network and wifi hiding...
Obtains a laptop… untracable.
Drive around and find a nice unprotected signal… (more miles from your home the better)
Use some proxies, hack your heart out, dump the laptop.
If they find you after that i will eat my hat.
Make sure that hacks worth it tho ^^
Though unless your doing somthing highly illigal, just use a proxie.
Should surfice.
Do not use TOR! Not only can it be beaten with java and flash plugins, there are also rogue nodes, and if you happen to pass through two or more then all of your communication is comprimised. And you never know who is listening.
Get yours self a private machine somewhere on the planet, one that does not keep logs… And use a vpn/remote desktop with good encryption. Even that should be considered a disposable asset, and if its not, your hack isnt worth the trouble.
If your taking down some noob website, you hardly need even bother with a proxy…
In Most cases a will do just fine like they said. If you want to have your wifi "signal" not picked up, buy some gear that runs on frequencies standard in another country. Not 100% foolproof, but less likely to be found by someone wanting to get into you via wifi. IF they pass through a network then it doesnt even matter because the other frequency ap would just translate to tcp/ip over a wired network. But if you really wanna be hidden… steal a internet phone and use it on your laptop. There are ways to use a phone for internet access nowadays;)
A lot more portable than wifi hehe.
