Detects the execution of known credential extraction tools such as Mimikatz, LaZagne, Hashcat, or John the Ripper, indicated by specific keywords in the command line arguments. This rule monitors for process creation events (EventID 4688) where these tools are used in conjunction with keywords related to passwords, hashes, or credentials.

Detects download of known offensive security and post-exploitation tools
Detects the execution of LaZagne, a utility used to retrieve multiple types of passwords stored on a local computer. LaZagne has been leveraged by threat actors to dump credentials.
Detects LSASS process access for potential credential dumping by a Python-like tool such as LaZagne or Pypykatz.
Detects LSASS process access by LaZagne for credential dumping.

This query was originally published in the threat analytics report, Ryuk ransomware. There is also a related blog.
Ryuk is human-operated ransomware. Much like DoppelPaymer ransomware, Ryuk is spread manually, often on networks that are already infected with Trickbot.
During a typical Ryuk campaign, an operator will use LaZagne, a credential theft tool, to access stored passwords for service accounts. The accounts are then used to jump from desktop clients to servers or domain controllers, allowing for better reconnaissance, faster movement, and a more severe impact on the target.
The following query detects credential theft by LaZagne.

Use this query to locate processes executing credential theft activity, often LaZagne in ransomware compromises.
This rule detects highly relevant antivirus events in the Windows Application log by looking for specific keywords associated with known virus signatures, malware, and offensive security tools. It aims to identify instances where an antivirus product has detected or quarantined malicious software or activity.
Detects attempts to extract credentials from files using the 'grep' command to search for the keyword 'password' or by executing the 'laZagne' credential dumping tool. This rule is specifically tailored for macOS environments.
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.
