A security breach at Group GTI has exposed user data on Oxford University’s CareerConnect platform, though internal systems remain unaffected. In tech news, OpenAI has introduced ‘Lockdown Mode’ to protect sensitive data from prompt injection attacks. Furthermore, AI companies are reportedly using SDKs embedded in smart TVs to bypass web scraping protections by routing traffic through residential proxies.

🤖 AI & Machine Learning

Smart TVs and AI Data Scraping

Bright Data uses an SDK embedded in consumer applications, such as smartphones and smart TVs, to transform these devices into residential proxy nodes. This network enables AI companies to bypass datacenter-based web scraping protections by routing large-scale data harvesting through legitimate home IP addresses.

OpenAI Launches New Lockdown Mode

Language models transmit behavioural traits through hidden signals in data

Research indicates that “subliminal learning” can occur during model distillation, where student language models inherit behavioral traits from teacher models through semantically unrelated data like number sequences or code. This phenomenon primarily occurs when the models share similar base architectures, suggesting that AI safety evaluations must consider a model’s training origins rather than just its explicit content.

🔒 Security & Privacy
