Internet Exposure Test
This Internet probe sends up to ten (10) UPnP Simple Service Discovery Protocol (SSDP) M-SEARCH UDP packets, one every half-second, to our visitor's current IPv4 address (10.1.1.1) in an attempt to solicit a response from any publicly exposed and listening UPnP SSDP service. The UPnP protocols were never designed to be exposed to the public Internet, and any Internet-facing equipment which does so should be considered defective, insecure, and unusable. Any such equipment should be disconnected immediately.
Is now being queried:
THE EQUIPMENT AT THE TARGET IP ADDRESS
ACTIVELY REJECTED OUR UPnP PROBES!
(That's good news!)
There is no question whether hackers are, in fact, currently sweeping the Internet for the presence of exposed and vulnerable consumer Internet routers in order to gain access to the private networks residing behind them. Just such hacking packets are now being detected across the Internet. Scanning is underway and the threat is real.Whenever changes are made to your network configuration, whenever you update your router's firmware, and also from time to time just to be sure, you should consider re-running this quick test to confirm that your Internet-facing equipment is continuing to ignore all attempts at its subversion though the Universal Plug n'Play (UPnP) protocols.
|It's natural to wonder what other results might have been shown if your Internet equipment were different. So to satisfy that curiosity, here are three sample screens showing each of this test's three possible outcomes:|
Here's what you need to know about Universal Plug n' Play (UPnP):
|The Security Now! podcast episode (#389) which immediately preceded the addition of this UPnP exposure testing facility, is available as a video on YouTube, or as downloadable high or low bandwidth audio. During that presentation, I explain to Leo and the podcast audience exactly what HD Moore and Rapid7 discovered during their comprehensive scanning the Internet during the second half of 2012, and I explain what it means for those whose Internet routers are exposing this privileged management interface:
