A hardware supported hypervisor originally built for malware analysis. Features: Linux VM introspection, minimal detectability, small (~150KB), simple, and well documented. Can be used for other purposes. Support for Intel-VT & Windows coming soon.
Strokey is a small hardware keyboard logger saving all keystrokes into an EEPROM memory for later investigation. The device may get attached to any PS/2-keyboard by intercepting the cable, or get placed directly inside for maximum invisibility.
