[T1003.008 ] OS Credential Dumping: /etc/passwd and /etc/shadow – Adversaries target the /etc/passwd and /etc/shadow files to obtain user account metadata and password hashes for offline cracking, often combining them with tools like unshadow and John the Ripper. Monitor and restrict access to these files, enable auditing, and watch command execution and file access logs to detect and respond to dumping attempts. #OSCredentialDumping #LinuxSecurity

[T1003.007 ] OS Credential Dumping: Proc Filesystem – Adversaries can extract credentials and cached secrets from Linux process memory exposed via the /proc pseudo-filesystem, leveraging files like /proc//maps and /proc//mem to locate cleartext passwords or hashes. Monitoring access to these proc files and scanning process memory usage patterns helps detect and mitigate this technique. #OSCredentialDumping #ProcFilesystem

[T1003.005 ] OS Credential Dumping: Cached Domain Credentials – Adversaries target cached domain credentials stored on endpoints to recover user passwords when domain controllers are unavailable, enabling lateral movement and persistence. Effective defenses include monitoring for credential-dumping tools, protecting and auditing local credential stores, and limiting cache usage. #CredentialDumping #CachedCredentials
