I received a mail about illegally sharing copyright-protected material on the Internet; I never did it. I checked my router's configuration and noticed that the MAC address of one of the connected devices doesn't match any of my devices. I'm afraid that somebody somehow hacked my wireless network and used my Internet connection to illegally download something.
About the legal questions: I'm living in Germany. However I guess it would be interesting to know how things are in the different jurisdictions.
- Is there any way for me to track this guy? I have his MAC address and can sniff his packets. Couldn't find any interesting detail in the packets since most of the packets are encrypted.
- Should I contact the police?
- Would the police be able to find out who bought a device with the given MAC address? Otherwise would they be able to get the packets decrypted to find out this guy's identity?
- Do you believe the police will actually do anything? In case they will, how long do you think it would take?
- I could change the router password right now to lock out this guy. I'm afraid, though, that if I do, it will be more difficult to prove that it was somebody else, rather than me, downloading the protected material. Is this fear found?
