What is Prompt Injection in Cybersecurity?
An attack against LLM-powered applications where malicious input overrides the system's intended instructions. Direct prompt injection embeds commands in user input, while indirect injection hides instructions in external data the model retrieves. Successful attacks can bypass safety filters, exfiltrate data, or make the model perform unauthorized actions.
Why Prompt Injection Matters for Your Cybersecurity Career
Prompt injection is the SQL injection of the AI era. Penetration testers now include LLM testing in their engagements. Security engineers building AI-powered features must implement input validation and output filtering to defend against this attack class. Understanding this vulnerability is becoming a baseline expectation.
