As you may have realised already, Artificial intelligence has become our digital assistant, our creative partner, and increasingly, our business collaborator. We ask AI to summarize documents, write emails, analyze data, and even make recommendations that influence important decisions.

But there’s a fundamental security vulnerability lurking in how these AI systems work—one that’s been ranked as the number one risk for AI applications by the Open Worldwide Application Security Project (OWASP) in 2025. I was researching on this topic and decided to share my findings in this post.
So, this vulnerability is known as prompt injection, and understanding it isn’t just for security professionals anymore. If you use AI tools in your work or personal life, you need to know how attackers can manipulate these systems to do things they were never intended to do.
