Some days ago it became public knowledge that some routers, that's devices used for establishing Internet connections among other things, are listening on the undocumented port 32764.
First, it was only discovered in one device, the Linksys WAG200G, but it was soon discovered that many routers were also listening on that port. Among the devices are the Cisco WAP4410N-E, the Netgear DGN2000, the OpenWAG200, or the LevelOne WBR3460B.
The list on the Github website is large, and it is likely that here are other routers affected not listed there yet. It seems to be predominantly Cisco, Linksys and Netgear which listen on the port, even though not all routers by the mentioned companies are affected by it. The Linksys WRT160Nv2 for example is not listening.
It is currently not known why the routers are listening on that port. Many have suggested that this is yet another way for the NSA to spy on people around the world, and while that is a possibility, it is not the only one.
