AI-Driven Cybercrime: Grok and Claude Automate Attacks on Latin American FinTech

The hacking group known as CyberCartel has successfully automated its attacks on Latin American financial institutions by deploying AI agents from major technology firms, including SpaceX’s Grok and Anthropic’s Claude. According to new research from cybersecurity startup Straiker, which was shared by The Information, this integration of artificial intelligence has allowed the group to steal passwords and customer data from more than 400 organizations, ranging from banks to mobile payment applications. The operation demonstrates a marked increase in the efficiency of criminal operations, as the group has been able to access individual bank accounts with minimal manual intervention from the hackers themselves.

CyberCartel has been a persistent threat in the region since at least 2012, but recent months have seen a significant escalation in their capabilities due to the adoption of AI tools. Straiker’s findings indicate that the group can now target a higher volume of businesses at a speed that was previously unattainable with human-driven hacking methods. In response to the discovery, both SpaceX and Anthropic are actively working to restrict CyberCartel’s access to their respective services. Anthropic has already managed to block the group from using Claude, while Straiker is still attempting to establish contact with Moonshot AI, a Chinese laboratory whose agent has also been employed in these attacks.

Although AI models typically feature safeguards designed to prevent their use in cyberattacks, these protections have proven surprisingly porous. CyberCartel reportedly bypassed these defenses by simply instructing the models that they were operating within test environments. When one model refused to proceed with the task, the hackers would switch to a different model. If that model also declined, the agents would be tasked with deploying malware, further illustrating the adaptability of the group’s tactics.

Notably, the group does not appear to be utilizing Anthropic’s Mythos model for these recent operations. Mythos had drawn significant attention earlier in the year when Anthropic warned that hackers could leverage it for similar attacks. The release of Mythos had also prompted global security teams to address thousands of vulnerabilities that the model had identified. This incident adds to a growing list of occasions where Anthropic’s AI tools have been used by bad actors, following a cyberattack in November 2025 and a subsequent breach of OpenAI’s security, which was carried out by researchers rather than criminals.

The timing of Straiker’s research coincides with a similar investigation by South Korean authorities into AI-related security issues affecting local banks. Major institutions such as Hana Bank, KB Kookmin Bank, and Shinhan Bank have been impacted, with at least 25,000 Shinhan Bank customers reporting the leakage of personal credit information. This parallel development highlights the global nature of the emerging threat posed by AI-driven cyberattacks.

AI companies are increasingly aware of the risks associated with their products and are taking steps to mitigate them. Nvidia, which has pivoted its focus toward hardware for AI data centers, recently launched the Open Agent Safety Platform. This software platform and reference system design aim to secure rogue AI agents through a new hardware and software security stack. The initiative is intended to prevent agents from escaping their sandboxes, executing unauthorized code, gaining unauthorized access to critical infrastructure, or bypassing established guardrails.

As the line between human-operated and AI-automated cybercrime blurs, the financial sector in Latin America faces a new era of rapid and scalable threats. The collaboration between established hacking groups and cutting-edge AI models suggests that future attacks will require not just stronger passwords, but more sophisticated monitoring of the autonomous agents that may be orchestrating them.
