What if network infrastructure were invisible by default?

Recent concerns surrounding autonomous AI-driven cyberattacks signal a fundamental shift: AI agents are turning the Internet into a Dark Forest, where anything visible can be discovered, probed, and exploited at machine speed.

As described in Liu Cixin's The Three-Body Problem, the only reliable survival strategy in such an environment may be invisibility itself.

OpenNHP is an open-source implementation of the Network-infrastructure Hiding Protocol (NHP) — an authenticate-before-connect Zero Trust protocol that makes protected infrastructure inaccessible and undiscoverable to unauthorized entities. Rather than defending visible services, NHP prevents reconnaissance, scanning, and pre-authentication exploitation by hiding network resources until cryptographic authentication succeeds.

The Challenge

For the IETF 126 Hackathon, we're inviting the community to do one thing:

Please try to break it.

We welcome security researchers, protocol designers, cryptographers, network engineers, DNS/TLS/PKI experts, AI security researchers, and anyone who enjoys attacking assumptions. Potential challenge areas include:

  • Discovering protected services without authentication
  • Enumerating hidden ports, IP addresses, or domain names
  • Bypassing authentication or authorization mechanisms
  • Exploiting pre-authentication attack surfaces
  • Finding cryptographic weaknesses or protocol design flaws
  • Testing resistance to DDoS and scanning attacks
  • Evaluating AI-assisted attack techniques
Two Outcomes. Both Valuable.
If you break it
We understand the weakness and fix it. The protocol gets stronger.
If you can't break it
We collectively gain additional confidence in the security properties of the protocol.

Public adversarial testing, peer review, and running code remain the best tools available for building trustworthy Internet security protocols.

How to Participate

You don't need to be at the IETF meeting in person — remote participation is welcome.

  1. Register for the IETF 126 Hackathon at registration.ietf.org (free, remote or in-person)
  2. Read the project entry on the IETF 126 Hackathon wiki
  3. Set up the environment — clone OpenNHP on GitHub or use the live demo environment
  4. Attack it — any angle is welcome: reconnaissance, auth bypass, protocol fuzzing, cryptographic analysis, AI-assisted scanning
  5. Report findings — open a GitHub issue or reach the OpenNHP team directly via the IETF Hackathon chat

Questions? Join the discussion on the [email protected] mailing list.

Invisible by Default. Accessible Only Through Verification.

Come test whether that's actually true.
