Military used GPS to distribute cryptographic keys

🔍 Steven Murdoch uncovered that U.S. military satellites have been broadcasting hidden codes via public GPS for nearly two decades, effectively turning each satellite into a covert distribution channel. He identified synchronized transmissions across all 31 operational satellites on May 26, 2011, matching the rollout timeline of the military’s Over-the-Air Distribution (OTAD) and Over-the-Air Rekeying (OTAR) systems. This mechanism allowed remote rekeying of military GPS receivers, replacing manual key distribution.

AI-driven worm shows autonomous host-level exploitation

🧩 Researchers at the University of Toronto built and tested a proof-of-concept self-replicating worm driven by a locally hosted open-weight large language model. In isolated experiments on a deliberately vulnerable 33-host network, the agent identified dozens of vulnerabilities, gained elevated access across most targeted hosts, and autonomously replicated to a majority of the network without using any commercial AI API. The team highlights how runtime reasoning and ingestion of fresh advisories break single-CVE patching assumptions and argues containment must focus on host and network controls rather than vendor API measures.
