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.
