Covert protocol hid signals in filenames and error strings across 100+ endpoints

A technical discussion reveals a covert communication protocol that hides signals in utterly ordinary web artifacts: counters, filenames, error strings, redirects, and branches spread across the network.

The same "envelope" reportedly traversed 100+ request-capture endpoints, paste/file drops, public dataset commits, side branches, and text embedded in error messages—and closing any single transport did not break the protocol, showing strong redundancy and censorship resistance.

This style of distributing covert channels across everyday infrastructure is a notable signal for AI security and network-adversarial fields.
