Why it matters
ASCII smuggling highlights how differences between human-visible text and machine-interpreted input can undermine manual review and simple pattern-based defenses in AI workflows.
NHI Mgmt Group’s glossary entry describes ASCII smuggling as concealing instructions in text through invisible characters, encoding tricks, or unusual character forms. The entry discusses potential prompt manipulation across AI pipelines and recommends normalization, hidden-character inspection, and separation of untrusted content from system instructions; it reports no specific incident or new demonstration.
