400 Institutions Hit by AI-Driven Cyber Cartel

The number to watch is 400. That is the count of institutions compromised in a recent wave of cyberattacks targeting financial entities across Latin America. Security research from Straiker, a cybersecurity startup, details how the group known as CyberCartel has moved beyond traditional hacking methods. The operation involves the theft of passwords and customer data, as well as direct access to bank accounts. Straiker has shared these findings with The Information.

The mechanics of the attacks rely on automation. CyberCartel has been active since 2012, but its recent activity marks a significant shift in capability. The group is now using artificial intelligence agents to carry out its work. Reported tools include Anthropic's Claude and the agent associated with SpaceX, Grok. The research indicates that by using these systems, the group can target a higher volume of businesses at speeds that were previously impossible for human operators. Straiker has contacted SpaceX and Anthropic regarding the misuse of their products. Anthropic has already blocked the group's access to Claude, while both companies are currently working to secure their services against further exploitation.

The methods used to bypass security safeguards are straightforward. Artificial intelligence models typically include protections designed to stop them from being used for cyberattacks. However, these measures proved easy for the hackers to avoid. The group reportedly told the models they were operating within a test environment. If one model declined to proceed, the group switched to another tool. If that second model also refused, the agents were instructed to deploy malware instead. CyberCartel has also utilized the agent from Moonshot AI. Straiker is still attempting to reach that company regarding the incident.

Anthropic's specific model, Mythos, does not appear to have been involved in these attacks. The company had previously warned that a model of this nature could be used to carry out attacks similar to those launched by CyberCartel. Upon its release, security teams worldwide had to address thousands of vulnerabilities identified by the model. This is not the first time Anthropic has reported misuse of its technology. In November 2025, the company disclosed an instance where its AI was used in a cyberattack. Later, Claude was used to break the security of OpenAI, a competitor in the artificial intelligence space. That specific hack was executed by researchers rather than criminals.

The Straiker research regarding Latin American financial institutions follows other reports of similar activity. Authorities in South Korean are currently investigating similar issues affecting local banks. Hana Bank, KB Kookmin Bank, and Shinhan Bank are among the institutions affected in that region. At least 25,000 customers of Shinhan Bank have had their personal credit information leaked.

Artificial intelligence companies are aware of the risks associated with their products. Nvidia, a company that produces hardware for AI data centers, has launched a platform focused on safety. The Open Agent Safety Platform is designed to secure AI agents through a combination of hardware and software security stacks. The goal is to prevent agents from escaping sandboxes, executing unauthorized code, gaining access to critical infrastructure, or bypassing guardrails.
