While specific details regarding the threat actor and initial attack vectors are not provided in this analysis, the report highlights the malware\u0026rsquo;s ability to dynamically change its command and control (C2) infrastructure and potentially leverage GitHub for code injection or storage. Understanding these techniques is crucial for defenders to develop robust detection and mitigation strategies against this evolving threat.
