Macbook Pro 2011 15" OS 10.7.5 I've had some security issues as of late. Aside from Little Snitch and Wireshark usage, I discovered that a device was added to the System Preferences => Network as a "modem" if I recall correctly (usually the left window shows WiFi, Ethernet and Firewire). I promptly removed it - it was a knee-jerk reaction. It was a Samsung something or other. Only after did I start using Little Snitch and Wireshark to see if I could locate the intrusion and potential traffic. Anyhow, to make this short, I will omit extraneous details... What I am wanting to do, if possible, is to search any log files, system or otherwise, to see if I could locate an instance of this intrusion, this device being added. Just in case I need proof that another device accessed my internet via illegal means, should the information they surfed online might be illegal or warrant investigation of ME. Thank you - please let me know if you need any other information from me.
