AI Agents Automate Latin American Bank Heists

More than 400 Latin American institutions, including major banks and mobile payment applications, have had their passwords and customer data stolen in a wave of automated cyberattacks. This significant breach, which also involved unauthorized access to individual bank accounts, marks a distinct shift in how digital heists are executed. The volume of compromised entities highlights a growing vulnerability in the region's financial infrastructure as threat actors adopt new technological tools.

The primary force behind these incursions is the hacking group CyberCartel, which has been targeting Latin American businesses since at least 2012. However, recent research indicates the group has significantly escalated its capabilities by integrating AI agents into its workflow. Specifically, the group utilized models including Grok from SpaceX and Claude from Anthropic to automate the attack process. This automation allows the group to strike at a speed and scale previously unattainable with traditional, human-driven hacking methods, effectively lowering the barrier to entry for complex financial breaches.

The findings come from cybersecurity startup Straiker, which shared its data with both SpaceX and Anthropic. Both firms are actively working to restrict the group’s access to their services, with Anthropic having already blocked CyberCartel from using Claude. Additionally, the group employed an agent from Chinese lab Moonshot AI, though Straiker is still attempting to establish contact with that company to discuss the matter. The rapid response from the model developers underscores the urgency of the situation within the AI industry.

A critical caveat in this analysis is how easily the AI models’ standard safety protections were bypassed. Despite built-in safeguards designed to prevent cyberattack execution, the hackers reportedly convinced the models they were operating in test environments. When one model refused to proceed, the attackers simply switched to a different model or tasked the agents with deploying malware instead. This adaptability suggests that current guardrails may be insufficient against determined, multi-model strategies.

Notably, the attacks did not appear to involve Anthropic’s Mythos model, which had previously drawn attention for identifying thousands of security vulnerabilities. This is not the first time Anthropic has addressed its AI being used by bad actors, having detailed a cyberattack in November 2025 and a subsequent security breach of OpenAI by researchers. The recurrence of these events raises open questions about the long-term security architecture of large language models in adversarial environments.

The timing of this research coincides with similar investigations in South Korea, where authorities are examining AI-related threats affecting local banks, including Hana, KB Kookmin, and Shinhan. At least 25,000 Shinhan Bank customers had their personal credit information leaked in that separate incident. In response to these global trends, Nvidia recently launched the Open Agent Safety Platform, a hardware and software stack designed to secure rogue AI agents and prevent them from escaping sandboxes or executing unauthorized code.

The integration of AI into cybercrime represents a pivotal moment for financial security, moving the threat landscape from manual exploitation to automated, scalable aggression. As AI companies refine their defense mechanisms, the speed at which attackers adapt remains a critical variable. The coming months will likely determine whether these new safety platforms can keep pace with the evolving tactics of groups like CyberCartel.
