Fresh off confrontations with Mexican drug gangs and Israeli security forces, the Anonymous hacktivist collective seems to have found a new target: Egypt's Muslim Brotherhood.

"The Muslim Brotherhood has become a threat to the revolution Egyptians had fought for, some with their lives," the usual Anonymous mechanized voice states in a YouTube video posted Monday (Nov. 7). "They seek to destroy the sovereignty of the people of Egypt as well as other nations including the United States."

The video dubs the operation "OpBrotherhood" and promises a takedown of the Muslim Brotherhood's main website, Ikhwan Online, Friday at 6 p.m. Greenwich Mean Time (1 p.m. ET). Presumably, the site would be the target of a distributed denial-of-service (DDoS) attack.

The video posting was first reported by Michael Stone on Examiner.com.
