Botnet infecting 100K routers, using them to send spam

Has your router been infected and taken over by spammers to send spam?

A flaw in Broadcom-based routers (first discovered in 2013) that exploits a flaw in the UPnP protocol is being used to infect over 100,000 home routers and hijack them to send out spam. The list of routers is pretty long and will be included at the bottom of this post.

What can you do? If you are comfortable, logging into your router and performing a firmware update might be sufficient, but this depends on your router manufacturer having released an update since 2013 to address the issue. The procedure to update a router's firmware will vary from brand to brand and model to model... if your router was supplied to you by your ISP (especially if you are leasing it from them), you might be able to get your ISP's tech support to take care of this for you. Barring that, you could alternatively disable UPnP on your router. This could affect some applications so you might have to take steps to allow certain applications to work on your internet connection via manually setting up port forwarding.

If your router is on this list and you would like assistance from me, please contact me to set up an appointment.
