Notorious hacker Fluffi Bunni has struck again, shaming two security sites in the last week - the high-profile SecurityFocus.com and lesser known Synnergy.net.

The Bunni has been credited with just 16 defacements since he first appeared on the scene last summer, but has some high-profile antics under his belt. Victims include security sites the Sans Institute and Attrition, McDonalds, and the hacker everyone loves to hate, Kimble.

The Bunni is known for his mocking defacements and the most recent hits were no different. "You think you know? You have no idea!" he taunted on the SecurityFocus site.

A seemingly elusive hacker, the Fluffi Bunni seems to only take on Linux, Solaris and BSD boxes and never leaves any sort of contact details like some of the more attention-hungry defacers.

However, from evidence gathered from the screengrabs and digital photos used in his defacements, we may be able draw some tenuous assumptions about this character. He is possibly Swedish, drinks Stella Artois, smokes and has a collection of pink fluffy rabbits. So be on the lookout.
