Description
AWS S3 discovery operation.
Attacker's Goals
- Identify accessible buckets, enumerate their contents, and assess permissions or public exposure.
- Locate sensitive data, evaluate exfiltration paths, and plan privilege escalation or misconfiguration abuse.
Investigative actions
- Verify if the identity normally interacts with S3 in this environment.
- Check whether the activity was part of a legitimate application or automated process, or if it appears interactive or out-of-pattern.
- Look for signs of broad enumeration, such as listing multiple buckets or traversing objects across different buckets.
- Investigate whether the accessed bucket or objects contain sensitive data or are configured for public or cross-account access.
- Correlate with other actions to determine if data was accessed, exfiltrated, or altered.
