T1552: Unsecured Credentials

Last reviewed:

T1552 is the umbrella technique for credentials left where attackers can read them: plaintext secrets in environment variables, keys committed to repositories, unencrypted secret stores. More cloud breaches start here than with any exploit. DCV anchors coverage in AWS Security Hub's FSBP controls: the Secrets Manager rotation series, CodeBuild checks for plaintext credentials in build environments and the EKS secrets-encryption control, with GCP Security Command Center contributing equivalent findings. Rotation cadence is the metric that separates written policy from actual practice.

01 What is T1552?

Adversaries may search compromised systems to find and obtain insecurely stored credentials. These credentials can be stored and/or misplaced in many locations on a system, including plaintext files (e.g. Shell History), operating system or application-specific repositories (e.g. Credentials in Registry), or other specialized files/artifacts (e.g. Private Keys).

Platforms: Windows, SaaS, IaaS, Linux, macOS, Containers, Network Devices, Office Suite, Identity Provider.

02 Coverage in DCV

DCV maps 13 detections across 3 cloud providers to T1552. Coverage by source:

Source Cloud Findings mapped Avg confidence
AWS Security Hub AWS 8 0.83
Azure Regulatory Compliance Azure 2 0.93
GCP Security Command Center GCP 2 0.88
GCP Chronicle GCP 1 0.90

03 Detect with CloudSigma

CloudSigma has coverage metadata for 13 T1552 rules across 6 platforms. The linked platform page remains the canonical rule surface; this page will embed an example after a rule clears the public embed bar.

CloudSigma has coverage metadata for T1552, but no public example rule clears the embed bar for this page yet. Generate a fresh starting-point rule in CloudSigma from the relevant advisory or threat-research input, then validate it against your local telemetry before enabling it in production.
