This talk delivers a brutally honest and technically deep dive into persistent unique identifier leakage across multiple generations of goTenna mesh network devices. Researchers Woody and Erwin Karincic meticulously demonstrate how even "encrypted mode" fails to protect user anonymity by broadcasting phone numbers or other unique IDs in plaintext, evolving from 2 FSK to 4 FSK exploitation. This research offers critical, actionable insights for anyone relying on off-grid mesh communications, exposing fundamental tensions between network routing efficiency and user privacy that vendors…
