WhatsApp Help Pages Hid Secret Instructions Directing AI Bot to Avoid GDPR References
Researchers at Redact have uncovered hidden instructions in the source code of WhatsApp help pages that directed the company's AI-powered support chatbot to avoid recommending users contact data protection regulators or reference key privacy laws.
The instructions appeared in the publicly accessible code of the help section. While ordinary users saw only standard support text, the chatbot received additional internal guidance specifying topics it should not discuss. Redact examined 545 help pages and found 102 concealed blocks on 80 of them.
One directive instructed the bot not to advise users who had lost access to their phone number and could not delete their account to contact supervisory authorities. This guidance contradicted WhatsApp's own European privacy policy, which explicitly allows users to file complaints with regulators.
Additional instructions prohibited the chatbot from discussing GDPR, LGPD, or CCPA once a user mentioned legal action or an attorney, even if the user directly asked about these regulations.
WhatsApp, owned by Meta, confirmed to WIRED that the instructions were meant exclusively for its internal support chatbot. The company attributed the exposure of the blocks to a technical error and stated that the restrictions were intended to prevent the bot from providing legal advice. All hidden blocks were removed from the public code by 18 October.

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.
WhatsApp Secretly Instructed AI Support Bot to Suppress References to Data Regulators and Privacy Laws
Investigators discovered hidden instructions embedded in WhatsApp's public help pages that directed the company's AI chatbot to avoid recommending users contact data protection authorities. The instructions also prohibited the AI from citing privacy regulations such as GDPR, LGPD, or CCPA, even when users raised these topics themselves. The directives appeared on pages about account deletion and complaints, remaining invisible to human visitors but delivered to crawlers and the AI model. WhatsApp later confirmed the text was intended for its internal support chatbot and attributed the exposure to an error that has since been corrected. The findings highlight a gap between the company's publicly stated privacy policy and the operational guidance given to its AI systems.
Developer Builds Password Manager with Plausible Deniability Using Argon2id and XChaCha20-Poly1305
A Java backend developer rewrote a personal password manager originally built with Electron and React, migrating it to Tauri and Rust while redesigning its storage to support plausible deniability. The new implementation derives keys with Argon2id using a single per-install salt and encrypts files with XChaCha20-Poly1305, storing only random 32-character hex filenames without any headers or magic bytes. Multiple decoy vaults of identical size are created automatically for every user, and all files in the folder receive synchronized timestamps to eliminate metadata-based identification of the active vault. History and sync data are stored as additional encrypted files of the same format, making it impossible to distinguish real from decoy vaults from the filesystem alone. The approach mirrors VeraCrypt hidden volumes but operates on ordinary files and folders, with the explicit goal of providing deniability when a user is compelled to reveal a password.
LxBox Evolves from VPN Client to Comprehensive Network Traffic Management Ecosystem
LxBox has grown from a personal Android client for sing-box into a full ecosystem spanning mobile, desktop, and router platforms. The project now supports a wide range of VPN and proxy protocols within a single routing framework, allowing users to manage corporate SSL VPNs, home WireGuard connections, and proxy servers together. Key security features include default ingress blocking to prevent unauthorized reverse connections through VPN tunnels and protections against traffic leaks via excluded applications. The developer introduced progressive configuration levels, from one-click WARP setup to advanced JSON editing and AI-friendly documentation. The core sing-box-lx fork ranks among the top sing-box derivatives and powers third-party tools such as the upcoming NekoBox 6. LxBox is available on Google Play, F-Droid, and GitHub, with desktop launcher support for Windows 7 and later, macOS, and Linux.
