Summary
The National Cybersecurity Agency of France (ANSSI) investigated incidents involving Qakbot infections that were reported to ANSSI from 2020 to 2021. The correlations made between the incidents involving these French companies helped in identifying commonalities in TTPs as well as naming conventions and the malware used. This led to the identification of a new threat group, which is now being tracked as Lockean. Along with the initial Qakbot infections, the threat actor was seen delivering Cobalt Strike, which was using spoofed Akamai and Azure domains for C2 communication, Rclone for data exfiltration, and the final payloads being one of a few RaaS payloads.
Our Threat Research team gathers and analyzes information from multiple open and closed sources before disseminating intelligence reports. This campaign was researched by CERT-FR and shared publicly.
