Security Researcher Detected: You might have ended up here because your site vulnerability scanner found something interesting. Hi! I'm a security engineer and I'm having a good time interacting with the people and bots that are interested in information security.

You will hopefully find this site is well-secured and I'm not interested in being hacked. I'm interested in learning about how people try to hack me, though.

What is this endpoint?

HNAP1/

Home Network Administration Protocol endpoint, targeted by router worms and IoT botnets

What an attacker could do

A reachable HNAP endpoint exposes D-Link/Cisco router management actions; known HNAP flaws (e.g. command injection, auth bypass) let worms like Mirai-variants execute commands and enroll the device into a botnet.

How to defend it

Disable HNAP/remote management on the device, block the endpoint at the WAN firewall, and apply vendor firmware updates that patch HNAP command-injection vulnerabilities.
