Did Apple Update Mac's Malware Protection-But Not Tell Anyone?

Sophos senior technology consultant Graham Cluley, in a Friday blog post, asserts that Apple quietly patched the Mac's malware protection to thwart a backdoor Trojan horse that could allow hackers to control an iMac or MacBook remotely.

"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."
