SabPub Mac OS X Backdoor: Java Exploits, Targeted Attacks and Possible APT link

Last week, Apple released two urgent updates to Mac OS X to:

1. Remove the Flashback malware about which we have already written

2. Automatically deactivate the Java browser plugin and Java Web Start, effectively disabling java applets in browsers

Particularly, the second step shows the severity of the CVE-2012-0507 vulnerability exploited by Flashback to infect almost 700,000 users via drive-by malware downloads.

Actually, it was the right decision because we can confirm yet another Mac malware in the wild – Backdoor.OSX.SabPub.a being spread through Java exploits.

This new threat is a custom OS X backdoor, which appears to have been designed for use in targeted attacks. After it is activated on an infected system, it connects to a remote website in typical C&C fashion to fetch instructions. The backdoor contains functionality to make screenshots of the user’s current session and execute commands on the infected machine.
