It's simple, really.
I have never shared this before might make a thread on it, PM me if I should.....
1) Buy a laptop from craigslist or other local site like that, so you won't be a record if you buy a laptop in a store.
2) After you but a laptop, run DBAN's autonuke feature and install the OS of your choice.
3) Drive/walk to some residence and download TMAC(if on Windows) to spoof your MAC adress.
4) Now go to a different wifi hotspot and download the tools you will need while your mac is spoofed.
[Tools include hacking OS, VPNs, hash crackers, ebooks, etc.]
5) Encrypt your harddrive with truecrypt setting a password as long as you can remember.
[I found a good technique is to walk around your town, every other street block mentally note an item, do this until you have ~5 items.
For example: CatBenchTrainCoffeeJar. Now add numbers to the end of each word. so Cat1Bench2Train3Coffee4Jar5. If you want more security, replace characters, like @ instead of a.]
6) With your encrypted hard drive, use a keyfile stored on a USB.
[Here would be the procedure if you are going out to hack.
You leave your house, after unlocking your HD with the keyfile.
Now, leave the keyfile USB at your house(hidden) so if you or your laptop is intercepted they won't have the keyfile.]
7) Get a screen-guard like what banks use so you can't see what is on your screen from an angle to prevent snoopy people/cameras.
8. Put a band-aid over your webcam in case of virus your face is hidden.
9) Set your BIOS to require a complex password and to NOT boot from USB in first order.
Now when hacking:
1) Spoof your wireless cards MAC so no trace is left on the router/modem you are using to hack.
2) Once you spoofed your wireless cards MAC< also spoof your PCs.
3) Hop behind a VPN (No logs), then connect to a SSH tunnel, then setup your applications to run through that tunnel as well.(Tor + SSH +VPN is also an option.)
4) After every hack run CCleaner with all options enabled and make sure it is overwriting (3-pass).
5) Wipe your free space (3-pass.)
Uhhh yeah, that is what I could think of off the top of my head, PM me if you want to know more, I hope this helps you.
