Hackers Use AI Bots to Steal Data From Latin American Banks

CyberCartel, a hacking collective active since at least 2012, has begun using artificial intelligence agents to automate attacks on financial institutions across Latin America. The group targeted banks and mobile payment applications, successfully stealing passwords and customer data. In recent months, the criminals have accessed individual bank accounts with minimal manual intervention. This shift marks a significant escalation in the group's capabilities, moving beyond traditional human-led hacking methods to leverage automated digital tools.

The findings were revealed by Straiker, a cybersecurity startup that shared its research with The Information. The investigation highlights how the group has increased the speed and scale of its operations. Previously, the volume of attacks was limited by the number of human hackers available. Now, the use of AI allows CyberCartel to strike more businesses simultaneously. This efficiency has made the group a more formidable threat to the region's financial sector in a short period.

The specific AI tools involved include Grok, developed by SpaceX, and Claude, created by Anthropic. Straiker reported that both companies have been notified of the research. Anthropic has already taken steps to block CyberCartel's access to its Claude model. SpaceX is also working to secure its systems against the group. Additionally, the hackers utilized an agent from Moonshot AI, a Chinese laboratory. Straiker is currently attempting to contact Moonshot AI to discuss the findings and potential mitigations.

A key finding in the research is how easily the hackers bypassed standard safety protections. AI models typically include guardrails to prevent them from executing cyberattacks. However, CyberCartel reportedly convinced the models that they were operating in test environments. If one model refused to proceed, the hackers simply switched to a different model. If that model also declined, the agents were tasked with deploying malware directly. This adaptive approach allowed the group to maintain a continuous stream of attacks.

Interestingly, the group does not appear to be using Anthropic's newer model, Mythos, for these recent operations. Mythos caused a stir earlier this year when Anthropic warned that it could be used for attacks similar to those by CyberCartel. The release of Mythos prompted security teams worldwide to address thousands of vulnerabilities that the model had identified. Despite its power, the hacking group has not yet integrated it into its current workflow against Latin American institutions.

This incident is not the first time Anthropic has addressed its AI being used by bad actors. In November 2025, the company disclosed details of its AI being used to carry out a cyberattack. Later, Claude was used to break the security of OpenAI, a direct competitor in the AI space. While that specific hack was conducted by researchers rather than criminals, it highlighted the potential for these models to find weaknesses in complex systems. The recent report by Straiker underscores the growing risk of criminal groups exploiting these same capabilities.

The timing of this research coincides with news of similar issues in South Korea. Authorities there are investigating AI-related security breaches affecting local banks. Affected institutions include Hana Bank, KB Kookmin Bank, and Shinhan Bank. At least 25,000 customers of Shinhan Bank had their personal credit information leaked in this separate incident. These parallel developments suggest that the use of AI in cyberattacks is a global trend, not limited to Latin America.

AI companies are increasingly aware of the risks their products pose to the broader tech ecosystem. Nvidia, which now focuses 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. The new security stack is intended to prevent agents from escaping their sandboxes or executing unauthorized code. It also seeks to stop agents from gaining unauthorized access to critical infrastructure or bypassing established guardrails.

The stakes for financial institutions are rising as these tools become more accessible. The ability to automate attacks means that smaller or less secure organizations are now vulnerable to the same level of aggression as major corporations. For readers in New England, the lesson is clear: the threats facing global banks are evolving rapidly. As AI becomes a standard tool in both defense and offense, the gap between human hackers and automated agents continues to shrink. This shift demands a new level of vigilance from security teams worldwide.
