New OS X research warns of stealthier Mac attacks

  • In-memory code injection covers tracks

A computer security researcher has discovered a new way to inject hostile code directly into the memory of machines running Apple's OS X operating system, a technique that makes it significantly harder for investigators to detect Mac attacks using today's forensics practices.

The technique, which Italian researcher Vincenzo Iozzo plans to detail at the Black Hat security conference in Washington next month, makes it possible to carry out stealthy Mac attacks that until now have not been possible. The in-memory injection approach allows unauthorized software to be installed on a Mac without leaving traces of the attack code or other tell-tale signs that the machine has been compromised.

Similar stealth techniques have existed for more than two years for infecting Windows and Linux machines, but until now, researchers knew of no reliable way to cover their tracks when attacking Macs. It's likely only a matter of time until malware developers begin using the method in the wild, said researcher Charles Miller, who has reviewed Iozzo's work.
