米米卡茨
儘管Mimikatz可以通過破壞Windows操作系統中確定的功能來使攻擊者訪問計算機，但它沒有被歸類為高風險工具。當計算機受到Mimikatz攻擊時，其控制器可以將DLL注入隨機進程，導出安全證書，從Windows恢復純文本密碼，禁用某些登錄名和安全服務，擦除某些特權並逃避一些組策略設置。
如果您懷疑Mimikatz可能感染了您的計算機，則有一種簡單的檢查方法：使用專用的掃描儀，因為它可以檢測並刪除Mimikatz。但是，如果您沒有受到感染，並希望採取措施避免感染，則可以實施一些策略，例如檢查來自未知發件人的電子郵件的來源和可靠性，在共享文件時要謹慎，不要共享給其他人。有關即時通訊工具的大量信息，這些信息可以防止無數問題，包括被更嚴重的威脅所感染。

Similar Families
Similar Families
This section lists other families that share similarities with this family, based on EnigmaSoft’s analysis. Many malware families are created from the same malware toolkits and use the same packing and encryption techniques but uniquely extend functionality. Similar families may also share source code, attributes, icons, subcomponents, compromised and/or invalid digital signatures, and network characteristics. Researchers leverage these similarities to rapidly and effectively triage file samples and extend malware detection rules.- MSIL.SharpKatz.B
