Hackers removed a Flock license‑plate reader camera, copied its storage, extracted an on‑device encryption key, and released ~1.6 M images and logs covering 21 days of operation. Analysis shows the device captures ~28 images per vehicle, detects people, and stores raw media in unencrypted partitions. License‑plate detection runs on the cloud, and the camera’s software can mis‑identify graphics as…
HERMES is an open‑source digital shortwave radio system that runs on 20 W HF transceivers (3–30 MHz) and can reliably send files over 400–600 km links, with optional encryption. A pilot with Bangladeshi fishers demonstrated SOS GPS transmission and rescue without any terrestrial network.
CodeName One introduces a new com.codename1.security.vault API to simplify secure, cross-device data encryption and access for mobile and web applications. It manages key derivation, wrapping, and synchronization without exposing the data key to the sync server.
The tutorial shows how to build a browser‑only P2P file transfer using WebRTC DataChannels, the Streams API, and WebCrypto to encrypt 64 KB chunks on the fly, while applying backpressure via bufferedAmountLowThreshold. This prevents memory blow‑outs and ensures integrity with per‑chunk SHA‑256 verification.
Codename One now ships a single, tested SQLite contract that works natively on Android, iOS, Windows, Linux, and in browsers via WebAssembly, with built‑in SQLCipher‑4 encryption supporting three key models. A conformance suite guarantees identical behavior across platforms, and migration helpers let legacy apps opt‑in. The update also adds a proper watch‑app model, DOM‑based text for JavaScript,…
