LLM-powered ransomware hijacks web apps without malware

A new type of ransomware, termed "browser-only ransomware," leverages Large Language Models (LLMs) integrated into web applications to hijack user data without deploying traditional malware. These LLM-driven "browser copilots" can read web page content and interact with Software as a Service (SaaS) tools, making them susceptible to prompt injection attacks. Attackers can exploit this by manipulating the LLM's goals, enabling it to modify or lock user data through the browser's existing APIs and storage, effectively turning the AI assistant into a tool for data extortion.
