A script written in python that identifies suspected areas of concern which should be looked closed at in a more detailed analysis. I've used this to find malicious browser extensions that are online and used today on Firefox and other browsers.

Check out the code here: https://github.com/ernos/browser-xpi-malware-scanner

There are a few guides/tutorials there as well.

Just because there is a positive doesn't mean it is malicious. It needs further analysis.
