Exploring the QBOT Attack Pattern

Elastic Security Labs analyzed a QBOT (QAKBOT) sample, describing its execution chain (initial regsvr32-based DLL load and explorer injection), defense-evasion (watchdog process checks, Defender exclusions), persistence (user registry Run keys), privilege escalation (schtasks to SYSTEM), network infrastructure (138 IPs and 338 related samples), configuration extraction tooling, YARA detections, and downloadable ECS/STIX artifacts for detection and hunting.
