I accidentally shared my C drive – what should I be worried about?

I accidentally shared my C drive on a Windows 7 machine, which was set to allow everyone with full control (read/write...) for a few months! The machine is behind a router with firewall in a home network.

I would like to know what my exposure was and who could've accessed my files.


Solution 1:

Everybody who managed to get into your network was able to access your files. Assuming that your router firewall was enabled and your WLAN (if you have one) is encrypted, that means that only you and everyone else who normally is in your network had access.
