False Positive Communications

Early on 5\21\2022, Cisco Endpoint Protection trapped this event: 'detected a Cloud IOC: Executed Malware IOC'. It was classed as 'AMADEY' Malware. Because it was classified as a HIGH threat, and we have automated actions enabled, the affected computers were all ISOLATED from the network. That got attention.

By 4 PM the same day, the conviction was overturned and the computers with the detections attempted a RETROSPECTIVE RESTORE FROM QUARANTINE.

That is it. No explanation, no post anywhere that I can locate and reference in my RCA to close out the event.

Some person or process made a decision to reverse this conviction. The detail of the rationale and subsequent actions should be communicated. Possibly update the File Analysis details for the specific file(hash)?

Oh boy, do I feel silly. I just found this in one of my sorted email folders. It arrived on Saturday 5/21, in a very timely manner. It was my fault for not handling those notifications correctly. Anyone know where to send apologies to Cisco?
