The fiber running to your house speaks a protocol (GPON) that assumes the physical network is trusted. That assumption breaks in interesting ways when a curious hacker with home-lab gear starts listening.
In "gpwn: Wiretapping Fiber ISP Deployments From the Comfort of Your Home", presented Wednesday, August 5 at 2:35 p.m., Rithwik Jayasimha and Rithvik Vibhu show exactly how far that breakage goes.
Speakers:
- Rithwik Jayasimha — Co-Founder, Lagrange Point
- Rithvik Vibhu — Co-Founder, Lagrange Point
gpwn looks at GPON fiber deployments (the passive optical networks ISPs use for fiber-to-the-home) and shows how much an attacker can observe or abuse from an ordinary subscriber position, effectively wiretapping ISP fiber infrastructure from home.
It's classic curiosity-driven hardware/protocol hacking on infrastructure most people never think about but everyone relies on.
The pair are hardware hackers and open-source tinkerers (they're also the duo who famously geo-unlocked AirPods Pro 2 to work as hearing aids in India).
Vibhu's open-source work spans DNS/DNSSEC, DANE, and decentralized-internet projects, all on his GitHub. The pair post their experiments on Lagrange Point's Substack.
If you like protocol reverse engineering or ISP-scale hardware, this is a fun, high-curiosity pick.
What's the most surprising thing you've found on your own fiber line?
