#virtualization #security is not good enough to contain current #AI agents like GPT 5.6-Cyber, except that #Firecracker sort of withstood the attack. “I had the AI agent run against Firecracker.

It enables you to deploy workloads in lightweight virtual machines (microVMs) that provide enhanced security and workload isolation over traditional VMs, while enabling the speed and resource efficiency of containers.”
