UK Cyber Agency Warns of Persistent Vulnerability in AI Language Models
The UK's top cyber agency has issued a warning regarding a persistent flaw in large language model (LLM) AI tools, which could allow malicious actors to hijack these models. This flaw, known as prompt injection, enables attackers to manipulate AI models by sending malicious requests disguised as instructions. The National Cyber Security Centre (NCSC) highlighted that this vulnerability is deeply embedded in the architecture of LLMs, making it impossible to completely eliminate. The issue arises because these models do not differentiate between trusted and untrusted content, treating all prompts as instructions. This vulnerability has been a concern since the launch of ChatGPT in 2022, with security researchers identifying it as a significant security risk.
