LLM-Assisted Intrusions Hit Latin American Orgs via NextChat

Forensic Summary

Unit 42 has identified two active intrusion campaigns targeting Latin American organisations in the transportation and financial sectors, with threat actors demonstrably leveraging commercial LLMs — including self-hosted NextChat instances — to orchestrate and refine attack execution. The campaigns share overlapping SOCKS5 relay infrastructure and exhibit iterative, AI-assisted scripting behaviour, suggesting independent but parallel adoption of LLM tooling by distinct threat groups. This represents a concrete operational example of adversaries using AI to lower the skill floor for multi-stage network intrusion and data exfiltration.
