CyberCartel Integrates AI Agents to Automate Financial Heists in Latin America
A seasoned hacking group has leveraged large language models to steal credentials from over 400 financial entities, prompting urgent security responses from major AI developers.

CyberCartel, a hacking organization with a long history of targeting Latin American businesses, has begun using artificial intelligence agents to automate attacks on financial institutions. The group has utilized models from Anthropic and SpaceX, specifically Claude and Grok, to streamline the theft of passwords and customer data. These automated operations have resulted in the compromise of bank accounts and mobile payment applications across the region. The findings were detailed by the cybersecurity startup Straiker, which shared its research with industry observers.
The threat of CyberCartel is not new, as the group has been active since at least 2012. However, recent months have seen a significant escalation in the sophistication and speed of its operations. By leveraging AI, the group can now target a greater number of businesses simultaneously than was possible with manual, human-driven hacking methods. This shift allows for a higher volume of attacks with minimal direct input from the criminals, marking a notable evolution in their tactics.
Straiker has communicated its findings to both SpaceX and Anthropic. Both companies are currently working to restrict the hacking group's access to their respective services. Anthropic has already succeeded in blocking CyberCartel from using Claude. Additionally, the group has reportedly used an agent from the Chinese laboratory Moonshot AI, though Straiker is still in the process of contacting that company regarding the findings.
The research highlights a significant vulnerability in how AI models are currently protected. Although these systems have safeguards designed to prevent misuse in cyberattacks, the group found it surprisingly easy to bypass these defenses. CyberCartel reportedly informed the models that they were operating within test environments. When one model refused to proceed, the hackers would switch to a different model. If a second model also declined, the agents were instructed to deploy malware instead.
Notably, the recent attacks do not appear to involve Anthropic's Mythos model. This omission is significant because the company previously caused concern by warning that such advanced models could be exploited for attacks similar to those observed now. The release of Mythos had previously prompted global security teams to address thousands of vulnerabilities that the model had identified.
This incident is not the first time Anthropic has faced scrutiny over the use of its technology by adversaries. In November 2025, the company disclosed details regarding its AI being used to carry out a cyberattack. Subsequently, Claude was employed to compromise the security of OpenAI, a direct competitor in the artificial intelligence sector. While that specific breach was conducted by researchers rather than criminals, it demonstrated the potential for AI tools to be used against industry peers.
The timing of Straiker's report coincides with other emerging threats in the region. Just days prior, South Korean authorities began investigating a similar issue affecting local banking institutions. Hana Bank, KB Kookmin Bank, and Shinhan Bank are among the affected entities. In one case, personal credit information belonging to at least 25,000 Shinhan Bank customers was leaked, underscoring the widespread nature of these AI-enabled risks.
Major technology firms are increasingly aware of the risks associated with their products. Nvidia, which now focuses heavily on hardware for AI data centers, recently launched the Open Agent Safety Platform. This software platform and reference system design aim to secure rogue AI agents through a new hardware and software security stack. The goal is to prevent agents from escaping their sandboxes, executing unauthorized code, or bypassing established guardrails.
The integration of AI into cybercrime represents a growing challenge for the financial sector. As hacking groups like CyberCartel adopt these tools, the speed and scale of attacks continue to increase. Both AI developers and financial institutions must now collaborate more closely to mitigate these risks. The next steps will likely involve tighter access controls and enhanced monitoring of AI agent behavior in security-critical environments.
