This allows for the exfiltration of saved usernames and passwords. The tool vaultcmd.exe can be used to interact with the Credential Manager and list the stored credentials. This activity is often performed in preparation for lateral movement within a compromised network. This detection focuses on identifying instances where vaultcmd.exe is executed with the \u003ccode\u003e/list*\u003c/code\u003e argument, indicating an attempt to enumerate stored credentials. The detection rule is designed to identify abuse of vaultcmd for credential access, enabling defenders to detect unauthorized credential access activities.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAn attacker gains initial access to a Windows system through various means (e.g., phishing, exploitation of a vulnerability).\u003c/li\u003e\n\u003cli\u003eThe attacker executes \u003ccode\u003evaultcmd.exe\u003c/code\u003e with the \u003ccode\u003e/list\u003c/code\u003e argument to enumerate the credentials stored in the Windows Credential Manager.\u003c/li\u003e\n\u003cli\u003eThe \u003ccode\u003evaultcmd.exe\u003c/code\u003e process accesses the Credential Manager to retrieve the list of saved credentials.\u003c/li\u003e\n\u003cli\u003eThe output of \u003ccode\u003evaultcmd.exe\u003c/code\u003e (the list of credentials) is captured or redirected to a file for later exfiltration.\u003c/li\u003e\n\u003cli\u003eThe attacker parses the output to identify valuable credentials, such as domain administrator accounts or service accounts.\u003c/li\u003e\n\u003cli\u003eThe attacker uses the acquired credentials to authenticate to other systems on the network (lateral movement).\u003c/li\u003e\n\u003cli\u003eThe attacker elevates privileges on the target systems.\u003c/li\u003e\n\u003cli\u003eThe final objective is achieved, such as data theft or ransomware deployment.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful execution of this attack chain can lead to unauthorized access to sensitive resources, lateral movement within the network, and ultimately, data theft, system compromise, or ransomware deployment.
