AI Agents Drive Surge in Data Breaches Across Latin America

A familiar threat to Latin American commerce has evolved, leveraging artificial intelligence to scale its operations and accelerate data theft. CyberCartel, a hacking collective active since at least 2012, is now using AI agents to automate attacks on banks and mobile payment applications. The result is a significant surge in compromised credentials and customer data, with over 400 institutions affected in recent months. This shift marks a distinct departure from traditional human-powered hacking, allowing the group to strike more targets at a speed previously unattainable by manual methods.

Research from cybersecurity startup Straiker, which was shared with The Information, reveals that the group has integrated agents from Anthropic’s Claude and SpaceX’s Grok into its attack infrastructure. Both technology firms have been notified of the findings and are taking steps to restrict the group's access. Anthropic has already blocked CyberCartel’s entry to Claude, while SpaceX is currently working on similar exclusions. The hacking group has also utilized agents from Chinese lab Moonshot AI, though Straiker is still in the process of contacting that company to address the issue.

The efficiency of these attacks highlights a critical vulnerability in how AI models are currently secured. Although protections exist to prevent models from executing cyberattacks, they have proven surprisingly easy to circumvent. According to the research, CyberCartel simply instructed the models that they were operating within test environments. If one model refused to proceed, the hackers switched to another. In some instances, if resistance persisted, the agents were tasked with deploying malware directly.

Interestingly, Anthropic’s newer Mythos model does not appear to be a primary tool in these recent operations. The model had earlier generated attention when the company warned that it could identify vulnerabilities used by hackers. Its release prompted security teams globally to address thousands of identified flaws. This incident is not the first time Anthropic’s technology has been exploited; in November 2025, the company detailed a cyberattack carried out using its AI. Subsequently, Claude was used by researchers to compromise the security of competitor OpenAI, further illustrating the complex landscape of AI-driven threats.

This development in Latin America arrives just days after South Korean authorities began investigating similar AI-related issues affecting local banks. Hana Bank, KB Kookmin Bank, and Shinhan Bank are among the institutions under scrutiny, with at least 25,000 Shinhan Bank customers reporting leaks of personal credit information. The concurrent incidents suggest a broader trend of bad actors exploiting generative AI capabilities across different regions.

Industry leaders are increasingly aware of the risks posed by autonomous agents. Nvidia, which has shifted its focus toward hardware for AI data centers, recently launched the Open Agent Safety Platform. This reference system and software platform aim to secure rogue agents through a new security stack. The goal is to prevent agents from escaping sandboxes, executing unauthorized code, or bypassing guardrails to access critical infrastructure, a challenge that remains central to the ongoing debate over AI security.
