Auto-Purge Confirmed Phishing Across All Mailboxes

When an analyst confirms a phishing verdict, this searches every mailbox in the org for messages matching the malicious sender, subject, and URL.

What it does

Contains a confirmed phishing campaign before more users click. Given a confirmed indicator set, an agent fans out across the organization's Gmail mailboxes, finds every copy of the malicious message by sender, subject fingerprint, and embedded URL, purges them, and returns a containment summary.

When to use it

Use this immediately after triage confirms a message is malicious and you suspect it was blasted to many recipients. It replaces the slow, error-prone process of an admin running manual searches mailbox by mailbox.

How it works

  1. 1A webhook from your triage tool fires with the confirmed indicators (sender, subject hash, URL).
  2. 2A guard step verifies the payload is signed by your triage system and the verdict is genuinely "confirmed".
  3. 3The agent enumerates org mailboxes and runs a matching search across each one.
  4. 4Every matching message is moved to trash and permanently purged.
  5. 5A containment report listing affected users and deleted counts posts to Slack for the incident record.
