The hacktivist collective Anonymous launched an attack on various Swedish government and banking websites in the name of The Pirate Bay and Wikileaks editor Julian Assange.

In the Youtube video above, organizers pledged to "launch major attacks on several vital portals that represent Swedish society" in the next few days.

The effort, dubbed #OpPRQ #OpPirateBay, will be "the biggest thing ever done in anonymous history," the video claimed. It requested the help of Anonymous supporters, likely to conduct distributed denial of service (DDoS) attacks.

"Free Assange. Free internet. Expect us," the video concluded.

The Wall Street Journal today reported that attacks took down the websites for the Swedish Security Service, the Swedish Prosecutors' Office, and Sweden's central bank. All but the Swedish Security Service appear to now be back online.
