HeavyLift : A previously unknown Electron-based malware loader family distributed via malicious installers targeting the Windows operating system.
12 distinct techniques documented for this family, organized by ATT&CK tactic.
The other infection vector, gaining popularity in this operation, and now a staple tactic of the Cosmic Leopard’s operations consists of contacting targets over social media channels, establishing trust with them and eventually sending them a malicious link to download either the Windows- or Android-based GravityRAT or the Windows-based loader, HeavyLift.
On macOS, the payload is a ZIP file that is extracted, and the resulting binary persists using crontab via the command: crontab -l 2>/dev/null; echo ' */2 * * * * “_filepath_” _arguments_ ‘ | crontab -
For Windows, the payload received is an EXE file that persists on the system via a scheduled task. The malware will create an XML file for the scheduled tasks with the payload path, arguments and working directory and then use the XML to set up the schedtask: SCHTASKS /Create /XML "_xmlpath_" /TN "_taskname_" /F

The latest variants of GravityRAT are distributed through malicious websites, some registered and set up as late as early January 2024, pretending to distribute legitimate Android applications.
In some cases, the malware will also perform anti-analysis checks to see if it’s running in a virtual environment. It checks for the presence of specific keywords before closing if there is a match: Innotek GmbH VirtualBox VMware Microsoft Corporation HITACHI
The malware will then obtain preliminary system information such as: Processor ID MAC address Installed anti-virus product name Username Domain name
