BootRoot

eEye BootRoot is a project presented at Black Hat USA 2005 by researchers Derek Soeder and Ryan Permeh, as an exploration of technology that custom boot sector code can use to subvert the Windows kernel as it loads. The eEye BootRootKit is a boot sector-based NDIS backdoor that demonstrates the implementation of this technology.

Because BootRoot is detected and auto-quarantined by most anti-virus installations, the .zip is password protected with 'eeye' as the password.
