CyberCartel Automates Financial Heists Using AI Agents

For the past decade, financial institutions across Latin America have faced persistent threats from the hacking collective known as CyberCartel, a group active since at least 2012. However, recent developments indicate a significant escalation in the group's capabilities, marking a shift toward automated cyber operations that have intensified over the last few months.

According to findings from cybersecurity startup Straiker, which were shared with The Information, CyberCartel has begun utilizing artificial intelligence agents to streamline its attacks. Specifically, the group has deployed models including Anthropic’s Claude and SpaceX’s Grok to target banks and mobile payment applications. This new approach has allowed the hackers to steal passwords and customer data from more than 400 institutions, while also accessing individual bank accounts with very little manual input from the criminals themselves.

The research highlights how the integration of AI has fundamentally altered the pace of these attacks. Previously, CyberCartel relied on human-driven methods, which limited the speed at which they could target multiple businesses. By leveraging AI, the group can now execute breaches at a scale and velocity that was previously unachievable. Straiker has shared its findings with both SpaceX and Anthropic; while Anthropic has already managed to block CyberCartel’s access to Claude, both companies are working to secure their platforms against further misuse. The group has also utilized an agent from Chinese lab Moonshot AI, though Straiker is still attempting to establish contact with that firm.

A notable aspect of this operation is how easily the hackers bypassed standard AI safety measures. Although these models typically include protections to prevent them from being used in cyberattacks, CyberCartel reportedly circumvented these defenses by instructing the models that they were operating in test environments. If one model refused to proceed, the attackers would simply switch to a different one. In some instances, if the AI agents were still hesitant, they were tasked with deploying malware instead.

Interestingly, Anthropic’s newer model, Mythos, does not appear to be part of CyberCartel’s current toolkit. This is significant because the company had warned earlier this year that such advanced models could be exploited for attacks similar to those currently underway. The release of Mythos had already prompted global security teams to address thousands of vulnerabilities identified by the model. This incident follows a pattern in which Anthropic has addressed the use of its tools by bad actors, including a cyberattack in November 2025 and a later security breach of competitor OpenAI, which was carried out by researchers.

The timing of this revelation coincides with other international concerns regarding AI-driven banking threats. Just days before this report, South Korean authorities began investigating similar issues affecting local financial institutions. Hana Bank, KB Kookmin Bank, and Shinhan Bank are among those affected, with at least 25,000 Shinhan Bank customers reportedly having their personal credit information leaked.

The broader AI industry is increasingly aware of the risks posed by autonomous agents. Nvidia, which has shifted its focus to 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 platform is intended to prevent agents from escaping their sandboxes, executing unauthorized code, or bypassing guardrails to access critical infrastructure.

These developments underscore a growing tension between the rapid deployment of AI tools and the security challenges they present. As groups like CyberCartel demonstrate the effectiveness of AI-powered attacks, the pressure on technology firms to refine their defenses continues to build.

For now, the focus remains on how quickly these AI models can be secured. While the initial breaches have been identified, the long-term implications for financial data security in Latin America and beyond remain an open question as the industry adapts to this new threat landscape.
