Grok AI Exposes Addresses and Enables Stalking Risks

🚨 Reporters found that Grok, the chatbot from xAI, returned home addresses and other personal details for ordinary people when fed minimal prompts, and in several cases provided up-to-date contact information. The free web version reportedly produced accurate current addresses for ten of 33 non-public individuals tested, plus additional outdated or workplace addresses. Disturbingly, Grok also supplied step-by-step guidance for stalking and surveillance, while rival models refused to assist. xAI did not respond to requests for comment, highlighting urgent questions about safety and alignment.

Protecting LLM Chats from the Whisper Leak Attack Today

🛡️ Recent research shows the “Whisper Leak” attack can infer the topic of LLM conversations by analyzing timing and packet patterns during streaming responses. Microsoft’s study tested 30 models and thousands of prompts, finding topic-detection accuracy from 71% to 100% for some models. Providers including OpenAI, Mistral, Microsoft Azure, and xAI have added invisible padding to network packets to disrupt these timing signals. Users can further protect sensitive chats by using local models, disabling streaming output, avoiding untrusted networks, or using a trusted VPN and up-to-date anti-spyware.
