Heuristic detection based on suspicious behavior patterns, not a confirmed malware match
This is a generic/heuristic detection, `SuspGolang.M`, indicating suspicious activity possibly related to a Golang-based implant or post-exploitation framework. The identified strings suggest advanced capabilities such as credential harvesting, process migration, privilege escalation (e.g., GetSystem, Impersonate), in-memory code execution (ExecuteAssembly), and sophisticated command-and-control communication (e.g., DNSPoll, Protobuf serialization). While flagged with a high false positive risk, these capabilities, if genuine, represent a significant security threat.

Isolate the affected system immediately to prevent potential lateral movement or data exfiltration. Perform a comprehensive forensic analysis to determine the root cause, identify the scope of compromise, and confirm the legitimacy of the detection. If malicious activity is verified, revoke any potentially compromised credentials and consider a full system reimage.
