Summary
The Molerats threat group used an updated version of the SharpStage malware family known as LastConn to target governments in the Middle East. Email attachments with malicious links were used as the initial infection vector. The victim's IP address was checked and if it did not belong to the targeted countries the malware would direct the user to a news website instead of infecting the system. Dropbox was used for command and control and used to host the information stolen from entities.
The McAfee Enterprise ATR Team gathers and analyzes information from multiple open and closed sources before disseminating intelligence reports.
This campaign was researched by Proofpoint and shared publicly.
