Second Mac Os X Worm Spreads Via Bluetooth Vulnerability, Reports Sophos

Experts at SophosLabs, Sophos’s global network of virus, spyware and spam analysis centres, have issued protection against a second worm for Mac OS X. The new worm, called Inqtana-A, spreads between Apple Macintosh computers via a Bluetooth vulnerability and has appeared within days of the discovery of the first ever real virus for Mac OS X.

The Inqtana worm exploits a vulnerability (known as CAN-2005-1333) to spread itself to other vulnerable Mac OS X computers, but Apple released a patch against the vulnerability in mid 2005, meaning the worm is highly unlikely to spread successfully. However, Sophos is urging users of Mac OS X to keep their software updated against the latest security vulnerabilities in Apple’s code.

“It’s disturbing to see a second worm for Mac OS X so soon after the first, but it should be remembered that this is only two compared to well over 100,000 viruses for Microsoft operating systems,” said Graham Cluley, senior technology consultant for Sophos. “The good news is that Inqtana is not going to spread successfully in the wild, but this announcement will still be a shock to those in the Mac community who thought hackers were not interested in their operating system.”

A report issued by Sophos last week revealed that 79% of people believed that Apple Macintoshes would be targeted more in future, following the discovery of the first Mac OS X worm.

“The question on everyone’s lips is – when will we see the next one, and will it have a more malicious payload,” continued Cluley. “Apple Mac users need to be just as careful about protecting their computers with anti-virus software, firewalls and security patches as their friends and colleagues using Windows.”
