![]() ![]() Today, any home appliance - TV's, DVD players, game consoles, IP cameras, printers, fax machines, and you-name-it, includes support for UPnP.UPnP has been provided and enabled by default in consumer Internet routers since 2002 or 2003. ![]() Here's what you need to know about Universal Plug n' Play (UPnP): 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. Scanning is underway and the threat is real. Just such hacking packets are now being detected across the Internet. 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. Thus hackers will know that some equipment exists at this IPv4 address-though they will have no idea what it is, and they will be unable to attack it though UPnP SSDP subversion because it is proactively replying that there is no active service available at its UDP port 1900. This equipment is not fully “stealthful” inasmuch as it did respond to our probing. Any such equipment should be disconnected immediately. 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. 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.
