Hydrat Project Builds Automated WireGuard Gateway for Resilient VLESS and Tor Routing

A developer has introduced Hydrat, an automated WireGuard gateway designed to maintain connectivity when VLESS servers become blocked or degraded. The project allows users to keep a single WireGuard profile on phones, laptops, and routers while the server handles proxy selection and failover.

The gateway accepts VLESS links, subscription feeds, and Tor bridges through an admin panel. Candidates undergo preliminary and full testing that checks access to Cloudflare, YouTube, ChatGPT, OpenAI API, and Telegram services, including UDP performance. Up to 10,000 candidates can be stored, with a working pool limited to 200 high-quality routes.

Active monitoring detects outages through fast HTTP and DNS probes, while a separate QoE loop measures time-to-first-byte and throughput against historical baselines. Routes enter degradation status after three poor results out of five and recover only after four good measurements. Two confirmed failures within a 20-measurement window also trigger alerts.

Client assignment uses weighted rendezvous hashing for initial selection. Planned route changes require a sustained 30 percent advantage, at least 30 minutes on the current path, and confirmation across three checks. Failover prefers pre-assigned backups before scanning the pool, and transport-level blocking occurs only when no viable alternative remains.

Network changes are applied sequentially: a new Xray outbound is created first, nftables rules are updated next, and old exits are removed last to avoid transient client disconnection. Separate counters ensure that only newer test results update route state.

The service runs in Docker, supports obfs4 and webtunnel Tor bridges, and preserves the last applied routing plan across restarts. The author notes that the server must remain reachable via WireGuard and therefore recommends placement within Russian jurisdiction.

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.

Free Ad Blocker for iPhone, Android, and Desktop Uses DNS Parsing Without Libraries and Skips YouTube Influencer Ads From the First Second

A new free ad-blocking solution has been released for iPhone, Android, and desktop platforms. The tool relies on a lightweight DNS parser that operates without external libraries. It includes a dedicated mode for users who already run VPN connections. An accompanying browser extension automatically skips sponsored segments in YouTube videos, even when the advertisement begins at the zero-second mark. The developer describes the technical challenges encountered after launch and the fixes applied to maintain compatibility across operating systems. The project emphasizes user privacy by avoiding unnecessary data collection and third-party dependencies.

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.
