Two new pieces of malware for the Apple Mac OS X operating system have been detected in the wild, according to security firm Sophos.

Two new pieces of malware for the Apple Mac OS X operating system have been detected in the wild, according to security firm Sophos.

The first is the OSX/Tored-Fam worm, which spreads via e-mail attachments. The worm, which collects e-mail addresses and attempts to forward itself, is being used to build a Mac botnet of hijacked computers, security researchers suspect.

The second is a Trojan horse, called OSX/Jahlav-C is found on what looks like a pornography site. Users are lured into activating the Trojan by a message that says they need to download an ActiveX component to view the site's content.

The Trojan uses a Perl script to communicate with a remote website and download code supplied by the attacker to take control of the computer.

Anyone switching to Apple computers because they think they are immune from attacks through websites is making a mistake, said Graham Cluley, senior technology consultant at Sophos.

"We are seeing more attacks against Mac users all the time, with hackers planting bear-traps that work out if you are visiting their page on a Windows or Mac computer, and deliver the appropriate malicious payload accordingly," he said in a blog posting.
