Users of Google Chrome and Mozilla Firefox who visited popular torrent site The Pirate Bay today were greeted with a malware warning — just like the one Kickass Torrents visitors saw last month and in October 2015. Navigating to http://thepiratebay.se results in a message cautioning you to go no further (“Deceptive site ahead” in Chrome and “Reported Web Forgery!” in Firefox).

Interestingly, if you navigate to https://thepiratebay.se in Firefox, you get a very bare homepage and only receive the warning if you search for a torrent. In Chrome, the error is there right off the bat.

This issue only affects those browsers because Google’s Safe Browsing is flagging the site. The service powers similar security features in Chrome and Firefox.

The warnings are a bit different depending on the browser you’re using, but the gist is the same. Chrome users are told that “Attackers on thepiratebay.se may trick you into doing something dangerous like installing software or revealing your personal information (for example, passwords, phone numbers, or credit cards).”

Firefox users are told, “This web page at thepiratebay.se has been reported as a web forgery and has been blocked based on your security preferences.”

Chrome users can get around this message by clicking Details and then “visit this unsafe site,” while Firefox users can click “Ignore this warning.” You should only do this if you trust The Pirate Bay, though we would recommend simply using another torrent site while the issue is addressed.

The diagnostics report offers little detail:

thepiratebay.se contains deceptive content. Don’t panic. Users sometimes post bad content on websites that are normally safe. Safe Browsing will update the safety status once the webmaster has cleaned up the bad content.

These types of warnings typically occur when an ad network is compromised and starts serving malicious ads. Because sites often use multiple advertising networks, some specific to certain regions, not all users are always affected. In short, at least one of The Pirate Bay’s pages is serving up malware, according to Google.

Chances are The Pirate Bay will find the problematic ad network and remove it. But as we’ve seen before, it will take days for the change to trickle down to Google’s Safe Browsing service.
