trojan/Win32.deceiver.d - False Positive?

Tgarner3800 — Mon, 14 Sep 2026 19:33:42 GMT

I have noticed that PA NGFW sees this threat trojan/Win32.deceiver.d using Logon.exe from PCs in a specific zone (zone 1) going to our DCs that happen to be in a different zone (zone 2). I have had a couple of users say they have to type in their credentials a couple of times but we blamed DUO for that. In the Threat log I see only a few of the PCs in zone 1 application: ms-ds-smbv3, Type: virus or wildfire-virus, using port 445. When I look in the Wildfire Submissions: File name: logon.exe action: block.

We have Malwarebytes and Cortex - when I scan those machines - they come back clean.

Anyone else having this issue?

Maybe the logon.exe is dynamic and each time is different and Wildfire need to scan it. You can create rule that matches the app, the url and attach wildfire profile with not a "Hold" mode and also check the logs that it is not the Inline ML Wildfire that uses prebuild AI models for scanning without checking the Wildfire cloud.

See: "The system applies the fall back policy rule configured by the administrator, which determines whether to enable (permissive) or block (protective) the file."
