Swedish government email accounts have been hacked by the Anonymous hacktivist group, in response to last week’s seizure of The Pirate Bay servers by Swedish police.

The group also claims to have hacked into the government email accounts of Israel, India, Brazil, Argentina, and Mexico.

The hacktivist group left a message to those affected: "Warning: Merry Christmas & a Happy New Year to all!! Bye :*"

This is not the first time Swedish entities have been hacked following The Pirate Bay raid. On Friday, Swedish internet giant Telia was attacked, The Local reported.

Telia's online services were affected, as well as user connections. The chief researcher at Kaspersky Lab, David Jacoby, said the distributed denial-of-service (DDoS) attack was likely triggered by the police raid on The Pirate Bay in Stockholm.

"These attacks don't come from nowhere. The Pirate Bay raid has provoked feelings in these groups," Jacoby told TT news agency.

The company also came under cyber assaults on Tuesday and Wednesday.

On Tuesday, The Pirate Bay and several other torrent websites temporarily disappeared from the internet. The sites were downed in a raid by Swedish police, which seized the servers, computers, and equipment of previously elusive web pirates.

The Pirate Bay appeared back online later that day, changing its web domain to .cr (Costa Rica). However, torrent users have noted that the downloads were neither properly working, nor were free of charge, and came with unusual offers of a paid VIP service. Some said the .cr website could have been an old TPB mirror managed by a different group of people, while others referred to it as a scam.



Meanwhile, another well-known torrent site, isoHunt, unofficially "resurrected" the website under the name The Old Pirate Bay. Unlike many other sites that have sprung up in the aftermath of the raid, this one reportedly allows users to freely add new torrents to the database.

Earlier in September, The Pirate Bay announced new cloud technology which made its servers “raid proof,” adding that the 21 “virtual machines” (VMs) were scattered around the globe with cloud-hosting providers.

The cloud technology reportedly makes the site more portable and harder to take down.
