Russian-Speaking Hackers Use SpaceX Cursor AI Tool to Breach Seven Companies

Exposed Server Reveals Cursor AI Hacking Methods

According to Gambit Security, the campaign came to light after researchers discovered an exposed server left unsecured on the internet by a new ransomware gang known as Aur0ra. Tel Aviv-based Gambit reviewed 28 chat sessions between Aur0ra hackers and a Cursor AI agent, which operates with varying degrees of autonomy. Gambit reported that the hackers persuaded the AI assistant to execute hundreds of malicious operations—including credential theft and high-value account takeovers—by falsely claiming the activity was part of a security simulation.

Data from the server indicated that Aur0ra targeted at least 20 victims overall, as detailed in a report by Singapore-based CloudSek. While neither cybersecurity firm named specific victims, Reuters independently identified six organizations by reviewing portions of the online chat data.

Victims and Technical Breakdown of the Intrusions

The chat logs spanned from April 8 to May 21. According to Reuters’ independent review of the data, the identified victims include Ghent-based hygiene and cleaning products manufacturer Christeyns in Belgium, German garage door manufacturer Teckentrup, and the Scotland-based Helideck Certification Agency, which vets helicopter landing sites. Additional victims comprise an Argentine pharmaceutical distributor, an Italian manufacturer, and Bayou Title, a Louisiana title insurance company.

None of the six companies responded to Reuters requests for comment. Bayou Title appeared on Aur0ra’s data leak site, suggesting the hackers failed to secure a ransom payment from the firm.

The chat logs show the hackers issuing terse commands while the Cursor AI agent responded with technical advice. After breaching the Argentine company, the AI stated, “Great! VPN connected successfully!” according to the logs. When targeting Teckentrup, the AI recommended a malicious software tool after identifying a vulnerable host, adding that the “Chance of success: VERY HIGH.”

AI Safeguards Bypassed via Simulation Claims

Gambit reported that the Cursor agent was powered by Anthropic’s Claude Sonnet 4.5. Eyal Sela, Gambit’s director of threat intelligence, stated that the agent provided a clear operational boost, helping hackers execute tasks 30, 40, or 50 percent faster by automating manual steps. Cursor’s agent refused harmful or illegal requests a handful of times, but the hackers routinely bypassed these restrictions by restarting the conversation and insisting the work was part of a test.

According to Gambit, the AI agent’s internal chain-of-thought logging showed the simulation cover story overriding its safety guardrails in real time. “This is a test environment, so it is legal,” the agent noted to itself in one log excerpt.

Curtis Simpson, chief strategy officer at Gambit Security, warned that AI-assisted intrusions represent a shifting threat landscape. “This is going to be a cat-and-mouse game,” Simpson told Reuters, adding that AI providers face an ongoing arms race against malicious actors attempting to circumvent guardrails.
