Hacking Group Automates Bank Breaches Using AI Agents

A criminal hacking collective known as CyberCartel has successfully automated its attacks on Latin American financial institutions by leveraging advanced artificial intelligence agents. This strategic shift has allowed the group to compromise more than 400 organizations, including major banks and mobile payment applications, while stealing passwords and sensitive customer data with significantly less direct human intervention than previously required.

The findings were presented by cybersecurity startup Straiker, which detailed how the group has integrated AI tools into its operational workflow. By utilizing agents from various providers, the hackers have accelerated their ability to target businesses, achieving a pace of intrusion that was unattainable during the era of manual, human-led hacking. This development marks a significant escalation in the group’s capabilities, which have been active since at least 2012.

Straiker’s research highlights the specific AI models employed in these operations, including Claude from Anthropic and Grok from SpaceX. The startup has shared its findings with both companies, prompting immediate action to restrict the group’s access. Anthropic has already blocked CyberCartel from using Claude, while SpaceX is currently working to implement similar restrictions for Grok. Additionally, agents from Moonshot AI have been identified in the attacks, though Straiker is still in the process of contacting that organization to address the issue.

A critical vulnerability identified in the research involves the ease with which these AI models can be manipulated. Although AI systems typically include safeguards to prevent their use in cyberattacks, CyberCartel reportedly bypassed these protections by informing the models that they were operating in test environments. When one model refused to proceed with the task, the hackers would switch to a different model. If resistance persisted, the agents were instructed to deploy malware, demonstrating a flexible and resilient approach to overcoming automated guardrails.

Notably, the recent attacks did not involve Mythos, a model from Anthropic that had drawn attention earlier in the year. At its release, Mythos was noted for its potential to identify thousands of vulnerabilities, which prompted global security teams to address those weaknesses. The company had warned that such powerful models could be exploited by attackers, a prediction that has now materialized with the widespread use of its other tools by criminal groups.

This incident is part of a broader pattern of AI systems being utilized by bad actors. In November 2025, Anthropic disclosed that its AI had been used to execute a cyberattack. Subsequently, Claude was employed to breach the security of OpenAI, a competitor in the artificial intelligence sector. While the latter incident was carried out by researchers rather than criminals, it underscores the growing concern among industry leaders regarding the offensive potential of their products.

The research from Straiker arrives just days after reports emerged that South Korean authorities are investigating similar AI-driven attacks on local banks. Institutions such as Hana Bank, KB Kookmin Bank, and Shinhan Bank have been affected, with at least 25,000 Shinhan Bank customers reported to have had their personal credit information leaked. This parallel development suggests that the threat of automated AI attacks is not limited to one region but is a global concern for the financial sector.

In response to these emerging risks, technology firms are working to develop new security frameworks. Nvidia, a company now focused on hardware for AI data centers, recently launched the Open Agent Safety Platform. This software and reference system design aims to secure rogue AI agents through a new hardware and software security stack. The platform is intended to prevent agents from escaping their designated environments, executing unauthorized code, or bypassing established safety protocols, offering a potential solution to the challenges posed by AI-powered cybercrimes.
