The group’s typical objectives—intelligence‑gathering, financial theft, and strategic positioning in the Middle East—align with the observed victim profile. The use of a custom C2 infrastructure and self‑signed certificates mirrors tactics seen in their 2023 campaign “SilkRoad”. MIDV-279

Motivation appears to be strategic espionage coupled with opportunistic financial gain (e.g., ransomware extortion after data exfiltration). The dual‑use of cloud services for exfiltration suggests an intent to blend with legitimate traffic and avoid detection.
