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.
2By any chance does that router still have factory password? Also some routers have some kind of log. You might want to take a look at it (if it was enabled). – Rhyuk – 2012-07-05T12:29:17.330
What kind of router do you have? – JoshP – 2012-07-05T12:35:31.893
The factory password had been changed. We've had a look for a router log but with no joy! Will check what type of router it is asap and get back to you... – Chris – 2012-07-05T12:51:13.373
2No. There is no way for the router to add its own port forwarding rules outside of the DEFAULT configuration. How exactly does your client have access to your network ( i.e. the network created by the router itself ). Verify all connections to the router are valid. If it has wireless support DISABLE it. – Ramhound – 2012-07-05T13:16:39.550
Thanks Ramhound - I'm happy for your comment to be the accepted answer but am unable to mark it as such. – Chris – 2012-07-05T13:35:00.540
