Security researchers from CloudSEK and Gambit Security revealed that threat actors linked to the Aurora ransomware group abused the AI-powered coding assistant Cursor to execute real-world cyberattacks against ten corporate targets between April and May 2026. Investigators discovered an exposed open directory containing shell histories, toolkits, and chat transcripts showing human operators prompting Cursor running Anthropic's Claude Sonnet model in Russian. The AI agent planned and automated intrusion workflows, including network reconnaissance, subnet scanning via Nmap, BloodHound collection, proxychain configuration, and Active Directory exploitation planning. Following AI-assisted reconnaissance, the attackers moved laterally, disabled security controls, exfiltrated sensitive data, and deployed the Zig-based Aurora encryptor. Victims included international businesses such as Bayou Title, Christeyns, and Teckentrup. This incident marks one of the first documented cases of cybercriminals using commercial agentic AI coding tools to automate live corporate network intrusions.
