New paper argues both regex and fine-tuned classifiers share critical failure modes for detecting prompt injection. Regex misses paraphrased attacks, classifiers get bypassed at >50% success rates by adaptive adversaries. The paper proposes seven detection techniques from fields outside NLP. If you're building agent pipelines processing untrusted input, pattern matching alone won't save you.
