Auto-detected from the MITRE ATT&CK catalog on 2026-09-28 (S0638) - this entry has not been reviewed or curated yet. See the MITRE ATT&CK link below for what's currently known; a proper summary and authoritative eradication references are pending.

Detection & eradication references

Curated links to authoritative sources — MITRE ATT&CK, CISA advisories, law-enforcement takedown announcements, and vendor threat-intel writeups — for removal, remediation, and further technical detail. Sigma Watch does not publish its own removal steps here, since malware behavior and tooling change too fast for a static write-up to stay reliably accurate.
