Prompt Injection — The #1 Risk for AI Applications
Direct and indirect prompt injection attacks, defense strategies, and input sanitization for AI features
If you're building features powered by LLMs — chatbots, content generators, AI assistants, summarizers — prompt injection is your biggest security risk. Not hypothetically. Right now, today, in production applications.
Prompt injection is to AI applications what SQL injection was to web applications in 2005. It's the attack that every AI-powered application is vulnerable to until the developer explicitly addresses it. And just like SQL injection, the consequences range from embarrassing to catastrophic.
What Is Prompt Injection?
Prompt injection occurs when an attacker crafts input that causes an LLM to deviate from its intended behavior. Instead of treating the attacker's input as data, the model treats it as instructions.
There are two types: direct and indirect.
