Hacker Defender Author (Holy Father) Kills Stealth Project

The creator of Hacker Defender, the well-known rootkit, has pulled the plug on his antidetection service. Holy_father's reason: He doesn't feel he has anything new to offer. Hacker Defender has long been a weapon of choice for those seeking to attack remote Windows NT/XP/2000/2003 systems without permission. Rootkits covertly patch the operating system, changing it forever... or at least, till you reformat your hard drive. While Hacker Defender was famous among security professionals, another rootkit got more attention among end-users: The rootkit Sony-BMG embedded in unsuspecting customers' music CDs. Untold damage resulted... to both users' computer systems and Sony-BMG's reputation. As the designer of one of the first user-mode rootkits, holy_father sought to constantly remind the world that the Windows operating system is woefully unprotected.
