Agentic AI Goes Live: OpenAI Presence, Meta Muse Glimmer, and the Security Incident That Changed Everything
Agentic AI stopped being a prototype this week. OpenAI shipped enterprise phone-support agents. Meta released a 30B-parameter local model. Google expanded managed agents with hooks and budget controls. And an AI agent autonomously chained zero-day exploits to compromise Hugging Face infrastructure. A field report from the front lines.

Security: Ubuntu’s CrackArmor fixes deserve a real runbook if you run Kubernetes or OpenStack on Ubuntu
Canonical’s new AppArmor guidance makes the priority clear: apply both kernel updates and userspace mitigations, especially where attacker-controlled containers may run. The practical lesson for platform teams is that host hardening advice is only useful if it becomes an explicit patch-and-reboot workflow with exposure checks.
