Reversing your own router with Claude reveals ISP can see every site you visit
kristoph · x · 2026-10-26
A developer used Claude to reverse-engineer his home Wi-Fi router and uncovered multiple privacy issues:
- The router keeps a list of 29 devices that ever connected, with visibility into new joins
- His ISP can remotely access the router anytime via a hidden channel in the connection name, with no way to disable it
- Every site visited was looked up in plain text through the provider
- The provider's TV box app kept sending data even when the TV was off
Commenter kristoph recommends running your own router: build a multi-NIC machine from scratch on a minimalist Linux distro, ideally with an AI agent helping with setup. Roughly 1 billion devices may be affected.
