" "description": "Credential dumping is the process of obtaining account login and password information from the operating system and software. Credentials can be used to perform Windows Credential Editor, Mimikatz, and gsecdump. These tools are in use by both professional security testers and adversaries.\\n\\nPlaintext passwords can be obtained using tools such as Mimikatz to extract passwords stored by the Local Security Authority (LSA). If smart cards are used to authenticate to a domain using a personal identification number (PIN), then that PIN is also cached as a result and may be dumped.Mimikatz access the LSA Subsystem Service (LSASS) process by opening the process, locating the LSA secrets key, and decrypting the sections in memory where credential details are stored. Credential dumpers may also use methods for reflective DLL Injection to reduce potential indicators of malicious activity.\\n\\nNTLM hash dumpers open the Security Accounts Manager (SAM) on the local file system (%SystemRoot%/system32/config/SAM) or create a dump of the Registry SAM key to access stored account password hashes. Some hash dumpers will open the local file system as a device and parse to the SAM table to avoid file access defenses. Others will make an in-memory copy of the SAM table before reading hashes. Detection of compromised Legitimate Credentials in-use by adversaries may help as well. \\n\\nOn Windows 8.1 and Windows Server 2012 R2, monitor Windows Logs for LSASS.exe creation to verify that LSASS started as a protected process.\\n\\nMonitor processes and command-line arguments for program execution that may be indicative of credential dumping. Remote access tools may contain built-in features or incorporate existing tools like Mimikatz. PowerShell scripts also exist that contain credential dumping functionality, such as PowerSploit's Invoke-Mimikatz module,[[Citation: Powersploit]] which may require additional logging features to be configured in the operating system to collect necessary information for analysis.\\n\\nPlatforms: Windows Server 2003, Windows Server 2008, Windows Server 2012, Windows XP, Windows 7, Windows 8, Windows Server 2003 R2, Windows Server 2008 R2, Windows Server 2012 R2, Windows Vista, Windows 8.1\\n\\nData Sources: API monitoring, Process command-line parameters, Process monitoring, PowerShell logs",\n",
