Linux Credential Cache

T1558.005 · MITRE ATT&CK

Obtain Linux Kerberos ticket material from the configured credential-cache backend. The procedures cover file-backed ccache inspection and use, Linux kernel KEYRING extraction with tickey, and SSSD KCM database decryption with SSSDKCMExtractor. Choose the path that matches the configured backend; these are alternatives, not sequential steps. tickey writes per-user ccache files, while SSSDKCMExtractor prints raw Kerberos JSON rather than a usable ccache. Extracted material is sensitive and its presence does not establish ticket validity or service access.
