Pentoo
Pentoo is a Live CD and Live USB designed for penetration testing and security assessment. Based on Gentoo Linux, Pentoo is provided both as 32 and 64-bit installable live CD. Pentoo is also available as an overlay for an existing Gentoo installation. It features packet injection patched Wi-Fi drivers, GPGPU cracking software, and many tools for penetration testing and security assessment.
