Detects Mimikatz binary or in-memory module used for credential harvesting following PaperCut RCE exploitation
This rule detects the execution of Mimikatz or the use of its specific command-line arguments, which are strongly indicative of credential dumping activities, often used for post-exploitation lateral movement or privilege escalation.
Detects the execution of Mimikatz, a tool commonly used for credential harvesting from Windows memory, by monitoring for processes named 'mimikatz.exe' or the presence of specific Mimikatz command-line arguments used for dumping LSASS memory or performing pass-the-hash attacks.
This rule monitors for a collection of adversarial behaviors on Windows systems, including persistence mechanisms via scheduled tasks and registry run keys, tampering with security services (VSS, Windows Defender), credential harvesting attempts (LSASS memory), log and history clearing, and external network communication to known IP geolocation services.
This rule detects the use of specific tools associated with credential dumping and memory forensics, including Dokan driver installations for file system mounting, the use of DumpIt for creating memory dumps, and the subsequent analysis of these dumps using MemProcFS to access sensitive process memory information such as LSASS minidumps.
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 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.

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 the use of Dumpert process dumper, which dumps the lsass.exe process memory
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.

Detects Mimikatz binary or in-memory module used for credential harvesting following PaperCut RCE exploitation
Detects Mimikatz binary or in-memory module used for credential harvesting following PaperCut RCE exploitation
This rule detects potential credential theft activity by monitoring for unauthorized access to sensitive browser-related credential files (e.g., Login Data, cookies.sqlite) or direct access to the LSASS process memory by non-standard browser processes. It further correlates these events with user sign-ins on previously unknown or unassociated devices within a short timeframe to identify potential account compromise.
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 the use of rundll32.exe to invoke the MiniDump export function of comsvcs.dll to create a memory dump of the LSASS process. This technique is often associated with post-exploitation credential access tools like lsassy or manual execution via remote management tools (e.g., WMI, MMC) by threat actors such as those in the Bumblebee/Akira ransomware intrusion chain.
Detects processes attempting to open a handle to the Local Security Authority Subsystem Service (LSASS) process with read-capable access rights (0x1010 or 0x1410). These access rights are commonly associated with credential dumping tools like Mimikatz, which read LSASS process memory to extract credentials. Legitimate system processes such as wininit.exe and services.exe are excluded to reduce noise.
