This rule detects activities associated with suspicious credential dumping and lateral movement tool usage, specifically targeting 'DumpIt.exe' for memory dumping, 'dokan.exe' for potential driver installation, and the creation of known suspicious files like 'memfix.zip' or 'Server.raw'. These actions are commonly indicative of post-exploitation credential harvesting and preparation for exfiltration.
Detects Mimikatz binary or in-memory module used for credential harvesting following PaperCut RCE exploitation
This rule detects potentially malicious activities aimed at credential harvesting and system recovery inhibition. It monitors for the execution of vssadmin.exe with arguments to list shadow copies (often a precursor to deletion) or references to DPAPI master keys in command lines. Additionally, it identifies unauthorized processes attempting to access sensitive browser-based credential files (e.g., Login Data, Cookies, key4.db) from standard browser installation paths, specifically excluding legitimate browser and update processes.

This rule detects potential credential dumping attempts targeting the Local Security Authority Subsystem Service (LSASS) process. It identifies suspicious file execution based on a blocklist of known credential dumping utility hashes, unauthorized OpenProcess calls to lsass.exe with specific access rights, and the creation of process memory dump files (e.g., .dmp, .dump) correlated with an lsass.exe access event.

Detects various methods and tools used by adversaries to access, stage, or exfiltrate the Active Directory database (ntds.dit). This includes abuse of built-in Windows utilities such as ntdsutil, vssadmin, diskshadow, esentutl, and registry commands, as well as the use of known credential dumping tools like Impacket's SecretsDump and NinjaCopy.
Detects attempts to access or create copies of the Active Directory 'ntds.dit' database or the Windows Security Account Manager (SAM) registry hive using unauthorized processes. Attackers often target these files to extract credential hashes from Domain Controllers or local systems.
This rule detects potential extraction or caching of Kerberos Ticket-Granting Tickets (TGT) by correlating Kerberos authentication events (4768/4769) with unauthorized access to the Local Security Authority Subsystem Service (lsass.exe). This pattern is often indicative of credential dumping tools like Mimikatz targeting Kerberos tickets on systems potentially used for delegation attacks.
Detects Active Directory DCSync attempts by monitoring for Windows Security Event ID 4662 where the object properties contain GUIDs associated with directory replication services (DS-Replication-Get-Changes, DS-Replication-Get-Changes-All, and DS-Replication-Get-Changes-In-Filtered-Set). The rule excludes domain controller machine accounts and known legitimate service accounts used for synchronization or backup operations.

Detects unauthorized attempts to dump the process memory of the Local Security Authority Subsystem Service (LSASS), a common technique used by attackers to harvest credentials from memory. This includes the use of legitimate diagnostic tools like procdump and comsvcs.dll, as well as the identification of resulting dump files in directory paths associated with LSASS.

This includes the use of legitimate diagnostic tools like procdump and comsvcs.dll, as well as the identification of resulting dump files in directory paths associated with LSASS.
Detects instances where a process attempts to directly open or access the Active Directory domain database file (NTDS.dit). Direct access to this file is a strong indicator of credential dumping attempts, as the file contains sensitive password hashes and domain information.
