Anonymous claims hack on Swedish websites

Hackers have struck at least two Swedish government-affiliated websites, shutting down one of them in a denial-of-service attack and leaving links to profane messages on the other.

The attacks come just days after police on Monday raided a Stockholm-based webhosting company, PRQ, and a video was posted on YouTube - allegedly made on behalf of the hacker group Anonymous - warning Swedish authorities of repercussions.

Police spokesman Anders Ahlqvist says the website of Sweden's Courts Administration was swamped with false users, while links to a foul message was left at the National Board of Health and Welfare. Both sites are running again.

PRQ Head Mikael Viborg says his company previously hosted servers for file-sharing site the Pirate Bay and still houses some servers for the secret-spilling website WikiLeaks.
