The rapid adoption of Large Language Models (LLMs) such as ChatGPT, Claude, and Gemini has revolutionised enterprise operations across industries—from customer support and legal drafting to cybersecurity automation and product innovation. However, this surge in usage has opened new frontiers for cyber threats. Among the most pressing is LLM01:2025 Prompt Injection, the first and arguably the most dangerous vulnerability in OWASP’s Top 10 for LLMs.
Prompt injection attacks manipulate LLMs into executing unintended behaviours, bypassing safety protocols, generating harmful content, or leaking sensitive data—all of which hold serious business, regulatory, and reputational implications.
