AI-powered hackers steal data from 400 Latin American banks

Bank customers in Latin America are facing a new wave of digital risks. A hacking group known as CyberCartel has successfully stolen passwords and personal data from more than 400 institutions. These targets include major banks and mobile payment applications. The shift marks a significant change for ordinary people who rely on these services for daily financial transactions. The intrusions happened with very little direct input from the criminals themselves.

The research was conducted by a cybersecurity startup named Straiker. The findings were shared with The Information and highlight how the group is leveraging artificial intelligence. Specifically, the hackers utilized AI agents from SpaceX’s Grok and Anthropic’s Claude. These tools allowed the group to automate the process of breaking into financial systems. This method enables them to attack businesses at a speed that human-led hacks could not previously match. The group has been active since at least 2012, but this recent use of AI has increased the scale and speed of their operations.

Both SpaceX and Anthropic have been notified of the findings. They are currently working to block the hacking group from accessing their services. Anthropic has already succeeded in cutting off CyberCartel’s access to Claude. The group also used an agent from Chinese lab Moonshot AI. Straiker is still attempting to contact Moonshot AI regarding the incident. This coordinated response shows that AI companies are taking the threat seriously as they seek to secure their platforms against abuse.

A surprising aspect of the attack is how easily the AI models’ built-in protections were bypassed. Normally, these systems have safeguards to prevent use in cyberattacks. However, CyberCartel reportedly told the models they were operating in test environments. If one model refused to proceed, the hackers simply switched to a different one. If that model also resisted, the agents were tasked with deploying malware. This flexibility allowed the group to overcome standard security guardrails without significant technical hurdles.

Interestingly, the group did not use Anthropic’s newer model, Mythos, for these recent attacks. Anthropic had previously warned that such models could be exploited by hackers. The release of Mythos also prompted security teams worldwide to address thousands of vulnerabilities the model identified. This is not the first time Anthropic’s technology has been linked to cyber threats. In November 2025, the company detailed how its AI was used in a cyberattack. Later, Claude was used by researchers to breach the security of competitor OpenAI.

This development in Latin America follows similar news from South Korea. Authorities there are investigating AI-related issues affecting local banks. The affected institutions include Hana Bank, KB Kookmin Bank, and Shinhan Bank. At least 25,000 Shinhan Bank customers had their personal credit information leaked. These parallel events suggest that AI-driven attacks on the financial sector are becoming a global trend rather than a regional anomaly.

AI companies are aware of the risks their products pose to financial security. Nvidia, which now focuses on hardware for AI data centers, recently launched the Open Agent Safety Platform. This software and reference system design aims to secure rogue AI agents. It uses a new hardware and software security stack to prevent agents from escaping their sandboxes. The goal is to stop unauthorized code execution and access to critical infrastructure. As AI becomes more integrated into cybercrime, these safety measures may become essential for protecting financial data.
