Last week, my cable modem went dead, and the ISP guys came over to my house and replaced the modem, but they came while I was away.
I was told that they spent a very long time configuring my cisco linksys wireless router and TPLink wireless repeater. For some reason paranoia kicked in and alarm bells started ringing in my head, I got to thinking that maybe they were installing some sort of spyware to monitor my home network traffic, maybe some kind of MITM. Since they came I haven't been able to open the web admin panel, it just shows a 502 bad gateway error and I haven't had time to fix it.
I am an IT guy but not exactly a security expert. How do I find out if there is such a thing?
- this is in a far east country where consumer protection laws are practically nonexistent.
- just to clarify it doesn't necessarily have to involve the ISP, I also consider the possibility that it's just a couple of rogue technicians installing surveillance for their own purposes.
