At work, just noticed that in one of our private repo s contributors page, some strange user was being displayed. Knowing that it could be simply due to some e-mail appearing in the author s commit or within the very own commit message, I just went around looking for anything suspicious in the timeframe from where the commit mentioning this strange user apparently happened.After some digging, I tracked down to some commit with the following snippet at the end Co-authored-by: Copilot copilot@github.com . Well, it could be it, but would be very strange if that was the case. So, in my personal account, I created a private, separate repo and tested. A simple commit, arbitrary title, but with a commit message having the exact same string: Co-authored-by: Copilot copilot@github.com .Again, for this test, I didn t use Copilot to generate the commit or the actual change , but rather just added this string to the message. The commit resolves that e-mail to the exact same strange user I saw in the collaborators list of the company s repo. It s resolving to this guy: github.com/00sadik-lab.Can anyone confirm the same behaviour?
