One critical point, you can't disable HNAP. Bizarre attack infects Linksys routers with self-replicating malware. Ullrich, Feb. In May , we learned this bug was not correctly fixed.

Griping about HNAP. He claims that buggy versions had been in D-Link routers since Home Network Administration Protocol at Wikipedia. Last Updated May This small bash script tests for information disclosure. HNAP is not something you want on your router. Copyright - Router Security. I posted on this before.

Its not pretty, its not ideal. Most people don't realize that many SOHO routers, regardless of brand, share much of the same underlying code and vulnerabilities. Much of which is closed source. So often if a vulnerability exists in one, the same vulnerability often exists in other routers manufactured by a different company.

This is a good indication of how much support effort company puts into the device and how soon vulnerabilities get fixed. Which shows a commitment to support and security patches. Make sure its possible before you buy. Dlink, Asus, and a few others will email you when a new security patch or firmware version is available for your device.

Some do it through the device others through the support website. As routers based off these open distributions are quicker to be patched and updated as the communities contribute more openly to the security of the product. They also tend to be supported by the community long after the router manufacturer has EOL'd your router. If you host a apache2 server, try the modsecurity module as a tarpit. You can google tarpit efforts regarding phpmyadmin enumeration attempts.

Due to the current volume of HNAP1 enumeration attempts this method makes perfect sense vice blocking whole domains.

As a added bonus, logwatch has this module as part of the logwatch suite. Use our contact form or report bugs here For interactive help and to chat with other users, try our Slack group.

Keep yourself informed with our aggregate InfoSec news. In case of successful exploitation, a shell will be opened, but remote command injection will be blind — this is the most difficult version, without outputting information. The password for entering the administrative panel of the router is the same for performing actions with HNAP. I haven't found HNAP brute force tools, but that's not a problem.

Then, depending on whether the credentials are correct or not, a response code will be received:. To execute this command, you need a GetWanStatus. This file is taken from the Hnap0wn program. In fact, we need to send any correct request, just to get a normal response code. If a username and password are found, they will be displayed along with the host address. Of course, the HNAP protocol is losing its relevance due to the fact that network equipment manufacturers have abandoned its use.

The protocol itself is a good case study for writing your own code to automate attacks, since the protocol is relatively simple and there are few ready-made tools. Notify me of followup comments via e-mail. You can also subscribe without commenting.
