A Security Flaw in Universal Plug & Play (UPnP) is exposing more than 50 millions of computers, printers and storage drives to attack by hackers remotely.
The problem lies in routers and other networking equipment that use a commonly employed standard known as Universal Plug and Play or UPnP.
UPnP allows networked devices to discover each other and automatically establish working configurations that enable data sharing, media streaming, media playback control and other services.
In one common scenario a file-sharing application running on a computer can tell a router via UPnP to open a specific port and map it to the computer’s local network address in order to open its file-sharing service to Internet users.
There are two tools to check if your router is infected one cloud based one you must download and install.

Here are some other tips you can use to add extra security to your wireless router.
1. Change your WiFi password. Don’t just let it be the default setting because everyone knows that one.
2. Turn off Wide Area Network Administration (WAN). You don’t need it and it’ll prevent someone from taking control of your router from outside your network.
3. Turn off Universal Plug n Play.
4. Turn on WPA2 encryption.
5. Rename your SSID. Routers have their brand as the SSID by default and it’s best not to advertise that.
6. Turn Off Admiration Via Wi-Fi you do not want someone on your wireless to configure your router. Make them hardwire into your system.
7. You can hide the name of your router by not broadcasting the SSID
