    Machine Shutdown Security Tool

    Knock down your server into full disk encryption when a user attempts to physically attack your hardware via USB. This project seeks to provide a quick any easy low overhead solution that will shut your computer down to trigger your full disk encryption before an unsophisticated adversary has time to extract sensitive data. News: Alpha 0.04 Hotfix Update - Passwords now work! - Successfully tested against USB Rubber Ducky! This release I worked on building out a class that can be used to start offensive attacks on the target USB. Two options have been enabled for this release, the ability gather a log of all files on the incoming device & the ability to calculate the SHA1 of the incoming drive's files. I have some really cool things planned for upcoming releases that will hopefully include user defined file injection onto suspect USB. For now, if you enable logging files will be dropped into C:\ Upcoming: - Better Passwords - User Defined Counter Attacks

    2Pix
    2Pix integrates with Windows to allow you to easily encrypt and hide files in bitmap images, a process called steganography (not to be confused with stenography). Data is stored in the low-order bits of each pixel of an image, so the file is completely hidden from view. Version 1.1 now provides plausible deniability because no unencrypted signature is stored in the image header. It should be impossible to prove an image contains a hidden file (if you use a strong password and only use 1 or 2 bits per pixel component). NOTE: This project has been moved to Google Code. http://code.google.com/p/2pix-steganography
