Macs under attack from trojan double whammy

Posted by   Virus Bulletin on   Jun 30, 2008

Two new threats in a week spark worries of approaching Mac malware era.

Users of Apple Mac systems, who have so far only suffered from minimal attention from malware creators, may need to take more care in future according to some security analysts, after the exposure of a significant vulnerability in the operating system and the release of two effective trojans within a week have left some pondering the possible advent of major malware problems for the Mac world.

The most significant threat comes from a trojan toolkit posted online, with its Applescript source designed to be hidden in any genuine application. Once running it attempts to exploit several known vulnerabilities, including a recently disclosed privilege escalation flaw, to install keyloggers and remote access tools. While the developers of the trojan have apparently claimed to have intended it merely as a proof-of-concept, Mac security specialist SecureMac reports sightings of several variants in the wild, and with the source being available and designed to be modular for easy adaptation, it seems likely that more will follow.

A second and less potent risk was also spotted targeting Mac users last week, which relied on social engineering rather than system vulnerabilities to obtain admin credentials on target systems. Having persuaded victims to provide passwords the malicious program then passes them on to a central point along with other system data.

An initial post on the Applescript trojan toolkit is at SecureMac here, with more analysis and investigation on the SecurityFix blog here and in the Register here.
