From one phished admin to a cloud data breach

The prompt — read this to the room

At 02:15 a help-desk agent reset MFA for a cloud administrator after a convincing phone call. By 03:00 the attacker had registered a new device, created an access key in your production cloud account and disabled two logging trails. By 05:30, 3 TB had left a storage bucket holding customer documents. Your SOC sees an impossible-travel alert at 07:50. The identity, cloud and data teams each hold part of the picture, and each believes someone else is containing it.

Who to involve

Most important first.

  • Incident response lead
  • SOC analyst
  • Cloud engineer
  • IT operations
  • CISO / Head of security
  • Privacy officer / DPO
  • Developer / DevOps

What it tests

  • Establish a single incident command across identity, cloud and data teams within the first hour
  • Contain in the right order: sessions and credentials, then cloud keys and roles, then data paths
  • Reconstruct the attack timeline despite disabled logging, using alternative evidence sources
  • Hand the business a defensible statement of what data left and when

Outline of activities

  1. 1The alert and the first 30 minutes: who owns this
  2. 2Identity containment: the help-desk reset, devices, tokens
  3. 3Cloud containment: keys, roles, persistence and the disabled trails
  4. 4Data impact: what left the bucket and how you know
  5. 5Hardening before handover: closing the help-desk path
  6. 6Debrief: the seams between teams
