The process tree shows standard Windows Update and system maintenance activity (wuauclt.exe, svchost.exe) alongside the detected binary.\n\n**IOC Analysis:** The file path C:\\Windows\\Temp\\...\\MpDlpCmd.exe is a characteristic location for temporary staging files during Microsoft Defender updates. The hash matches known legitimate Microsoft binaries, and the process spawned MpSigStub.exe which is standard for signature verification during Windows Update operations. No malicious behavior or unauthorized access was detected.\n\n---\n\n### \ud83e\udd16 deepseek-r1:8b Analysis (Secondary + RAG)\n**Verdict:** false_positive | **Confidence:** 0.95\nThe detection event is a false positive as \u0027MpDlpCmd.exe\u0027 is a legitimate Microsoft Defender Data Loss Prevention component commonly used in system update staging. The file location in C:\\Windows\\Temp\\ is typical for benign system operations, and no malicious activity was detected in the investigation.\n\n**IOC Analysis:** FILE_PATH: C:\\Windows\\Temp\\3A22930E-7933-4932-A06B-DA4B7DB2FB1F\\MpDlpCmd.exe is a known staging directory for Windows updates and Microsoft Defender components, making it benign.
