Mac OS X OSX/Sabpab Trojan Detection

critical Nessus Plugin ID 58812
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Mac OS X host appears to have been compromised.

Description

Using the supplied credentials, Nessus has found evidence that the remote Mac OS X host has been compromised by a Trojan in the OSX/Sabpab (alternatively known as OSX/Sabpub) family of Trojans.

OSX/Sabpab is typically installed by means of a malicious Word document that exploits a stack-based buffer overflow in Word (CVE-2009-0563). Once installed, it opens a backdoor for a remote attacker to upload or download files, take screenshots, and run arbitrary commands.

Solution

Restore the system from a known set of good backups.
