Step-by-step incident response playbooks (indicators, validation, containment, eradication and recovery, post-incident) for malware infection, account compromise, data breach, ransomware, DDoS, and insider threat. Use when responding to one of these incidents or writing its runbook.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Incident Response Playbooks > Playbook templates for common security incident types, providing step-by-step response procedures for each phase of incident handling. ## Knowledge Base ### Playbook Structure Every playbook follows the same four-phase structure from NIST SP 800-61: 1. **Detection & Validation** -- Confirm the incident is real, classify it 2. **Containment** -- Stop the spread, limit damage 3. **Eradication & Recovery** -- Remove the threat, restore operations 4. **Post-Incident** -- Document, learn, improve ### Playbook 1: Malware Infection **Indicators**: - Antivirus/EDR alert on malicious file or behavior - Unusual process execution (PowerShell encoding, living-off-the-land binaries) - Unexpected network connections to known bad IPs/domains - System performance degradation, unexpected file encryption - User reports of unusual system behavior **Detection & Validation**: 1. Verify the alert is not a false positive (check file hash against VirusTotal, check process lineage) 2. Identify the malware type: dropper, RAT, ransomware, cryptominer, wiper, worm 3. Determine the infection vector: email attachment, drive-by download, USB, lateral movement …

How to install
mdr add hermeticormus/libresecops-claude-code/ir-playbooks@sha256:849b950cadccbcc4The line at the top of this page pins the label git:20260930.71a2663, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
