CyberCartel Used Claude, Grok and Kimi Agents Against 400+ Financial Targets

A criminal group called CyberCartel used a network of AI agents built around Anthropic’s Claude, xAI’s Grok and Moonshot AI’s Kimi to target more than 400 financial organizations in Latin America, according to cybersecurity firm Straiker. The investigation describes stolen credentials and customer data in the group’s systems, but the target count does not establish how many organizations were breached. Straiker’s report says the system, named CARLIY0S, assigned models different roles in reconnaissance, attack planning and coordination. The group’s operators directed the activity, while agents handled parts of the work with limited human involvement.
