Cult of the Dead Cow [cDc] Hacker Group

Cult of the Dead Cow, also known as cDc or cDc Communications, is a computer hacker and DIY media organization founded in 1984 in Lubbock, Texas. The group maintains a weblog on its site, also titled "Cult of the Dead Cow". New media are released first through the blog, which also features thoughts and opinions of the group's members.

To further the Cult's stated goal of "Global Domination Through Media Saturation," over the years cDc members have granted interviews to major newspapers, print magazines, online news sites, and international television news programs.

The cDc has released several tools, for both hackers/system administrators and for the general public. Many of these are related to computer security and are sometimes dubbed "hacker tools".

The Automated Prayer Project
The Automated Prayer Project, written by Javaman, is "a VT420 connected to a Sun Ultra5 via a serial cable which displays the output of a continuously running program. The signaling rate is limited to 9600 baud. The program itself cycles through the Rosary, displaying a new individual prayer once every thirty seconds. Each individual prayer is then sent out via UDP to a random machine on the Internet on a random port."

Back Orifice
Back Orifice (often shortened to BO) is a computer program designed for remote system administration. It enables a user to control a computer running Microsoft Windows operating system from a remote location. The name is a pun on Microsoft BackOffice Server software. The program debuted at DEF CON 6 on August 1, 1998. It was the brainchild of Sir Dystic. According to the group, its purpose was to demonstrate the lack of security in Microsoft's operating system Windows 98.
