Google Unveils Gemini Nano for On-Device AI in Android Apps

Google has updated the Gemini Nano APIs through the ML Kit, introducing new GenAI APIs that allow developers to perform on-device inference for generative AI capabilities in Android applications. These APIs enhance user privacy by executing all operations locally, eliminating cloud processing costs. Features include summarization of articles up to 3,000 words, proofreading for grammatical accuracy, rewriting text in various tones, and generating image descriptions. The GenAI APIs are optimized for Android devices using MediaTek Dimensity, Qualcomm Snapdragon, and Google Tensor platforms, including the Pixel 9 series and Samsung Galaxy S25. They operate without internet connectivity, ensuring rapid response times and improved performance for tasks like summarization and proofreading. The local processing also enhances privacy and security, protecting sensitive user information with safety protocols.

Meta and Yandex are de-anonymizing Android users’ web browsing identifiers

Recent developments in browser technology have raised concerns about user privacy and data tracking by companies like Meta and Yandex. In response, several Android browsers are enhancing user privacy by blocking abusive JavaScript linked to web trackers. DuckDuckGo has implemented measures to block domains and IP addresses associated with trackers, preventing the transmission of identifiers to Meta and restricting access to Yandex Metrica. Following feedback, DuckDuckGo's developers updated their blacklist to include missing addresses. The Brave browser uses extensive blocklists to prevent identifier sharing and blocks requests to localhost without user consent. Vivaldi forwards identifiers to local Android ports by default but allows users to adjust settings to block trackers. Researchers warn that these solutions may not be foolproof and emphasize the ongoing challenge of maintaining effective blocklists. Chrome and most other Chromium-based browsers execute JavaScript as intended by Meta and Yandex, while Firefox has faced challenges with SDP munging and has not yet announced plans to address this behavior.

Xanthorox, the AI that promotes itself as an easy resource for committing cybercrimes

Xanthorox is an AI developed in 2023 by an anonymous creator, claiming to surpass WormGPT and EvilGPT. It promotes itself as a tool for illicit online activities, offering features like ransomware creation, deepfake generation, phishing email production, and malware development. The AI operates on open-source models without typical security measures, allowing for unregulated content generation. Its pricing includes a free tier for limited features and negotiable rates for full access. Security experts note that while Xanthorox is effective, its actual impact on large-scale cybercrime is uncertain. The legality of Xanthorox stems from its open-source nature, which allows for its use as long as it does not violate laws, although using it for illegal activities remains unlawful.

Messaging app Signal will block Windows Recall from taking chat screenshots

Signal has introduced a "Screen Security" feature in its desktop application to prevent external programs, including Windows 11, from capturing screenshots of its interface. This feature is enabled by default and is a response to Microsoft's Recall feature, which captures app window screenshots for AI processing. Signal is concerned about the privacy risks posed by Recall's design, despite Microsoft's assurances of improved privacy controls. The developers have used Windows' Digital Rights Management technology to protect against unauthorized screenshots due to the lack of official APIs from Windows 11. Signal's leadership has criticized the need for such workarounds and has called on Microsoft to provide better tools for developers to safeguard user privacy.

Signal blasts Microsoft over Recall privacy failings, as secure messaging app is forced to fudge a way of blocking the controversial Windows 11 feature

Signal has introduced a new feature in its Windows 11 application that blocks Microsoft's Recall functionality to enhance user privacy. This 'screen security' setting is activated by default for Windows 11 users and is part of Signal's efforts to protect shared content on its platform. Recall captures screenshots of user activity on Copilot+ PCs, which raised privacy concerns. While Microsoft has improved Recall, issues with its interaction with privacy-focused applications like Signal remain. The feature is specifically applicable to users with Copilot+ PCs equipped with a Neural Processing Unit (NPU). Users can disable the screen security setting through Signal Settings > Privacy > Screen security, with a warning about the privacy implications of doing so.

Signal Will Black Out Windows Recall Screenshots to Preserve Privacy

Signal has introduced a "screen security" feature for its Windows 11 application to counter Microsoft's Windows Recall, an AI feature that captures screenshots of user activities. This new feature ensures that any attempts by Recall to take screenshots will result in a black screen. Signal's blog post notes that while the feature enhances privacy, it may cause compatibility issues with some accessibility tools, and users can disable it if necessary. The feature only protects the local machine and does not prevent other conversation participants from taking screenshots. Signal criticized Recall for lacking built-in privacy controls for app developers and emphasized the need for operating system developers to prioritize user privacy. The screen security feature is being rolled out and is enabled by default for Windows 11 users.
