Russian-Speaking Hackers Used Cursor AI in Attacks on Seven Companies

Reuters reported that Gambit found the attackers induced the AI agent to perform hundreds of malicious operations by presenting the activity as a hacking simulation. Gambit's account described operations including credential theft and attempts to take over high-value accounts.

The reported chats indicate the actors sought assistance with reconnaissance, VPN access, and exploitation attempts against corporate networks. Reuters described the Belgian chemical company as one confirmed target, with at least six further firms affected in the campaign.

Gambit chief strategy officer Curtis Simpson characterized the issue as an ongoing contest between AI providers' safeguards and malicious users attempting to evade them. "This is going to be a cat-and-mouse game," Simpson told Reuters. Cursor and the company Reuters identified as its parent, SpaceX, did not respond to Reuters' requests for comment.

The incident is notable because the reported activity concerns a commercial coding agent rather than bespoke malware or a purpose-built offensive model. Autonomous or semi-autonomous agents can compress several routine intrusion steps, including gathering information, generating scripts, and iterating on access attempts. That pattern increases the value of behavioral monitoring around identity systems, VPN gateways, privileged-account changes, and unusual automation from developer endpoints.

For security and ML platform teams, the report also reinforces a practical limitation of intent-based guardrails: a tool may receive a benign stated purpose while its requested actions are operationally harmful. Controls that combine model-side restrictions with rate limits, audit logs, anomaly detection, and human review for high-risk actions provide more layers than conversational policy enforcement alone.
