Bit of an interesting situation here.
Several of us work in a small office, of which only a few people have access to the router. While setting up a Minecraft server the other day, my friend noticed that a new port forwarding rule had been added which opened up RDP to my machine specifically.
One of the people we share an office with is a fairly tech-savvy client of ours, who is currently disputing an invoice we have sent and has a decent motive to attempt a remote connection to my PC and help himself to the source code without having to pay for it.
Before we put 2 and 2 together and possibly come up with 5, is there any chance whatsoever that a port forwarding rule in a router could somehow be automatically generated by the router's firmware itself, possibly in some response to incoming/outgoing activity? I'm 99% sure that it couldn't, but the ramifications of this will most likely involve somebody getting ejected from the office, so we need to discount all possible explanations!
Thanks very much.
