A cybersecurity newsletter covering three main topics: the national security and privacy risks of commercial geolocation surveillance tools like Webloc (sold by Penlink), which aggregates location data from 500 million devices and is used by U.S. law enforcement and foreign governments; a detailed case study of a single hacker using Claude Code and GPT-4.1 to breach nine Mexican government agencies and steal hundreds of millions of records; and brief news items including a U.S. disruption of a Russian GRU botnet, an FBI/Indonesian phishing network takedown, Google's Device Bound Session Credentials rollout in Chrome 146, malicious LLM proxy routers found in the wild, France's plans to migrate from Windows to Linux, and China's cybersecurity five-year plan. The author argues the U.S. should ban the sale of precise geolocation data entirely, not just regulate its use.
