Cisco Talos disclosed CLOSEDQUORUM, which it describes as the first reported fully autonomous multi-model AI command-and-control implant running with no human operator. Talos also released CAIRN, a toolkit for tracking AI-integrated malware, noting such malware went from optional LLM helpers to autonomous C2 in a single year.
A six-mathematician team including MIT's Bjorn Poonen and Colorado State's Rachel Pries used multiple AI agents to search M23's symmetry combinations. The work produced an explicit degree-23 polynomial whose Galois group is M23, closing the final open sporadic case of a decades-old problem.
Snorkel AI raised $350 million led by Insight Partners and S32, valuing it at $3.5 billion, nearly triple its May 2025 mark. CEO Alex Ratner said annualized revenue passed $350M, up from about $20M a year earlier, on demand for complex AI training data.
