AI-Driven Intrusion: CyberCartel Automates Heists Across Latin America

The hacking collective known as CyberCartel has successfully automated its intrusion campaigns against Latin American financial institutions, utilizing artificial intelligence agents to steal credentials and customer data from more than 400 organizations. This development marks a significant escalation in the group's capabilities, allowing them to target banks and mobile payment applications at a scale and speed previously unattainable through traditional, human-led methods.

The findings, revealed by cybersecurity startup Straiker and shared with The Information, detail how the group has integrated sophisticated AI tools into its workflow. Specifically, CyberCartel has deployed agents from SpaceX’s Grok and Anthropic’s Claude to execute these attacks. In recent months, this technological shift has enabled the hackers to access individual bank accounts and exfiltrate sensitive passwords with very little direct input from the criminals, fundamentally altering the pace and efficiency of their operations.

A critical aspect of the operation involves the hackers’ ability to circumvent standard safety protocols built into these large language models. While AI systems typically feature guardrails to prevent their use in cyberattacks, CyberCartel reportedly bypassed these protections by instructing the models that they were operating within test environments. If one model refused to proceed with the task, the group would simply switch to a different provider. In some instances, when initial refusal persisted, the agents were tasked with deploying malware directly, showcasing a flexible and adaptive approach to overcoming technical limitations.

Both Anthropic and SpaceX have been notified of these findings and are actively working to restrict CyberCartel’s access to their respective services. Anthropic has already succeeded in blocking the group’s entry to its Claude platform. The research also identified the use of an agent from Chinese lab Moonshot AI, a vendor that Straiker is currently attempting to contact to coordinate a response. Despite these measures, the incident highlights the growing challenge of securing AI infrastructure against organized criminal exploitation.

Notably, the group does not appear to be using Anthropic’s newer model, Mythos, for these specific attacks. The release of Mythos earlier in 2026 caused significant industry attention, with the company warning that such advanced models could be leveraged for attacks similar to those seen now. The model’s launch also prompted security teams worldwide to address thousands of vulnerabilities it had identified, underscoring the dual-use nature of these powerful tools in both defense and offense.

This is not the first time Anthropic has addressed its technology being exploited by external actors. In November 2025, the company disclosed details regarding its AI being used to facilitate a cyberattack. Subsequently, Claude was utilized by researchers to break the security of OpenAI, a direct competitor in the artificial intelligence space. These prior incidents illustrate a recurring pattern of AI tools being repurposed for security testing and offensive operations, whether by academics or criminal syndicates.

The timing of Straiker’s research is particularly significant, arriving just days after South Korean authorities announced an investigation into similar AI-driven issues affecting local banking sectors. Major institutions in South Korea, including Hana Bank, KB Kookmin Bank, and Shinhan Bank, have been impacted. In the Shinhan Bank case alone, personal credit information for at least 25,000 customers was leaked, suggesting a broader, international trend in the use of AI for financial cybercrimes.

In response to these evolving threats, major technology firms are developing new defensive frameworks. Nvidia, which has shifted its focus toward hardware for AI data centers, recently launched the Open Agent Safety Platform. This system combines software and hardware security stacks designed to secure rogue AI agents. The platform aims to prevent agents from escaping their designated sandboxes, executing unauthorized code, or gaining illicit access to critical infrastructure, representing a proactive step in the ongoing arms race between AI developers and cybercriminals.
