An earlier series of attacks targeted the blog of Michelle Malkin, who led a movement among bloggers to mirror the controversial cartoons of the Prophet Mohammad that initially appeared in a Danish magazine. The attacks began Feb. 15, and escalated on Feb. 23, when an attack from a botnet in Turkey forced Malkin to post on the Pajamas Media weblog until her main site was available again.

The attacks on Malkin’s blog appear to be part of a broader pattern of hacker activism targeting sites that have featured the cartoons, including the defacement of hundreds of sites as well as denial of service attacks.
