Question
A threat actor emails your CEO claiming to have exfiltrated 1.2TB of customer data and will publish it in 72 hours unless paid; they attach a sample of real customer records as proof. No systems are encrypted yet and operations look normal. Investigation finds an internet-exposed RDP jump host with a weak password that has successful logins from a foreign IP over the past three weeks, and your cloud storage logs show a large outbound transfer from a backup bucket 9 days ago. How do you triage, contain, and remediate a double-extortion (exfil-only, pre-encryption) scenario?
Stop the bleeding first (mitigate), then form hypotheses from real signals. Separate root cause from symptom, communicate status as you go, and close with what prevents a repeat.
