Concept: Windows Credential Manager securely stores authentication credentials for websites, applications, and network resources using Data Protection API (DPAPI) encryption. Adversaries extract these encrypted credentials by obtaining the DPAPI master key through local or remote access, leveraging tools like Mimikatz, DonPAPI, or PowerShell APIs to decrypt stored .vcrd files, ultimately exposing plaintext passwords and authentication tokens for lateral movement and unauthorized access.
Attack Surface: DPAPI-encrypted credential files (.vcrd) located in %SystemDrive%\Users\[Username]\AppData\Local\Microsoft\Vault and AppData\Roaming\Microsoft\Vault, encryption keys stored in Policy.vpol, master keys in AppData\Roaming\Microsoft\Protect\[SID].
Business Impact: Unauthorized credential disclosure and lateral movement. Compromised credentials enable attackers to impersonate users, access shared resources, escalate privileges, and maintain persistence across the network. In enterprise environments, exposed domain credentials stored in Credential Manager can result in widespread compromise of multiple systems and services.
Technical Context: Extraction typically requires either user-level access (with user’s plaintext password or active session) or Local Administrator privileges. Success rate varies: some credentials can be extracted within seconds if user is logged on and Mimikatz is available; domain credentials require additional DPAPI backup key access (Domain Admin privileges). Detection likelihood is moderate-to-high due to distinctive event patterns in Event ID 4693, 16385, and process execution signatures.
Execution Risk: Medium - Requires elevated privileges or active user session; Mimikatz execution may trigger EDR; DPAPI operations generate detectable events if auditing is enabled.
Stealth: Low - Direct file access and DPAPI decryption operations generate 4693/16385 events; vaultcmd.exe execution is suspicious and monitored by most SIEM platforms.
Reversibility: No - Once credentials are extracted and decrypted, they cannot be “unexposed.” Mitigation requires password resets and Credential Manager purging.
