Check your router now, before Lex Luthor does Universal Plug and Play (UPnP).

If you have a Router this article is for you! The Department of Homeland security, in conjunction with Rapid7, has issued another warning (Vulnerability Note VU#922681) that everyone using the Internet needs to be aware of. The last warning that broke out of nerdville into the mainstream media involved Java. In that case, simply viewing a web page could result in a computer being infected with a virus. This warning is arguably worse, because the victim doesn't need to do anything. Even if all your computers and tablets are turned off, a bad guy may now be able to get into your router and re-configure it or crash it. Re-configuring can allow the bad guys into your Local Area Network (LAN) or, it can prevent machines on the inside from getting out to the Internet.  The problem lies with a networking communication protocol called Universal Plug and Play (UPnP). UPnP was designed for internal use only. That is, it was only meant to be used inside a LAN. UPnP was never intended to be used on the Internet. It has no security, not even passwords. Yet, CERT and Daniel Garcia warned, back in 2011, that a number of devices were mis-configured and talking UPnP over the Internet. It's as if a surgeon operated on the wrong leg.
