mimikatz
Windows credential extraction utility used in red team and DFIR exercises to test credential exposure and endpoint defensive controls.
Technical Architecture & Overview
Mimikatz is a Windows post-exploitation utility that extracts credentials and secrets from memory, registry, and protected stores. Security teams use it to test the resilience of credential protection controls and to validate the effectiveness of Credential Guard and LSA protection. The tool can dump passwords, hashes, Kerberos tickets, and DPAPI data for analysis.
Targeted Technical Use Cases
Use Mimikatz during authorized red team or DFIR exercises to find exposed credentials and validate endpoint credential protection settings.
Evaluation & Trade-offs
Core Strengths
- +Extracts many credential types, including passwords, hashes, tickets, and certificates.
- +Helps identify weak credential protection on Windows endpoints and domain controllers.
- +Can be scripted for automated assessment of credential exposure.
Trade-Offs & Limitations
- -Often detected by endpoint detection and response products.
- -Requires administrative access and does not work on systems with Credential Guard enabled for some secrets.
Defensive Security Application
Use Mimikatz to test endpoint credential protection, then enable Credential Guard, LSA protection, and reduce privileged account exposure.
