TL;DR: AWS access keys can be abused as valid IAM identities, and Wazuh shows how CloudTrail and GuardDuty telemetry can reconstruct validation, enumeration, persistence, and exfiltration stages to flag compromise before account takeover, according to Wazuh. The key issue is that long-lived credentials create a theft-to-abuse window that only tight monitoring and short-lived access can shrink.
NHIMG editorial — based on content published by Wazuh: detecting AWS access key compromise with native AWS telemetry
Questions worth separating out
Q: What breaks when AWS configuration files expose access keys?
A: When AWS configuration files expose access keys, the attacker inherits the workload’s identity and can often authenticate without triggering traditional login controls.
Q: Why do long-lived AWS credentials create more risk than task-scoped access?
A: Long-lived credentials expand the time available for misuse, copying, and lateral movement, especially when they exist in laptops, pipelines, or shared systems.
Q: How do security teams tell compromised API use from normal automation?
A: They correlate API sequences, source IP behaviour, and identity actions across CloudTrail and GuardDuty rather than treating each event separately.
Practitioner guidance
- Replace long-term keys with short-lived identity patterns Use IAM roles and ephemeral credentials wherever possible so the compromise window is reduced and the credential cannot be reused indefinitely.
- Correlate CloudTrail with behavioural findings Ingest CloudTrail and GuardDuty together, then write rules that connect validation, enumeration, persistence, and exfiltration into a single incident narrative.
- Harden the log path that proves compromise Enable CloudTrail log file integrity validation, restrict the log bucket with policy, and ensure your telemetry pipeline can read the exported findings without decryption failures or missing prefixes.

Wazuh's full blog post covers the operational detail this post intentionally leaves for the source:
- The exact CloudTrail and GuardDuty configuration steps used to generate the telemetry pipeline.
- The custom Wazuh rules that map validation, enumeration, persistence, and exfiltration into correlation logic.
- The full AWS and Wazuh emulation commands used to reproduce each stage of the compromise.
- The dashboard workflow used to investigate the combined alert stream in Threat Hunting.

Long-term access keys create identity persistence, not just secret exposure. Once an access key is public, the attacker can operate as the bound IAM identity until the credential is revoked or rotated. That means the real governance failure is not disclosure alone, but the existence of a durable credential that can be replayed in API workflows. Practitioners should treat every long-lived cloud key as a standing identity control problem, not a storage issue.
A few things that frame the scale:
- 88.5% of organisations acknowledge that their non-human IAM practices lag behind or are merely on par with their human identity and access management efforts, which helps explain why exposed machine credentials still become live attack paths.
- Another indicator from the same report shows that only 19.6% of security professionals express strong confidence in securely managing non-human workload identities, a maturity gap that directly affects cloud credential governance.
A question worth separating out:
Q: When should organisations prioritise key rotation over monitoring?
A: They should do both, but rotation comes first when the key is long-lived, broadly scoped, or exposed outside approved systems. Monitoring is still essential because it exposes misuse that may already be underway, but it does not remove the credential from circulation.
