Graham Cluley of the Sophos security firm has written about a hidden change in Mac OS X 10.6.4 that is not mentioned in its release notes. Specifically, Apple included an update to the malware protection built into Mac OS X to protect against a backdoor Trojan the Cupertino-based Mac-maker identifies as "HellRTS". Sophos has been tracking the same trojan since April as OSX/Pinhead-B. It is distributed by malicious sources as the iPhoto application. The malware can provide a attacker with full access to an infected Mac, allowing for the taking of screenshots, sending spam, reading the clipboard, accessing files and so on. "Unfortunately, many Mac users seem oblivious to security threats which can run on their computers. And that isn't helped when Apple issues an anti-malware security update like this by stealth, rather than informing the public what it has done," Cluley wrote.
