Political hacker takes credit for Wikileaks DDoS attack

The attack began at approximately 10 a.m. on Sunday when traffic to one of Wikileak's primary hosting providers significantly jumped by two to four gigabytes per second, Craig Labovitz, chief scientist for security firm Arbor Networks, wrote in a blog post Monday.

Hacker calling himself Jester

A hacker calling himself "Jester" and using the Twitter handle "th3j35t3r" took credit for the attack, which made the Wikileaks site inaccessible for several hours.

After the attack began, Wikileaks redirected DNS configurations from its Swedish hosting provider to sites hosted by Amazon's Elastic Cloud Computing (EC2) service in Ireland and later the United States, according to researchers. Despite the attack, Wikileaks began publishing the cables at cablegate.wikileaks.org on Sunday.
