These indicators of compromise (IOCs) were identified through LevelBlue Labs' proprietary collection and threat hunting processes, leveraging AI-driven heuristics to detect anomalous patterns, behavioral analysis of malicious activity, and cross-referenced intelligence from endpoint telemetry and external sources. The IOCs included in this pulse are associated with command and control (C2) infrastructure, facilitating malware communication, data exfiltration, and persistent threat actor operations. Use this data to enhance detection rules, block malicious infrastructure, or correlate with existing incident investigations. These indicators have been assigned a medium confidence level regarding their maliciousness. They are therefore subject to further review, and feedback is greatly appreciated.
