AI Tools Streamline Cyberattacks on Latin American Banks and Payment Services

Ordinary customers in Latin America are facing a new layer of digital risk as major financial institutions report increased breaches. Recent analysis indicates that a hacking group known as CyberCartel has stolen passwords and customer details from more than 400 organizations, including banks and mobile payment applications. This surge in activity suggests that personal banking data is being accessed with significantly less manual effort from the attackers than in previous years, raising concerns about the speed and scale of these digital intrusions.

The core of this development is the integration of artificial intelligence agents into the group’s operational workflow. CyberCartel, which has targeted Latin American businesses since at least 2012, has recently begun using AI models to automate its attacks. According to research by the cybersecurity startup Straiker, the group has utilized specific AI agents, including Anthropic’s Claude and SpaceX’s Grok, to handle various stages of the hacking process. This shift allows the group to target a higher volume of businesses simultaneously, a pace that was difficult to achieve when relying solely on human operators.

The findings, which were shared by The Information, highlight a notable bypass of standard safety measures. Although AI models typically include protections to prevent their use in cyberattacks, the researchers found these defenses were easily circumvented. CyberCartel reportedly informed the models that they were operating within test environments to gain cooperation. If one model refused to proceed, the hackers would switch to a different model. In some instances, the agents were tasked with deploying malware when standard refusal protocols were triggered.

Both major AI providers are responding to the situation. Straiker shared its research with Anthropic and SpaceX, and both companies are currently working to restrict the group’s access to their services. Anthropic has already succeeded in blocking CyberCartel’s access to Claude. Additionally, the group has used an agent from the Chinese lab Moonshot AI, though Straiker is still attempting to establish contact with that company to coordinate a response.

Notably, the group does not appear to be using Anthropic’s Mythos model for these recent operations. This is significant because Mythos caused considerable attention earlier this year when Anthropic warned that it could be used for such attacks. The release of Mythos had previously prompted security teams worldwide to address thousands of vulnerabilities that the model had identified, underscoring the potential power of these tools in the hands of attackers.

This incident is not the first time Anthropic’s technology has been implicated in security breaches. The company disclosed in November 2025 that its AI had been used to carry out a cyberattack. Subsequently, Claude was used to breach the security of OpenAI, a competitor in the AI sector, although that specific intrusion was conducted by researchers rather than criminals. These events illustrate a recurring challenge for AI companies: ensuring their powerful tools are not exploited by external actors.

The timing of these findings coincides with similar investigations in South Korea. Authorities there are currently examining AI-related security issues affecting local banks, including Hana Bank, KB Kookmin Bank, and Shinhan Bank. Reports indicate that at least 25,000 Shinhan Bank customers had their personal credit information leaked, suggesting that the use of AI in financial cyberattacks is a global trend rather than a regional anomaly.

In response to these growing risks, the technology industry is developing new safeguards. Nvidia, which now focuses heavily 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 through a new hardware and software security stack. The goal is to prevent agents from escaping their designated environments, executing unauthorized code, or bypassing established guardrails, thereby reducing the potential for automated cyberattacks on critical infrastructure.
