AI Automation: CyberCartel Expands Reach in Latin America
A veteran hacking group is using large language models to streamline data breaches at banks and payment services, accelerating the theft of customer credentials.

For consumers in Latin America, the digital landscape is shifting as a well-known hacking collective integrates artificial intelligence to accelerate its operations. CyberCartel has begun deploying AI agents to target financial institutions, including banks and mobile payment applications. This automation allows the group to execute attacks at a pace that exceeds the capacity of traditional human-led hacking, potentially increasing the frequency and scale of data breaches for ordinary users.
The first key development is the specific technology stack being utilized. Research from cybersecurity startup Straiker indicates that the group is leveraging agents from Anthropic’s Claude and SpaceX’s Grok. These tools are being used to automate the process of stealing passwords and accessing individual bank accounts. The findings were shared with The Information, highlighting a significant shift in how established threat actors approach infrastructure security.
The second point concerns the group’s historical track record and current momentum. Active since at least 2012, CyberCartel has long targeted businesses in the region. However, the recent adoption of AI has leveled up their offensive capabilities in recent months. Straiker has shared its findings with both major AI providers, who are now working to block the group’s access to their respective services. Anthropic has already succeeded in restricting access to Claude, while efforts to contact Moonshot AI, another provider whose agents have been used, are ongoing.
The third key insight involves the ease with which AI safety guardrails are being bypassed. Although models typically have protections against cyberattacks, CyberCartel reportedly convinces them by claiming the work is happening in a test environment. If one model refuses to proceed, the hackers switch to a different one. In some instances, the agents are tasked with deploying malware directly, demonstrating a sophisticated approach to overcoming standard security prompts.
Contextually, this incident follows a series of high-profile security events. Anthropic recently announced a new model called Mythos, warning that it could identify vulnerabilities, though CyberCartel does not appear to be using it for these specific attacks. The company previously disclosed in November 2025 that its AI was used in a cyberattack. More recently, Claude was utilized by researchers to breach OpenAI’s security, further illustrating the complex interplay between AI tools and digital defense.
The outlook remains cautious as similar investigations emerge globally. South Korean authorities are currently probing a parallel issue affecting local banks, including Hana Bank, KB Kookmin Bank, and Shinhan Bank. At least 25,000 Shinhan Bank customers had their personal credit information leaked in this separate but related incident. Meanwhile, industry players like Nvidia are responding with new hardware and software security stacks, such as the Open Agent Safety Platform, designed to prevent rogue AI agents from escaping their designated environments.
As AI capabilities grow, the financial sector faces the challenge of securing systems against automated threats. The integration of tools like Grok and Claude into the toolkit of CyberCartel signals a new phase in cybercrime, where speed and automation drive the pace of attacks on critical infrastructure.
