🚨 ANTHROPIC JUST PUBLISHED A 36-PAGE SECURITY GUIDE THAT BASICALLY TELLS YOU TO STOP TRUSTING YOUR OWN AI AGENTS.
If you run agents on Claude Code, MCP servers, or automation tools, pay attention.
The attack timeline has collapsed.
AI models compress the gap between a vulnerability and a working exploit from months to hours, for mere dollars.
Agents introduce new autonomous risks, from tool poisoning to context memory manipulation.
The most useful idea in the guide is Anthropic's new security test:
Does a control make an attack impossible, or just tedious?
Automated attackers have unlimited patience. They will grind straight through friction like rate limits and 2FA. To defend at the speed of AI, you need hard barriers and automated defensive operations.
Here is how Anthropic says you should lock down agents:
→ Treat static API keys as compromised. Use short-lived tokens that expire in minutes.
→ Apply "Least Agency": explicitly limit what each tool can DO.
→ Sandbox agents that process untrusted inputs like emails and web pages.
→ Scope permissions dynamically per task, not permanently.

Today we're announcing LevelUp: a free, four-week training program that takes people with no prior experience and prepares them to work as fiber technicians on data center construction sites across the US.
We built this program with CBRE because the fiber technician field, and the broader construction industry, is facing a nationwide shortage at a time when data center demand is higher than ever.
How it works:
🔧 Classroom instruction, hands-on labs + team activities covering transferable technical skills
🎓 Graduates have the opportunity to work at Meta's US construction sites through our contractor network
🤝 Open to everyone from recent high school grads to mid-career professionals
Since 2010, Meta's data center projects have supported 30,000+ skilled trade jobs during construction + 5,000+ permanent operational roles. LevelUp is about building the pipeline to keep that going.
