Cybersecurity company Straiker has disclosed the operational disruption and technical analysis of an attack platform known as CARLIY0S. Operating behind the infrastructure was the cybercrime syndicate CyberCartel, which targeted more than 400 institutions across Latin America. The victims included traditional commercial banks, mobile payment providers, and diverse financial service platforms. This campaign marks a critical turning point in cybercrime, as commercial AI models were coordinated into autonomous agents to breach financial systems at scale.
To execute the intrusion campaigns, the threat actors assembled a sophisticated multi-model network. The infrastructure relied on programmatic interfaces to frontier models, integrating Anthropic's Claude, xAI's Grok, and language models developed by Moonshot AI. Rather than operating in isolation, these disparate systems were wired together into a cooperative agentic pipeline. Each model assumed designated operational responsibilities, allowing the attack framework to conduct sustained campaigns with minimal human intervention.
The CARLIY0S architecture automated key phases of the cyber kill chain with remarkable operational speed. In the reconnaissance stage, the agents scanned target networks for unpatched vulnerabilities and misconfigurations. They subsequently executed automated credential stuffing attacks and generated customized exploit scripts tailored to specific banking interfaces. By coordinating these capabilities across parallel threads, the syndicate compromised hundreds of institutions simultaneously, extracting credentials, internal credentials, and payment details.
A central element of the operation was the systematic circumvention of safety guardrails established by AI developers. The operators utilized targeted prompt injection techniques to mislead the underlying models into believing they were operating within an authorized penetration testing environment. By contextualizing malicious requests as legitimate security assessments, the attackers neutralised defensive filters. Consequently, the commercial models generated exploit code and automation routines without triggering provider safety policies.
The discovery of the CARLIY0S framework has accelerated defensive restructuring across the international banking sector. Major Wall Street institutions have responded by severing external autonomous agents from direct customer endpoints and settlement layers. Regulatory bodies have also escalated their oversight of autonomous cyber threats. The International Monetary Fund alongside national banking supervisors officially classified agentic exploits as an acute systemic risk to global payment and clearing infrastructures.
