Once popular for attacking AI, ASCII smuggling is embraced by spammers
A clever technique used to hide malicious prompts in attacks on AI agents has been adopted by spammers to evade filters on email platforms that are designed to flag unwanted messages used in mass campaigns. The technique is broadly known as ASCII smuggling. It gained attention two years ago as a means of making a class of AI attack known as prompt injections more stealthy. Malicious instructions embedded in emails or other untrusted content to be processed by an LLM aren’t written in ordinary te
ASCII smuggling uses invisible Unicode characters that computers can read but humans cannot see. Originally used to hide malicious instructions in attacks on AI language models, spammers have now adopted the technique to evade email filters by obscuring keywords commonly flagged in spam messages. The invisible characters disrupt how spam detection systems tokenize and analyze text, causing filters to miss trigger words while the message appears normal to human readers. This technique is more effective against machine learning and natural language processing-based filters than traditional obfuscation methods like zero-width spaces.
