I recently downloaded 2 compressed files (.zip and .rar) from a really unreliable and untrusted source while using a browser integrated VPN. My antivirus didn't notice anything but I am curious if it is possible for a compressed file to contain malicious code that could potentially reveal my real IP address by communicating with a server (or something, I am not a programmer :P). I know IPs are not something you really need to hide (since every site toy visit has it on it's logs) but I would like to know if it is possible from a technical point of view.
Thanks!
