Thanks for opening an issue. Can you provide some additional info on the executable that's being flagged? For context, the Win32‑OpenSSH binaries published by Microsoft are Authenticode‑signed. Verifying the signature and sharing the exact asset and SHA256 would help us validate that the flagged file matches an official release artifact.

• name (i.e. ssh.exe for ARM64)
• source (i.e. directly from GtiHub release page)
• SHA256 hash

In addition to the kiosk hash scan, did any other scanners or workflow rules flag it?
