Scenario: Cloud-Native Incident Response on AWS

A financial services organization running critical workloads on AWS detects unauthorized API calls through CloudTrail. The retainer's SLA-backed IR process activates immediately: Group-IB analysts reconstruct the attack timeline using CloudTrail logs, contain compromised IAM roles, capture forensic images of affected EC2 instances, and eradicate the attacker's persistence mechanisms - all while preserving chain of custody for regulatory reporting. Post-incident, the team delivers a root-cause analysis and updates the organization's IR playbooks to prevent recurrence.

Incident Response Methodology

Our IR service follows a structured lifecycle:

• Preparation: The IR team establishes operational foundations, bespoke playbooks, and forensic readiness before any breach occurs.
• Detection and Analysis: Complex telemetry and log data are analyzed to verify alerts, eliminate false positives, and reconstruct the attack vector.
• Containment and Forensics: The team halts threat proliferation without destroying volatile evidence - executing network isolation, endpoint quarantine, and IAM restrictions such as revoking compromised cloud credentials. Strict chain of custody is maintained through memory dumps and forensic images captured prior to remediation.
• Eradication: Reverse engineering of malware and root-cause analysis locate the initial point of ingress, ensuring complete removal of the attacker's presence.
• Recovery: Backup integrity is validated to confirm absence of sleeper malware before staged restoration. Heightened monitoring detects potential reinfections during re-entry.
• Post-Incident Activity: Post-mortem reviews feed empirical data back into preparation, refining playbooks and updating security controls. Tabletop exercises validate readiness during peacetime.

AWS Integration

The retainer integrates with AWS for organizations running cloud workloads. Group-IB leverages AWS CloudTrail for forensic analysis of API activity, Amazon GuardDuty findings for detection context, and VPC Flow Logs for network-level reconstruction. Prerequisites: clients should have CloudTrail enabled across all regions and retain logs for a minimum of 90 days to support effective forensic analysis.
