In response to yesterday's arrests of five LulzSec hackers, Anonymous has defaced Panda Security's PandaLabs Web site.

"In a characteristically defiant message posted on PandaLabs' hacked homepage, Anonymous taunted the former LulzSec leader Sabu for helping the FBI nab the hackers, and vowed to carry on its hacktivist campaign regardless of the setback," writes Computerworld's Jaikumar Vijayan.

"The attackers also posted what seemed to be the login credentials of numerous Panda Labs employees on the defaced homepage," Vijayan writes. "They noted that the attack on the security firm's site was in retaliation for Panda's alleged role in helping law enforcement crack down on members of the hacking collective."
