Security experts have discovered two new attacks targeting Mac users, a new version of a worm and a Trojan hidden inside a porn site.

Sophos on Wednesday discovered a new version of the Mac OS X Tored worm, according to a Sophos blog post.

On Tuesday, Paretologic warned about a porn site that was downloading malware that targets both the PC and the Mac. Mac users get redirected to the pagemac.php page, which downloads a QuickTime.dmg file, the blog post says.

Sophos explained in blog post on Thursday that visitors to the malicious porn site are told they have to download an ActiveX component to view the videos. Instead, a Trojan, dubbed OSX/Jahlavc, gets downloaded.
