💡 WHAT THIS TEACHES: CSIRT INCIDENT RESPONSE & RANSOMWARE KILL SWITCHES
Effective Incident Response requires swift triage following the NIST SP 800-61 lifecycle: Containment halts lateral spread over SMB/RDP; Eradication strips malicious processes and LOLBins (like vssadmin.exe delete shadows); and Reverse Engineering uncovers operational flaws like the famous WannaCry kill-switch domain discovered by Marcus Hutchins, which suppressed worldwide execution once sinkholed.
