An APT group Molerats associated with Gaza has launched a new threat campaign using a malware NimbleMamba aimed at Middle Eastern governments, foreign policy think tanks, and even a state-owned airline.

The current attack was initiated by spear-phishing emails including links to malware files. Later attacks entice users to download malware files by redirecting them to Dropbox URLs and WordPress sites. Geofencing techniques were employed by the attackers to ensure that only inhabitants of the target nations were directed to the landing page. The final payload was a malicious RAR file containing the NimbleMamba malware and, on occasion, a trojan called ‘BrittleBush.’

NimbleMamba has the typical capabilities of an intelligence-gathering trojan, taking screenshots and acquiring process information from the host computer. Additionally, it can detect user interaction, such as looking for mouse movement. The malware also uses the Dropbox API for both C2 as well as exfiltration.
