The investigation found no suspicious activity or child processes.\n\n**IOC Analysis:** OneDrive.App.exe is a legitimate Microsoft application used for cloud synchronization. The presence of the file in AppData\\Local\\Temp indicates it was likely launched from a OneDrive update or sync operation, which is common behavior. The process tree shows no suspicious children and no recent related events.\n\n---\n\n### \ud83e\udd16 deepseek-r1:8b Analysis (Secondary + RAG)\n**Verdict:** false_positive | **Confidence:** 0.8\nThe detection is likely a false positive due to the file being located in a temporary directory, which is common for legitimate processes, and no malicious activity was detected in the surrounding time window. Historical feedback for this rule type consistently indicates false positives.\n\n**IOC Analysis:** The FILE_PATH is in C:\\Users\\AppData\\Local\\Temp, which is atypical for system binaries and often used for temporary files, potentially leading to false positives. The hash is provided but not verified against known malware databases; however, the investigation found no suspicious activity, supporting a benign interpretation.",
