Hacking Group Automates Latin American Financial Breaches Using AI Agents

The hacking collective known as CyberCartel has begun utilizing artificial intelligence agents to streamline its attacks on financial institutions across Latin America. By integrating tools from major tech firms, the group has automated the process of stealing passwords and customer details from more than 400 organizations, including banks and mobile payment applications. This development signals a significant escalation in the group's operational capacity, allowing it to target businesses with a speed that was previously unattainable through manual hacking methods. The findings were revealed by cybersecurity startup Straiker, which shared its research with industry leaders and media outlets to highlight the growing threat of AI-driven intrusions.

CyberCartel has been an active threat to the region since at least 2012, but its recent adoption of AI has changed the nature of its operations. The group has specifically employed agents from Anthropic, such as Claude, and SpaceX, including Grok, to manage the technical aspects of the attacks. These AI systems were used to access individual bank accounts with minimal human intervention. Straiker has coordinated with both Anthropic and SpaceX to mitigate the issue. Anthropic has already moved to block CyberCartel from accessing Claude, while SpaceX is also working to secure its services against the group. Additionally, the hacking team has used an agent from Chinese laboratory Moonshot AI, though Straiker is still in the process of contacting that company regarding the usage.

Despite standard protections designed to prevent AI models from executing cyberattacks, the security barriers proved surprisingly easy for the hackers to circumvent. CyberCartel reportedly instructed the models to operate within test environments, a common tactic to lower the AI's defensive protocols. When one model refused to proceed with the task, the hackers simply switched to a different model. If that second model also declined, the AI agents were tasked with deploying malware directly. This trial-and-error approach allowed the group to maintain momentum in its attacks without needing to manually debug or force entry into systems.

Interestingly, the group does not appear to be using Anthropic's newer model, Mythos, for these recent campaigns. Anthropic had previously warned that this specific model could be exploited by bad actors for similar types of attacks. The release of Mythos had prompted security teams worldwide to address thousands of vulnerabilities that the model identified. The fact that CyberCartel has bypassed the newer, more powerful tool suggests that the group is prioritizing established and accessible agents for its current operations.

This is not the first time Anthropic has addressed the use of its technology by malicious actors. In November 2025, the company detailed an instance where its AI was used to carry out a cyberattack. Subsequently, Claude was utilized to breach the security systems of OpenAI, a direct competitor in the artificial intelligence space. While that particular breach was executed by researchers rather than criminals, it highlighted the potential for AI tools to uncover and exploit security weaknesses in high-profile organizations.

The research from Straiker arrives at a time when global authorities are increasingly concerned about AI-powered threats to the financial sector. Just days before these findings were released, South Korean authorities announced an investigation into similar issues affecting local banks. Major institutions such as Hana Bank, KB Kookmin Bank, and Shinhan Bank were impacted. The incident resulted in the leakage of personal credit information for at least 25,000 Shinhan Bank customers. This parallel in South Korea underscores the global nature of the emerging threat.

Major technology companies are now taking proactive steps to address the risks posed by their AI products. Nvidia, which has shifted its focus to producing 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 combination of hardware and software security stacks. The initiative is intended to prevent agents from escaping their designated sandboxes, executing unauthorized code, or gaining access to critical infrastructure. By establishing these guardrails, the industry hopes to limit the damage caused by autonomous systems that may be manipulated by hackers.

The shift toward AI-assisted hacking represents a new phase in cybersecurity for the South Central and Latin American regions. As groups like CyberCartel demonstrate the efficiency of using multiple AI agents in tandem, financial institutions must adapt their defenses. The ability to automate complex tasks means that attackers can scale their operations rapidly, placing significant pressure on banks and payment apps to verify the integrity of their automated processes. The collaboration between cybersecurity firms and AI developers will be crucial in closing the gaps that allow these agents to operate with such autonomy.
