. Simply use your choice of volatile chemical concoxtion to get rid of all that evidence in the confort of your back garden (or where ever you choose to drive your stuff to and then torch it). So you've now got rid of most of the stuff, anything that you want to keep should be placed in a locked box and taken to a friends house, (prefreably one that lives more that 50 miles away) and left there for a while. I think that should keep most of you safe, but if they turn up unannouced then you could very well be fucked (unless like me you like to keep everything "nice and tidy" in the event of an unplanned visit by the gestapo).
