- The talk 'We are currently clean on OPSEC: The Signalgate Saga' is scheduled at DEFCON on Saturday at 4pm in LVCC - L1 - EHW3 - Track 5.
- The saga involves former national security advisor Mike Waltz accidentally adding a journalist to a war crimes Signal group with senior Trump officials.
- Defense Secretary Pete Hegseth posted 'We are currently clean on OPSEC' in the group, while Waltz was later photographed checking Signal messages under the table.
- Waltz was actually using a knock-off app called TM SGNL, made by TeleMessage, founded by a former Israeli intelligence officer.
- TeleMessage was hacked twice: first exposing plaintext messages, then exfiltrating hundreds of gigabytes of data before going offline.
- The talk covers the journalist's inclusion, Congressional lies, TeleMessage's history, analysis of TM SGNL source code proving false end-to-end encryption claims, the exploit used to extract data, and analysis of memory dumps full of chat logs.
- A book signing for 'Hacks, Leaks, and Revelations: The Art of Analyzing Hacked and Leaked Data' will be on Sunday at 11am at the exhibit hall.
