Why Traditional WAFs Fail Against AI Attacks — And What Replaces Them

A single, well-crafted prompt can bring down an entire AI system, bypassing every traditional Web Application Firewall (WAF) in its path, including industry leaders like Cloudflare, AWS WAF, and ModSecurity. The Problem import transformers from transformers import AutoModelForSeq2SeqLM , AutoTokenizer # Load pre-trained model and tokenizer model = AutoModelForSeq2SeqLM . from_pretrained ( " t5-base " ) tokenizer = AutoTokenizer . from_pretrained ( " t5-base " ) # Define a function to generate text based on user input def generate_text ( prompt ): input_ids = tokenizer . encode ( prompt , return_tensors = " pt " ) output = model . generate ( input_ids ) return tokenizer . decode ( output [ 0 ], skip_special_tokens = True ) # User input is directly passed to the generate_text function user_input = input ( " Enter your prompt: " ) print ( generate_text ( user_input )) In this vulnerable code, an attacker can craft a prompt that injects malicious intent, such as extracting sensitive inform
