Service to check macOS app for malware?

[BoulderDash]

Hello,

I recently had someone on Upwork create a macOS app for me. Now, I have no reason to believe that they created a macOS app with malware included... I would like to trust... buit, I would especially like to verify.

I haven't run the app yet, as Gatekeeper prevented it from opening (though, I do know how to open it if needed), and I am interested in how I might get a service or software to take a look at the app package before I run it.

Is there a service or software that could open the app package up and verify that it's free of malware?

Thank you in advance!

You can check the app using Virus Total: https://www.virustotal.com/gui/home/upload
It'll check the file for malware and let you know if it contains anything suspicious.

Great... I'll give it a shot. Thank you!

It's not foolproof since VirusTotal is looking for known malware signatures. Which wouldn't be the same as someone adding a backdoor to a one-off application.

Definitely worth considering. To detect that, one would need to run a network filter like Little Snitch.

Thank you all for the above. I have added Intego's Mac Internet Security X9 to my iMac... which I believe functions as a network filter/barrier like Little Snitch, to augment VirusTotal's check.
