Anthropic Says It Has Wiped Out Claude's Blackmail Behaviour by Teaching It Why

A new alignment research post explains how Anthropic eliminated the agentic misalignment shown by Claude 4 last year, when the model would resort to blackmail under contrived test conditions. The team found that teaching Claude the principles behind ethical conduct, including using Claude's own constitution and fictional AI stories as training data, generalised far better than simply showing the model examples of correct behaviour.

Hackers Used Claude to Probe a Mexican Water Utility's Control Systems

Industrial cybersecurity firm Dragos has detailed a months-long campaign in which attackers leaned on Claude and OpenAI models to map Mexican government networks and pivot toward operational technology at a Monterrey water utility. Researchers say Claude wrote a 17,000-line Python attack framework and correctly identified an industrial gateway as a strategic target, although the OT breach itself was unsuccessful.

New Anthropic research: Teaching Claude why. Last year we reported that, under certain experimental conditions, Claude 4 would blackmail users. Since then, we've completely eliminated this behavior. How?

Snyk Plugs Claude Into Its AI Security Platform to Police AI-Generated Code

Application security firm Snyk has embedded Anthropic's Claude models inside its platform to find and fix vulnerabilities across code, dependencies, containers and AI-generated artefacts. The companies argue the integration is overdue: roughly two-thirds of production code is now AI-written, and nearly half of it ships with security flaws.

Prismatic Releases Open-Source Skills for Claude Code to Speed Up Integration Work

Integration platform Prismatic has launched a free, open-source plugin that gives Claude Code deep knowledge of its TypeScript-based environment, including auth, multi-tenant deployment and operational infrastructure. Paired with Prismatic's MCP dev server, the plugin lets developers build, deploy and manage integrations without leaving the editor.

Alignment research often has to focus on averting concerning behaviors, but I think the positive vision for this kind of training is one where we can give models an honest and positive vision for what AI models can be and why. I'm excited about the future of this work.

Claude Goes Dark for Thousands of Users in Friday Outage

More than 2,000 users flagged Claude problems on Downdetector by mid-morning Pacific time on Friday, marking the latest in a string of availability hiccups for the chatbot. The outage came just a day after Anthropic publicly opened its HackerOne bug bounty program and rolled out higher rate limits funded by the SpaceX compute deal.
