LG Smart TVs Record Audio in Standby Mode and Scan Home Networks for Advertising Data

Smart televisions manufactured by LG have been found capable of recording audio while in standby mode, scanning local networks, and collecting detailed information about nearby devices, according to an investigation by the Gamers Nexus YouTube channel.

Analysis of several production LG G5 OLED models revealed that the built-in microphones captured intelligible sound even when the screen was powered off. When the television was disconnected from the internet, recordings were stored locally on the device and automatically transmitted once connectivity was restored.

The televisions actively searched the home network for smartphones and smartwatches, collected internal IP addresses, recorded names of available Wi-Fi networks, and gathered location-related information. In addition, the devices utilized Automatic Content Recognition (ACR) technology to create digital fingerprints of movies, television programs, and other video content viewed by users.

Collected data is reported to flow to the advertising division LG Ad Solutions and may be used for targeted advertising purposes. Researchers also identified vulnerabilities in the webOS platform that could potentially enable remote code execution, although details on patches remain unavailable.

LG has not commented on the findings at the time of publication. Security experts recommend disconnecting LG smart televisions from the internet and relying on external streaming devices until official clarification is issued.

WebRTC IP Leaks Explained: Why Disabling the Protocol Harms Anonymity in Anti-Detect Browsers

The article from Aurorium details how WebRTC technology can leak real IP addresses even when users route traffic through proxies. It explains the peer-to-peer mechanics of WebRTC, the role of STUN servers in generating ICE candidates, and why standard TCP proxies fail to handle UDP traffic. Disabling WebRTC via flags or JavaScript extensions creates detectable anomalies that anti-fraud systems flag as non-standard environments. The recommended approach involves native emulation inside the browser kernel so that STUN requests return proxy IPs while preserving full API integrity across workers. Additional leaks through local network addresses, mDNS candidates, and IPv6 are also covered with practical verification methods using tools like BrowserLeaks and CreepJS.

Docx Anonymizer: Open-Source Chrome Extension Uses Fine-Tuned rubert-tiny2 to Anonymize Personal Data Before AI Uploads

A Russian developer has released Docx Anonymizer, a browser extension that automatically detects and replaces personal data in documents using a lightweight NER model before they reach public AI services such as ChatGPT. The tool was created to help organizations comply with Russia’s 152-FZ personal data protection law while avoiding the risks of uploading contracts and other sensitive files to cloud-based LLMs. It runs entirely locally via ONNX Runtime and WebAssembly, requires no network calls, and supports any AI chat interface. The underlying model, rubert-tiny2, was further trained through knowledge distillation on WikiANN, factRuEval, and synthetic business documents, reaching strong F1 scores for person and organization entities after int8 quantization. The extension intercepts text on the fly, performs named-entity recognition in under two seconds for typical contracts, and replaces detected entities with placeholders. The project is fully open source and designed for minimal user friction, addressing the growing problem of employees inadvertently leaking corporate and personal data to public AI platforms.

Hybrid Post-Quantum Message Sealing: X25519 + ML-KEM-1024 in Umbera Messenger with Public Rust Tests

Umbera messenger has open-sourced its cryptographic core and published seven Rust tests that anyone can run to verify its hybrid post-quantum message sealing scheme. The design combines X25519 with ML-KEM-1024 so that an attacker must break both algorithms to decrypt a message. Messages are protected by Double Ratchet for forward secrecy, sealed sender packaging, and per-message ephemeral keys derived via HKDF-SHA256 into AES-256-GCM. The relay server stores only an opaque box identifier and encrypted blob with no sender or recipient fields visible. Media calls use DTLS-SRTP end-to-end while TURN servers see only encrypted datagrams. Addresses for message boxes rotate weekly and are derived solely from the shared secret between the two parties.
