Three new laws of robotics:
1. Drink all the booze
2. Hack all the things
3. Kill all the humans

Installation of Kill All The Humans:

1. Become root, none of that sudo shit.
2. cpan
- install POE
3. make install
4. Make sure the script starts/stops on boot and shutdown.
- backtrack linux: update-rc.d killallthehumans defaults
5. Remove any USB drives that may be connected
6. Start the script for the first time
/etc/init.d/killallthehumans start
7. Plug in a USB drive and wait a moment for shadow.gpg to be copied over
- Private key is located in /etc/killallthehumans/humans.key

NOTE: This drive will now be recognized at /mnt/shadow instead of the
typical /media/volume

    Hi hak5 crew
    I really enjoy, love the show bc’se that’s awesome since I’m learning linux directly by practice inspite of doing theory without ./make &
    for real world.
    I’m using backtrack5 as my linux world to turn all my linux dreams into real with you Darren and Shannon;
    Great thnx a lot, keep on doing good job.

    I asked Sir Darren last year to cpmpress the HD files but he replied that there are other small formats available also: I understund but I only watch hak5 on HD even with my little bandwidth as it’s awesome with high quality so please try to compress them only for 48 hours and delete them (I understund the hard dsik space therre @ hakhouse);

    This two factor authentication isn’t practical compared to other options available. Google-Authenticator has a PAM module that is very easy to install and setup. Yubikeys also work via a PAM module. This is a quick install and 1 line edit then two factor authentication is up and running!

    Hi, folks.

    Thanks for great stuff. It brings more fun in out lifes. =)
    My tip is to use “shared memory” in /dev/shm as storage for decrypted shadow file. I think it’s more simple in compare to making tmpfs partition in RAM. =)

  • Possible solution, any thoughts:

    Daemon:

    * Library Password Token (.h file for c)
    * Randomly Generated – put in #define tokenpass 83adf983n2nfaz8fo9n3f (32+ bit long)

    Place USB stick in:
    Load daemon, on first load: Regenerate all usernames and passwords
    *system accounts auto generate*
    Daemon creates splits new shadow file hash, puts half on usb and encrypts usb with tokenpass, it can also format the hash lines randomly to prevent guessing which half hash goes to which account.
    Daemon then only prints its half of the hash, on the encrypted system with a identifier to read random hash order.
