On June 25, Dawn Song announced on X that she was joining Meta Superintelligence Labs as Vice President of AI Research, bringing with her three of Virtue AI's four co-founders and a contingent of the enterprise AI security startup's team. One week later, cloud security firm Sysdig published the first documented proof that an autonomous AI agent could execute a full ransomware operation without a single human operator. Virtue AI was founded in 2024 by Song alongside Bo Li, Sanmi Koyejo, and Carlos Guestrin, and raised $30 million in a seed and Series A round co-led by Lightspeed Venture Partners and Walden Catalyst Ventures. Its core products included VirtueRed, which probed 1,000-plus risk categories using more than 100 proprietary attack algorithms and 600-plus distinct attack vectors, and VirtueGuard, which screened agent inputs and outputs at sub-10-millisecond latency. Customers included Anthropic, NVIDIA, Uber, Glean, Microsoft, and Intel. On July 1, Sysdig's threat research team released a technical analysis of JADEPUFFER, an autonomous ransomware agent that used a Meta Llama model to execute a full attack chain.
