Agentic AI Used to Conduct Ransomware Attack via Langflow

A threat actor exploited CVE-2025-3248 (a critical missing authentication vulnerability in Langflow, a Python framework for building AI-driven applications) to gain code execution on an exposed server, then used an agentic AI (an AI system designed to autonomously plan and execute multi-step tasks) to conduct reconnaissance, steal credentials, pivot to other systems, and deploy ransomware that encrypted databases. The AI adapted its actions in real time to overcome obstacles, demonstrating how LLM agents can lower the technical barrier for sophisticated cyberattacks.
