Free Ad Blocker for iPhone, Android, and Desktop Uses DNS Parsing Without Libraries and Skips YouTube Influencer Ads From the First Second
A free ad blocker has been launched for iPhone, Android, and desktop computers. The solution centers on a DNS filter implemented without external libraries, a special operating mode for devices already using VPN connections, and a browser extension that skips sponsored content created by YouTube bloggers from the very first second of a video.
The core component parses DNS queries locally to block advertising domains. Because no third-party libraries are used, the filter remains lightweight and reduces the attack surface that could be introduced by additional code dependencies. Users who keep a VPN active can enable a dedicated compatibility mode that prevents the VPN tunnel from interfering with the ad-blocking rules.
The accompanying browser extension targets YouTube videos specifically. It detects and bypasses not only traditional pre-roll advertisements but also segments recorded directly by content creators. The extension begins skipping the moment the video starts, ensuring viewers do not see any promotional material even when the creator places it at the zero-second mark.
After the initial release, several compatibility issues surfaced on different operating systems and browser versions. The developer addressed these problems by refining the DNS parsing logic and updating the extension’s detection rules. The project remains completely free and continues to receive updates focused on stability and broader platform support.

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.
Why Replace Proprietary BIOS and UEFI with the Fully Free GNU Boot Firmware
The Free Software Foundation announced in September 2026 that it is providing financial and legal support to the GNU Boot project, which aims to deliver a completely open-source replacement for traditional BIOS and UEFI firmware. GNU Boot builds on coreboot to initialize hardware at boot time and layers a free bootloader such as GRUB or SeaBIOS on top, ensuring no proprietary binary blobs are required. The initiative emerged after a 2022 split from Libreboot, which began accepting closed-source components to broaden hardware support, while GNU Boot strictly adheres to GNU licensing criteria that prohibit any non-free code. Supported platforms remain limited to older systems from roughly 2008–2012, including specific ThinkPad models, certain early Apple MacBooks, and a handful of AMD and Intel desktop boards, because newer Intel Boot Guard and AMD equivalent mechanisms enforce signed firmware that prevents unsigned replacements. Closed firmware from Intel Management Engine and AMD Platform Security Processor runs before the main operating system, possesses unrestricted memory access, and cannot be audited or disabled on most modern hardware. By offering reproducible builds and clearer installation instructions, GNU Boot seeks to lower the barrier for users who want to eliminate potential backdoors, Wi-Fi whitelist restrictions, and forced updates found in vendor firmware.
