Security Playbook For Compromised Aws Account Credentials
Listen to this Post Your AWS IAM credentials are compromised and being used by a threat actor. Here’s a detailed playbook to contain, eradicate, and recover from the incident.
Step 1: Analysis – Validate Alerts & Credential Ownership – Check CloudTrail logs for unauthorized access: aws cloudtrail lookup-events --lookup-attributes AttributeKey=Username,AttributeValue=<COMPROMISED_USER> --start-time "2023-11-01T00:00:00Z" --end-time "2023-11-02T00:00:00Z" – Verify IAM user ownership: aws iam get-user --user-name <COMPROMISED_USER> Step 2: Scope the Incident & Inventory Affected Resources – Identify API calls made by the attacker: aws cloudtrail get-event-selectors --trail-name <TRAIL_NAME> – Check for unusual EC2 instances or S3 buckets accessed: aws ec2 describe-instances --filters Name=instance-state-name,Values=running aws s3api list-buckets Step 3: Determine Business Impact - Check if sensitive data was accessed: aws s3api list-objects --bucket <SUSPICIOUS_BUCKET> - Look for data exfiltration attempts: aws guardduty list-findings --detector-id <DETECTOR_ID> Step 4: Containment – Stop the Bleeding - Disable IAM Access Keys: aws iam update-access-key --access-key-id <KEY_ID> --status Inactive --user-name <COMPROMISED_USER> - Revoke Active Sessions: aws iam list-access-keys --user-name <COMPROMISED_USER> aws iam delete-access-key --access-key-id <KEY_ID> --user-name <COMPROMISED_USER> - Apply IP Restrictions (if possible): aws iam update-user --user-name <USER> --permissions-boundary '{"Version":"2012-10-17","Statement":[{"Effect":"Deny","NotAction":"","Resource":"","Condition":{"NotIpAddress":{"aws:SourceIp":["YOUR_IP"]}}}]}' Step 5: Eradication – Remove the Threat - Terminate malicious EC2 instances: aws ec2 terminate-instances --instance-ids i-1234567890abcdef0 - Delete suspicious S3 objects: aws s3 rm s3://malicious-bucket --recursive Step 6: Recovery – Restore Operations - Restore backups if data was deleted: aws s3 cp s3://backup-bucket/ s3://production-bucket/ --recursive - Re-enable legitimate access: aws iam update-access-key --access-key-id <NEW_KEY> --status Active --user-name <LEGITIMATE_USER> Step 7: Post-Incident – Learn & Improve - Automate Alerts: aws cloudwatch put-metric-alarm --alarm-name "UnauthorizedAPICalls" --metric-name "UnauthorizedAttempts" --namespace "AWS/CloudTrail" --statistic "Sum" --period 300 --threshold 1 --comparison-operator "GreaterThanOrEqualToThreshold" --evaluation-periods 1 - Enable GuardDuty for Future Detection: aws guardduty create-detector --enable You Should Know: - AWS CLI Commands for Incident Response: Check login history last -f /var/log/auth.log Monitor real-time network connections netstat -tulnp Check running processes ps aux | grep -i suspicious_process Linux log investigation grep "Failed password" /var/log/auth.log - Windows Incident Response Commands: Check active network connections netstat -ano List scheduled tasks schtasks /query /fo LIST /v Check for unusual services Get-WmiObject Win32_Service | Where-Object {$_.State -eq "Running"} | Select-Object Name, DisplayName, PathName What Undercode Say: AWS IAM breaches require immediate action.
Always rotate keys, enforce MFA, and monitor CloudTrail. Automate responses where possible to reduce human error. Prediction: As cloud adoption grows, IAM breaches will increase. Organizations will shift towards Zero Trust and AI-driven anomaly detection to mitigate risks. Expected Output: A structured incident response plan with executable AWS CLI and OS-level commands to detect, contain, and recover from IAM credential compromises.
