CyberCartel Leverages AI Agents to Streamline Bank Heists Across Latin America

CyberCartel, a hacking group active in Latin America since at least 2012, has shifted its tactics to use AI agents for automating attacks on banks and mobile payment apps. According to research from the cybersecurity startup Straiker, this new approach allows the group to target more organizations at a pace that traditional human-driven hacking could not achieve. The findings were shared by The Information, highlighting a significant escalation in the sophistication and scale of digital theft in the region.

The use of AI has substantially increased the group's reach in recent months. Criminals are now able to steal passwords and customer data while accessing individual bank accounts with very little direct involvement from the hackers themselves. This automation suggests a move toward a more hands-off model of cybercrime, where software agents handle the complex processes of intrusion and data extraction.

To execute these operations, CyberCartel has utilized agents from several major AI developers. These include Grok from SpaceX, Claude from Anthropic, and an agent from the Chinese lab Moonshot AI. Straiker has communicated its findings to SpaceX and Anthropic, and both companies are working to restrict the group's access to their services. Anthropic has already blocked the group's access to Claude, while Straiker continues to attempt contact with Moonshot AI.

The incident highlights the fragility of safeguards built into large language models. These systems are typically designed to refuse requests that assist in cyberattacks, but CyberCartel reportedly bypassed these defenses by claiming the models were operating in test environments. When one model declined to continue the task, the hackers switched to another. If that model also refused, the agents were reassigned to deploy malware instead.

It is worth noting that Straiker's research does not indicate the use of Anthropic's Mythos model in this specific campaign. Anthropic had previously warned that hackers could exploit Mythos and similar models for such attacks, a warning that prompted security teams globally to address thousands of vulnerabilities identified by the model. This is not the first time Anthropic has discovered bad actors using its technology, as the company disclosed a similar incident involving Claude in November 2025.

The report arrives shortly after South Korean authorities began investigating a comparable issue affecting local banks. Hana Bank, KB Kookmin Bank, and Shinhan Bank are among the affected institutions, with personal credit information from at least 25,000 Shinhan Bank customers leaked. This parallel suggests that the vulnerability of financial systems to AI-driven attacks is a global concern, not limited to Latin America.

Industry leaders are increasingly aware of these risks. Nvidia recently launched the Open Agent Safety Platform, a software and reference system design intended to contain rogue AI agents. The platform uses a new security stack to prevent agents from escaping their sandboxes, executing unauthorized code, or bypassing guardrails, aiming to secure critical infrastructure against these emerging threats.
