AWS releases multi-part guide for CloudTrail incident investigations
Key points
- Guide focuses on analyzing AWS CloudTrail logs for incident response.
- Covers scenarios like cross-account access, crypto mining, and AI service abuse.
- Details a multi-stage attack on Amazon Bedrock services.
- Includes investigative techniques used by AWS Security Incident Response Team.
- Provides architecture diagrams, annotated logs, and investigation frameworks.
Overview of the Incident Response Guide
AWS has released a multi-part incident response guide to assist users in investigating suspicious activity within their AWS environments using AWS CloudTrail logs. The guide aims to move beyond basic CloudTrail queries to comprehensive security analysis, providing methodologies used by the AWS Security Incident Response Team (SIRT).
Key Scenarios Covered
Part 1 of the guide examines scenarios such as cross-account unauthorized access, cryptocurrency mining operations, and AI service abuse. It also covers cross-account Amazon Simple Storage Service (Amazon S3) data deletion with ransomware implications and cryptocurrency mining deployed through AWS CloudFormation using exposed AWS Management Console credentials.
Part 2 explores a more complex, multi-stage attack where a web application vulnerability leads to credential harvesting and unauthorized access to Amazon Bedrock services across multiple AWS Regions. This scenario, termed "SSRF to IMDSv1 credential harvesting with multi-Region Amazon Bedrock service misuse," demonstrates how threat actors chain together multiple techniques, including the use of Amazon Elastic Compute Cloud (Amazon EC2) Instance Metadata Service version 1 (IMDSv1).
Investigative Techniques and Resources
Each scenario in the guide includes architecture diagrams showing event progression, annotated CloudTrail logs highlighting significant fields, investigation frameworks with specific questions, and lessons learned with preventive measures. The guide is designed for security operations, cloud engineering, compliance, and leadership roles to improve their investigative mindset.
Strengthening Security Posture
The guide provides additional investigation techniques and hardening steps to strengthen an organization's security posture. By understanding how to interpret CloudTrail events, users can uncover the full scope of an incident and defend against complex cloud-based attacks.
