Find a playbook
Map alert titles to playbook files. Multiple alerts can share the same playbook. The agent reads this index first to find the right playbook for the current investigation.
How to use this index
Section titled “How to use this index”- Match the alert title (from
xdr incidents show <id> --expand alerts) against the Alert title column. - If a match is found, read the linked playbook file before continuing the investigation.
- If no match is found, fall back to the general methodology in
docs/investigation.md.
Matching is substring / fuzzy — e.g., an alert titled 'Rimecud' malware was prevented matches the Rimecud row.
