I had an engineer about my router to sort out my issue and he noticed that I gamed a lot during the past few days. (I rarely do but got a cool game so I did a bit lately). I just wonder how? Well I did download a game last night and last month. I am wondering, did he see just my download history (which is fine) or my internet history? I hope he didn’t as it’s just embarrassing :( I went on dating sites before I found a girlfriend and I’d rather him not see that also on top of that I brought my GF a sort of erotic lingerie. I’m so embarrassed. Is it possible for engineer to see what I search?
It depends on which devices he had access to. If he was using your computer, he could potentially access your full history, but you would’ve been able to see him do it.
If he was just using your router, it would be highly unlikely he was able to review your history. However, if you’re a high-value target (someone trading with bitcoins or something like that), an hostile party could pretend being from the ISP to try to infiltrate your network.
