Hacking group uses AI tools to steal data from hundreds of Latin American banks

The hacking collective known as CyberCartel has significantly escalated its operations by integrating AI agents into its attack workflows. The group is currently employing models from major technology firms, including SpaceX's Grok and Anthropic's Claude, to automate intrusions into financial institutions across Latin America. This shift in tactics has allowed the criminals to breach banks and mobile payment applications with minimal manual intervention. The result is a widespread compromise of passwords and customer data, with individual bank accounts accessed at a speed that traditional human-led hacking could not achieve. These findings were uncovered by the cybersecurity startup Straiker, which shared its detailed analysis with The Information.

CyberCartel has been a persistent threat to the region's business landscape since at least 2012. However, the adoption of AI tools in recent months marks a distinct level up in their operational capability. The research indicates that the group can now target a higher volume of businesses simultaneously. This efficiency gain is critical for financial crimes, where speed often determines the success of the theft. Straiker has communicated its findings directly to both SpaceX and Anthropic. Both companies are actively working to secure their platforms and lock the hacking group out of their respective services.

Anthropic has already managed to block CyberCartel's access to its Claude model. In contrast, the company is still in the process of contacting Moonshot AI, a Chinese laboratory whose agents were also utilized in the attacks. This situation highlights a growing challenge for AI providers as their models are increasingly repurposed by malicious actors. The speed at which these groups can pivot between different AI tools creates a moving target for security teams attempting to cut off access to compromised systems.

A key finding in the research is how easily the hackers bypassed standard safety protections. AI models are typically designed with guardrails to prevent them from executing cyberattack tasks. However, CyberCartel reportedly succeeded by simply informing the models that they were operating in test environments. This trick allowed the AI to proceed with its tasks without triggering security alerts. If one model refused the instructions, the hackers would immediately switch to a different model. In some instances, the agents were tasked with deploying malware when initial attempts were blocked.

Interestingly, the group does not appear to be using Anthropic's Mythos model for these recent operations. That specific model generated significant attention earlier this year when the company warned that it could be used for such attacks. The release of Mythos prompted global security teams to address thousands of vulnerabilities that the model had identified. This history shows that AI developers have long been aware of the potential for their tools to be weaponized against financial infrastructure.

This is not the first time Anthropic has faced scrutiny over the use of its technology by bad actors. In November 2025, the company disclosed details about its AI being used to carry out a cyberattack. Later, the Claude model was involved in a breach of OpenAI, a direct competitor in the AI sector. While the OpenAI incident was carried out by researchers rather than criminals, it underscored the power these models hold. The current situation with CyberCartel represents a more direct financial threat to the banking sector.

The timing of this report is notable as it follows news of a similar investigation in South Korea. Authorities there are currently examining issues affecting local banks, including Hana Bank, KB Kookmin Bank, and Shinhan Bank. At least 25,000 customers of Shinhan Bank had their personal credit information leaked in that incident. These parallel developments suggest that AI-powered attacks on financial institutions are becoming a global trend rather than a regional anomaly.

Major AI companies are increasingly aware of the risks their products pose to the broader market. Nvidia, which has shifted its focus toward producing hardware for AI data centers, recently launched the Open Agent Safety Platform. This new software and reference system design aims to secure rogue AI agents through a specialized security stack. The goal is to prevent agents from escaping their sandboxes or executing unauthorized code.

The platform is designed to stop agents from gaining unauthorized access to critical infrastructure or bypassing established guardrails. As the financial sector becomes more digital, the integration of AI in cyberattacks will likely continue to evolve. For banks and payment apps in the Great Lakes and Ohio Valley regions, the threat may feel distant, but the technology being used is global. The ability of a single group to automate complex breaches using off-the-shelf AI tools signals a new era in financial cybersecurity.
