Hacker group Anonymous delivered another blow on the Federal Bureau of Investigation (FBI) by taking down the Web site of the Dayton Ohio Chapter of InfraGard Friday.

InfraGard is a private non-profit organization serving as a public-private partnership between the U.S. businesses and the FBI. However, Anonymous has its own definition - the sinister alliance between law enforcement, corporations, and white hat wannabees, the group wrote in a note it posted onto the homepage of InfraGard Dayton, Ohio.

#FFF [LAST HACK] FBI-INFRAGARD ROOTED AGAIN. ONE MORE TIME. FOR THE LULZ. infragard.dayton.oh.us #Anonymous #AntiSec #LulzSec #OWS, @AnonymousIRC tweeted Friday.

At the time of reporting, the homepage of the Dayton Ohio Chapter of InfraGard's Web site was showing a message by the hacker group in red.

Anonymous wipes another shitty InfraGard site off the Internet on #F**KFBIFRIDAY, the message read.

We broke into their webserver, perused their assorted presentation materials, and finally deleted everything and vandalized their website so we can boost our zone-h rankings, the message stated.

You think your 'advanced commercial malware' research and your 'digital forensics first response' powerpoints can really withstand the hurricane of hellfire and 0days we got planned for yall?! ACTA? Cyber Security Act of 2012? Do u really want 2 fuq with us?!?!? Follow @AnoynmousIRC, haters.

The message by the hackers also carried a video of the rap song Gangsta's Paradise by Coolio featuring L.V. from the movie Dangerous Minds (1995).

In June last year, the LulzSec hacker group hacked the Atlanta chapter of InfraGard. The group reportedly defaced the Web site and leaked its user database in response to the Obama administration's decision to treat hacking as an act of war.
