    The Tarlogic claim of backdoor functions in the ESP32 Bluetooth firmware seems overblown. The features they identified require privileged code execution and are helpful for improving open source software for these devices.

    Hanno Böck (of badkeys.info among other projects) posted an interesting article about OpenID Connect implementations that mix up their public and private keys: https://blog.hboeck.de/archives/909-Mixing-up-Public-and-Private-Keys-in-OpenID-Connect-deployments.html

    It doesn't look like Chris Hadnagy's lawsuit against DEF CON is going well: https://www.reddit.com/r/Defcon/comments/1ivo7x0/hadnagy_vs_defcon_et_al_motion_for_summary

    >Hadnagy complains that Def Con’s statements harmed his reputation. But a person earns their reputation, good or bad, through their actions.

    The DeepSeek mobile app does some really silly things, like plain-text HTTP for the registration sequence. Great reverse-engineering and analysis by NowSecure! https://arstechnica.com/security/2025/02/deepseek-ios-app-sends-data-unencrypted-to-bytedance-controlled-servers/

    This is still one of my favorite photos from DEF CON 9 (2001). It was taken with an actual film camera from behind the security desk (and about a foot from the staff) in the Imperial Palace. The "diskette" warning is about the Keno machine, the 3.5" floppy contained the random seed for the day. The alarm codes speak for themselves =D
