So, I got home tonight and my mom told me that 4 hours ago she was called about messages that her computer was sending that indicated trouble.... Well, you know how the rest goes. The only reason she mentioned it to me was that they were calling her back since she couldn't pay them the money until I got home. I just yelled something at them and hung up.
I checked her computer and "showmypc" was running. My kneejerk reaction was to exit it & shut off her wi-fi access. Then in (possibly) a compete panic I turned off our router & modem just because I didn't want any network access.
Now that I've had a chance to calm down... I've connected us to the outside world again. But I'm wondering if there is a way to:
1) Find out what they were accessing in the 4 hours they were connected to my mom's laptop.
2) The likelihood that they could've accessed anything else on the network through that program.
3) Any measures that I should take in the aftermath.
I've been studying for my Security+ certification but it's just skimming so much of the surface that I feel like it's done more to alarm me than to make me feel competent at securing my network.
Any ideas from you awesome folk would sure help.
