The Associated Press reports:
Earlier Friday, Anonymous claimed credit for defacing the website of a Dayton, Ohio-based chapter of Infragard, a public-private partnership for critical infrastructure protection sponsored by the FBI. The group's site was replaced by a video of Coolio's 1995 rap hit, "Gangsta's Paradise."
The FBI declined to comment on that attack.
Anonymous, an amorphous collection of activists and Internet mischief-makers, has increasingly focused its energy on military, police and security companies in recent months. Among its most spectacular coups: The interception of a conference call between FBI and Scotland Yard cyber-investigators working to track them down.
