... ...But even if a hacker remotely opens a port on your router, they still need to know your computer's local IP address, what services are running on your computer, and an additional exploit or attack vector to get into those services. It's not a "1 packet = destruction" type deal that article implies....
(still trying to learn)...if a hacker uses this vulnerability to get past the router, what damage can they do? I'm guessing that if someone is sophisticated enough to figure out how to get past the router, finding an IP address (responding to your comment above) doesn't seem too taxing. What can they do to your computer? Thanks!
