Thanks Al.

Sorry for all the confusion. My testing earlier today was in error.

OpenSSH version 7.2_p2 is in fact included with macOS Sierra 10.12 and includes the ssh-agent process which tests as infected with Win.Trojan.Agent-1760811 and is therefore a False Positive.

I have submitted it to the web site at this time and has an MD5 of 3cbe857b1bc267fb8fa5da3856008ddd.

Virus Total shows only ClamAV detection:

This is the third FP submitted in the last two days where ClamAV is the only scanner on VT showing infection of a legitimate commercial software file, so I have to wonder if there is some systemic issue with the signature automation process now.

Heard back from one user that they have OpenSSH_7.2p2, LibreSSL 2.4.1 installed, which is not part of any standard OS X/macOS installation. I know where I can get 7.2p1 (MacPorts) but no idea where his 7.2p2 came from.

Sorry, I misidentified ssh-agent as part of OpenSSL. It’s actually a component of SSH that’s included with OS X/macOS.

I’m still trying to track down a sample of the version involved here.

I do not have a sample of ssh-agent to upload yet, so with nothing to upload, I cannot file.

The MD-5 of the file is the signature.
