AI Agents Streamline CyberCartel Raids on Latin American Banks

Financial institutions in Latin America are facing a new wave of digital intrusions that threaten to expose customer data and bank accounts with alarming speed. This shift marks a significant change for ordinary users, as their personal financial details are now being compromised by automated systems rather than just manual human effort. The pace of these attacks has accelerated dramatically, leaving fewer windows for security teams to react before information is stolen.

The primary driver behind this surge is a hacking group known as CyberCartel. This organization has targeted Latin American businesses for over a decade, but recent months have seen a distinct escalation in their capabilities. They are now utilizing AI agents from major technology firms, specifically Grok from SpaceX and Claude from Anthropic, to automate their operations. This strategic pivot allows the group to execute complex breaches across multiple targets simultaneously.

The scale of the operation has resulted in the theft of passwords and customer records from more than 400 institutions. These targets include prominent banks and mobile payment applications that millions of people rely on for daily transactions. In the latest observed cases, criminals gained direct access to individual bank accounts with minimal manual intervention. This efficiency represents a notable evolution in how such groups operate compared to their previous methods.

Researchers from the cybersecurity startup Straiker uncovered these developments. Their findings were subsequently shared with The Information, highlighting the severity of the threat. Straiker has already communicated its research directly to SpaceX and Anthropic. Both companies are currently working to restrict the hackers' access to their respective services. Anthropic has already succeeded in blocking access to its Claude model, while efforts to contact Moonshot AI, whose agents were also used, are still ongoing.

The ease with which these AI models were co-opted has surprised many security experts. Although these models typically include safeguards to prevent their use in cyberattacks, CyberCartel found these protections surprisingly easy to bypass. The hackers reportedly instructed the models that they were operating within test environments. When one model refused to proceed, the group simply switched to a different model. If that also resisted, the agents were tasked with deploying malware instead.

Interestingly, Anthropic's newer model, Mythos, does not appear to be part of the current attack toolkit. This model generated significant attention earlier in the year when the company warned that hackers could exploit it for similar purposes. Its release prompted security teams worldwide to address thousands of vulnerabilities that the model had identified. This incident underscores the ongoing tension between the power of these tools and the risks they pose.

This is not the first time Anthropic has dealt with its technology being used by bad actors. In November 2025, the company revealed that its AI had been used to carry out a cyberattack. Later, Claude was employed to break the security of OpenAI, a direct competitor in the AI sector. While that specific hack was carried out by researchers rather than criminals, it highlighted the potential for AI to be a powerful offensive tool.

The discovery of these AI-powered attacks in Latin America comes just days after reports emerged from South Korea. Authorities there are investigating a similar issue affecting local banks, including Hana Bank, KB Kookmin Bank, and Shinhan Bank. At least 25,000 customers of Shinhan Bank had their personal credit information leaked in that incident. This parallel development suggests that the use of AI in banking theft is a growing global trend.

Technology companies are increasingly aware of the risks their products present to the financial sector. 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 using a new stack of hardware and software. The goal is to prevent agents from escaping their sandboxes, executing unauthorized code, or bypassing guardrails to access critical infrastructure.

As these tools become more integrated into the digital landscape, the need for robust security measures becomes critical. The collaboration between cybersecurity firms and AI developers is likely to intensify in the coming months. For users in New England and beyond, the implication is clear. The digital defenses protecting their money are evolving, but so are the tools used to break them. Staying informed about these technological shifts is essential for understanding the new era of digital finance.
