Back door in some routers.

[Shintaro]

Hi,

This is kind of old news, but people should be aware that there is a back door in some routers.
grc.com has a scan so that you can check if it affects you.

Thanks for the heads up Shintaro - it seems like there have been a lot of routers with a backdoor recently .

There is another tool to check your router: http://www.websec.mx/blog/ver/detector-puertas-traseras-websec

It looks like it was not fixed. There was a patch but they just enabled another way to get to the backdoor!
Basically by sending a specific packet to the router, the router will then open up and enable that port again.
HERE is the research.

Naughty naughty! That certainly makes an interesting (and scary!) read .

It seems as if they are so arrogant that they think that people will not check. This is the kind of thing that people love to check.
Makes you think, "What are they up to?"
