Ever since a certain piece of malware hit the Modded Minecraft community last June, I've been intermittently (though more frequently in the past week) getting "MaliciousInboundSocket" when trying to use AuthMe, a Minecraft mod for refreshing your authentication session with Microsoft/Mojang's account servers. I get wanting to protect me from more malware of this type, and I guess there MIGHT be cases where localhost-localhost sockets are malicious, but this is obviously not one of those cases.
I've looked around a bit in my Malwarebytes control panel for a way to add an exclusion for my own IP address, as GENERALLY I don't have malware already on my system (I am USUALLY careful, e.g. checking code signing certs before installing things), and the specific attack I think this detection is meant to block didn't work that way anyway. However, thus far I have not found a way to do this, and have to fall back on temporarily disabling RTP when I got to use the affected callback.
Note: operative words are in bold. I am well aware these are, even for me, only "generally" true; if I were infallible and immune to social engineering, I probably wouldn't need your software, thanks for making it <3.
