This question already has an answer here:
So here I am, sitting at my computer screen on the one day of the week I stayed home from work, checking messages on my phone, when out the corner of my eye I see a browser page being opened. It was PayPal. Luckily for me, I'm not so careless to stay logged-in. Then I noticed a TeamViewer session is running. I of course immediately disabled it and shut down TeamViewer, changing my password in the process. Looking through the logs, there indeed was an incoming connection, and fortunately for me, it seems to have been the first time.
I already contacted TeamViewer support and I am currently waiting for their reply. However, from what I can gather by the logs, they contain the incoming connection's UUID. Can this somehow be used to find more information about the culprit?
