The AI App Nobody Audited (And What Happened Next)

Short summary

A fintech startup deployed an AI assistant without considering prompt injection attacks—a critical vulnerability where attackers craft inputs to override system instructions. Three attack types threaten production AI: jailbreaks strip guardrails, prompt injection redirects the model, and prompt leakage extracts system prompts. Mitigate via AWS Bedrock Guardrails with input tagging, defense-in-depth practices, and regular adversarial testing.

• •Prompt injection is a language-based attack where crafted user inputs override AI system instructions
• •Three attack vectors: jailbreaks (strip guardrails), prompt injection (task redirection), prompt leakage (extract system prompts)
• •Mitigate using AWS Bedrock Guardrails with input tagging, defense-in-depth validation, and adversarial testing
