Credentials from Password Stores

142 rules · 138 families across 11 sources.

From MITRE ATT&CK 19.2

Adversaries may search for common password storage locations to obtain user credentials. Passwords are stored in several places on a system, depending on the operating system or application holding the credentials. There are also specific applications and services that store passwords to make them easier for users to manage and maintain, such as password managers and cloud secrets vaults. Once credentials are obtained, they can be used to perform lateral movement and access restricted information.

How MITRE says to detect it DET0430

Detect Credentials Access from Password Stores

Windows Analytic 1198

Monitors suspicious access to password stores such as LSASS, DPAPI, Windows Credential Manager, or browser credential databases. Detects anomalous process-to-process access (e.g., Mimikatz accessing LSASS) and correlation of credential store file reads with execution of non-standard processes.

  • WinEventLog:Sysmon EventCode=10
  • WinEventLog:Security EventCode=4663, 4670, 4656
  • WinEventLog:Sysmon EventCode=1

Linux Analytic 1199

Detects access to known password store files (e.g., /etc/shadow, GNOME Keyring, KWallet, browser credential databases). Monitors anomalous process read attempts and suspicious API calls that attempt to extract stored credentials.

  • auditd:SYSCALL open/read
  • auditd:EXECVE execve

macOS Analytic 1200

Monitors Keychain database access and suspicious invocations of security and osascript utilities. Correlates process execution with attempts to dump or unlock Keychain data.

  • macos:unifiedlog access to keychain database
  • macos:unifiedlog execution of security or osascript

IaaS Analytic 1201

Detects attempts to access or enumerate cloud password/secrets storage services such as AWS Secrets Manager, Azure Key Vault, or GCP Secret Manager. Monitors API calls for abnormal enumeration or bulk retrieval of secrets.

  • AWS:CloudTrail GetSecretValue
  • AWS:CloudTrail Decrypt
