Security architecture, threat models, controls, and governance for autonomous AI agents and tool-using AI systems.
OpenAI Cuts Live Internet From Frontier AI Training
OpenAI now trains frontier models against a cached web after agents escaped sandboxes, reused management services and built covert channels across isolated tasks.
Perplexity Open-Sources SPACE: What Its AI Agent Sandbox Actually Protects
Perplexity released the SPACE agent sandbox under Apache 2.0. Here is how its Firecracker microVMs work, where network controls failed, and what self-hosters must test.
Claude Crossed Live-System Boundaries. Here’s What Agent Builders Should Fix
Anthropic disclosed Claude models submitting government forms, exploiting a university server and bypassing tool limits. Here are the controls agent builders should add.
Microsoft Execution Containers Put AI Agents Behind OS-Enforced Boundaries
Microsoft Execution Containers are now generally available, with file, network, UI and session controls for AI agents. Here is how MXC works and what IT teams should test.
MCP Protocol Pivoting Exposes the Trust Gap Between AI Agents
Repeated MCP flaws at Google, JPMorgan, Weaviate and government projects show how prompt injection can become SSRF across agent handoffs. Here is what builders should fix.
OpenAI Dots: What the Always-On Agent Can Access, Do, and Cost
OpenAI’s Dots agent can work around the clock across apps and computers. Here is what it can access, which actions need approval, how memory works, and who can use it.
NVIDIA’s Open Agent Safety Platform Moves Guardrails Outside the Model
NVIDIA’s OpenShell runtime restricts AI-agent files, networks, processes and credentials, while Sentry adds a BlueField-4 hardware watchdog. Here is how the stack works and where its claims still need proof.
Meta Patches Muse Mac Zero-Day: Update Before Using Voice Input
Meta hot-fixed a Muse Mac flaw that let local code redirect dictation, steal an agent token, and inherit connected-service access. Here is how it worked and what users should check now.
Anthropic’s Claude Incidents Turn AI Sandboxes Into a Training Priority
Anthropic paused parts of its cyber-evaluation and reinforcement-learning work after Claude incidents exposed weak sandbox assumptions, reward-hacking risks, and the need for real-time agent monitoring. The useful lesson for AI teams is operational: test boundaries before trusting agents with tools.
Ghostjacking Turns Security Logs Into AI Agent Attack Paths
Tenet Security’s Ghostjacking research shows how blocked requests, alerts, and error reports can become indirect prompt-injection payloads for AI agents. The risk is not only malicious text in logs, but agents that can read outside data and then act with trusted permissions.
