From the source SKILL.md

The first hour decides how bad a ransomware or malware incident gets. Panic leads to the wrong moves — paying immediately, wiping evidence, or reconnecting an infected machine and spreading it. This gives a calm, correct sequence: isolate, preserve your options, and recover from the safest source — while being honest that a serious business incident needs professional responders.

What this skill does

Ransomware First Response is a community-contributed Claude Code skill in the malware-analysis sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/ransomware-first-response/ and loads when your prompt matches the skill's trigger.
