Detects the creation of named pipes commonly used by credential dumping tools such as Mimikatz (wceservicepipe) and other tools that might use 'cachedump' or 'lsadump' in their pipe names to extract credentials.
Detects access to the LSASS process by a Python-based tool, indicated by specific call trace patterns involving Python DLLs and KERNELBASE.dll/ntdll.dll, combined with a broad granted access right (0x1FFFFF). This activity is characteristic of credential dumping tools like LaZagne or Pypykatz.
This rule detects attempts to dump the NTDS.dit database to suspicious locations. It specifically looks for ESENT event ID 325 (New Database Created) where the data contains 'ntds.dit' and the path includes common suspicious directories such as Appdata, Desktop, Downloads, Perflogs, Temp, or Users\Public.
Detects WerFault creating a dump file with a name that indicates the dump file could be an LSASS process memory dump, which contains user credentials. This technique is often used by adversaries to extract credentials for lateral movement or privilege escalation.
Detects the execution of Quarks PwDump, a tool used for dumping credentials, by monitoring process creation events for its executable name and specific command-line arguments. The rule looks for 'QuarksPwDump.exe' and various flags associated with dumping local hashes, domain cached hashes, BitLocker keys, and domain hashes, including those from NTDS files.
Detects potential credential dumping via the Windows Error Reporting (WER) LSASS Shtinkering technique. This technique abuses WerFault.exe to dump the LSASS process memory. The rule specifically looks for WerFault.exe being executed with command-line arguments indicating a dump of a target process (-p) that is not the source process (-ip), and where the target process is likely LSASS.
Detects attempts to access the LSASS process memory by tools or processes that have the keyword "dump" in their image name. This behavior is indicative of credential dumping activities, where adversaries try to extract sensitive information like passwords and hashes from the LSASS process.
This rule detects the use of the legitimate Microsoft SQL Server utility `sqldumper.exe` to dump process memory. Specifically, it looks for `sqldumper.exe` being executed with command-line arguments that indicate an attempt to dump a process, such as '0x0110' or '0x01100:40'. This technique can be abused by attackers to dump sensitive processes like LSASS (Local Security Authority Subsystem Service) to extract credentials.
Detects the execution of PowerShell scripts containing patterns commonly associated with Mimikatz, a tool used for dumping credentials. The rule looks for specific strings related to Mimikatz functionalities like 'DumpCreds', 'DumpCerts', 'sekurlsa::logonpasswords', and 'crypto::certificates' in conjunction with 'CERT_SYSTEM_STORE_LOCAL_MACHINE'.
Detects the creation of memory dump files (.dmp, .hdmp) by common scripting or shell applications such as cmd.exe, powershell.exe, cscript.exe, mshta.exe, pwsh.exe, or wscript.exe. Memory dumps can contain sensitive information like credentials, and their creation by these processes can be indicative of malicious activity, especially if not tied to a legitimate crash.
This rule detects the creation of a dump file by the password dumper tool QuarksPwDump. Specifically, it looks for files created in the 'AppData\Local\Temp\' directory with names starting with 'SAM-' and ending with '.dmp'. This pattern indicates that QuarksPwDump is attempting to dump the Security Account Manager (SAM) database, which contains local user credentials.
Detects changes to the Windows Registry that configure a monitor program to dump the memory of the lsass.exe process using the SilentProcessExit technique. This method leverages Image File Execution Options (IFEO) to trigger a memory dump of LSASS when it exits, which can be used to extract credentials.
This rule detects the creation of a file named 'lsass.exe.dmp' within the 'C:\Windows\System32\config\systemprofile\AppData\Local\CrashDumps\' directory. This specific file pattern and location are indicative of an attempt to dump the LSASS process memory, which often contains sensitive credential material. Adversaries frequently use this technique to extract credentials for lateral movement or persistence. The rule specifically references the 'LSASS Shtinkering' technique, which abuses Windows Error Reporting to achieve LSASS memory dumping.
Detects attempts to dump LSASS process memory using WerFault.exe. This technique is often used by tools like Mimikatz, NanoDump, Invoke-Mimikatz, Procdump, or Taskmgr to extract credentials from the Local Security Authority Subsystem Service (LSASS) process. The rule specifically looks for WerFault.exe accessing lsass.exe with a GrantedAccess of '0x1FFFFF', which indicates full access.
Detects a possible process memory dump of lsass.exe using a renamed or masqueraded executable named 'TrolleyExpress.exe'. This technique leverages the whitelisted nature of the legitimate Citrix TrolleyExpress.exe to evade detection while attempting to dump LSASS memory, often indicated by command-line arguments targeting process IDs in the 700-999 range or the '-ma' flag for memory dumping.
Detects the execution of the hacktool SafetyKatz, which is used for credential dumping, by identifying its executable name, original file name, or description in process creation events.
This rule detects the creation of a new process where both the parent process and the new process are 'lsass.exe'. This behavior is highly suspicious and indicative of credential dumping techniques, specifically attempts to clone the LSASS process to extract credentials without directly interacting with the original LSASS process, which might be protected by security solutions.
