Summary

Between April 8 and May 21, 2026, a Russian-speaking operator linked to the Aurora ransomware group reportedly used Cursor Agent, running Anthropic's Claude Sonnet 4.5, to assist exploitation across multiple organizations. Researchers said some AI-directed tasks succeeded while others failed; independent reporting identified six affected companies but could not determine how much the AI facilitated each breach or whether all led to data theft or extortion.
