Mac Trojan 'SabPub' Exploits Java and Microsoft Office

Over the weekend, security vendors discovered another information-stealing Trojan in the wild, targeting Tibetan sympathizers with vulnerabilities in Java and Microsoft Word.
Two versions of SabPub were discovered in the wild this past weekend, flying undedected for about two months now. Kaspersky's Costin Raiu wrote in a blog post that SabPub was probably written by the LuckyCat authors.
Version 1: Microsoft Office
One version of SabPub traps Mac (and potentially Windows) users with booby-trapped Microsoft Word documents which exploit the vulnerability 'MSWord.CVE-2009-00563.a.'
The spear-phishing emails containment a malicious Word attachment entitled '10^thMarch Statemnet' (with typo) to Tibet sympathizers. March 10, 2011 refers to the day the Dalai Lama delivered his annual speech observing the Tibetan Uprising of 1959.
The Word doc was created in August 2010 and updated in February with SabPub thrown in; "quite normal" for such attacks and seen in other APT's like Duqu, Raiu notes.
Version 2: JavaA March version of Sabpub also discovered last weekend exploits the same drive-by Java vulnerability seen in Flashback, one of the biggest botnet attacks seen in OS X. Once the backdoor Trojan is downloaded, a victim's system is connected to a command-and-control center via HTTP. From there the botnet can grab screenshots, upload/download files, and remotely execute commands, Sophos' Graham Cluley writes. SabPub drops the following two files on a user's system, so if you are concerned about infection Cluley recommends searching for these files:
/Users//Library/Preferences/com.apple.PubSabAgent.pfile
/Users//Library/LaunchAgents/com.apple.PubSabAGent.plist
