Universal Plug and Play or UPNP, is a feature that is supposed to make connecting networked devices easier for end-users. According to security experts, over 80 million unique devices responded to their public internet request.
Essentially, they sent out a question and over 80 million routers – e.g. the one in your living room, the one at your consignment store, etc. – responded. That’s not good, to say the very least.
It is recommended that you disable UPNP in your router immediately, if you have not done so already.
Log in to your router and locate the UPNP option – typically just a box you un-check. Make sure you have a backup of your router’s configuration before making any changes. You might need to reboot any devices connected to the network as well. Keep in mind, this could “break” any devices’ connections that were not manually setup and instead utilized the UPNP shortcut.
