Explore a security research presentation from DEF CON 32 that investigates vulnerabilities in goTenna Pro radio devices, which are designed to create off-the-grid encrypted mobile mesh networks. Learn how researchers discovered methods to fingerprint and track encrypted messages, intercept and decrypt AES-256 encrypted communications, and inject messages into existing mesh networks despite manufacturer security claims. Discover the testing methodologies used, witness live exploitation demonstrations, and understand the operational implications of these security flaws. Gain insights into safer usage practices that minimize compromise risks, access open-source tools developed during the research, and learn about the collaborative efforts with goTenna to address these vulnerabilities.
