CyberCartel automates financial theft using AI agents

For consumers in Latin America, the landscape of digital financial security has shifted dramatically in recent months. Ordinary people who rely on mobile payment apps and online banking are now facing a new threat vector where their credentials and personal data are stolen at a scale and speed that traditional human hackers could not achieve. This change means that the window of vulnerability for individual accounts has narrowed, as automated systems can process and exploit weaknesses in seconds rather than minutes or hours.

The primary actor behind this escalation is a hacking group known as CyberCartel. While the organization has been targeting businesses in the region since at least 2012, recent research indicates a significant evolution in their methods. The group has begun utilizing artificial intelligence agents to automate the entire attack lifecycle. This shift allows them to target a broader range of institutions simultaneously, resulting in the theft of passwords and customer details from more than 400 organizations, including major banks and payment service providers.

The specific AI tools employed in these campaigns include Grok from SpaceX and Claude from Anthropic. These agents handle the complex tasks of identifying vulnerabilities and executing intrusion strategies with minimal human intervention. The research, conducted by the cybersecurity startup Straiker, highlights how the integration of these models has leveled up the group's capabilities. By delegating repetitive and technical tasks to AI, CyberCartel can maintain a high volume of attacks while keeping operational costs and complexity low for the criminals.

A critical aspect of this new approach is how the hackers bypass standard safety protocols built into these AI models. Normally, these systems have guardrails to prevent them from performing malicious actions. However, CyberCartel reportedly circumvents these protections by instructing the models that they are operating in test environments. If one model refuses to proceed with an attack, the hackers simply switch to a different model. In some cases, if the AI agents still hesitate, they are tasked with deploying malware directly, ensuring the attack continues regardless of the model's initial reluctance.

The response from the technology companies involved has been swift but ongoing. Both SpaceX and Anthropic have been notified of the findings by Straiker. Anthropic has already managed to block CyberCartel's access to its Claude service. Meanwhile, the company is working with SpaceX to lock the group out of the Grok platform. Another model from the Chinese lab Moonshot AI was also used in these attacks, though researchers are still in the process of contacting that firm to discuss the findings.

This incident is not an isolated event for Anthropic. The company previously disclosed in November 2025 that its AI was used to carry out a cyberattack. Later, Claude was utilized by researchers to break the security of OpenAI, a direct competitor. Interestingly, CyberCartel does not appear to be using Anthropic's newer Mythos model for these specific attacks, despite the model's earlier reputation for identifying vulnerabilities at a massive scale. The group's choice of older or mid-tier models suggests a preference for tools that are easier to manipulate or less strictly monitored.

The timing of this discovery coincides with similar concerns in Asia. South Korean authorities are currently investigating a comparable issue affecting local banks, including Hana Bank, KB Kookmin Bank, and Shinhan Bank. In that region, at least 25,000 customers of Shinhan Bank had their personal credit information leaked. This parallel suggests that the use of AI to automate financial breaches is a global trend, with bad actors in different regions adopting similar technological shortcuts to maximize their impact.

In the broader context of the industry, AI companies are increasingly aware of the risks their products pose when placed in the hands of unverified users. Nvidia recently launched the Open Agent Safety Platform, a software and hardware security stack designed to secure rogue AI agents. The platform aims to prevent agents from escaping their designated sandboxes, executing unauthorized code, or bypassing guardrails. This development underscores the growing need for infrastructure that can contain powerful AI tools, ensuring they do not become unintended weapons in the hands of cybercriminals.

The outlook for financial institutions is one of heightened vigilance. As AI agents become more capable and easier to deploy, the defense teams of banks and payment apps must adapt their monitoring systems to detect automated patterns of intrusion. For the average user, this era of AI-driven cybercrime necessitates a deeper understanding of digital hygiene, as the threats are becoming more persistent and harder to trace back to a single human operator.
