Anthropic has disclosed that it blocked accounts tied to Iranian influence operations and users in northern Yemen who attempted to use Claude's coding tools to develop advanced guided weapons, according to circulating summaries of the company's latest security report. The details are striking not because state actors want Western AI — that was always going to happen — but because of how specifically they were caught trying to use it.
