{"success":true,"data":{"id":"zero-font-random-word-salting","label":"ZeroFont NLP evasion — 2+ invisible spans stuffed with random natural-language noise words to dilute AI classifier signal","description":"HTML body contains 2+ invisible spans/divs stuffed with random natural-language noise words — the ZeroFont text-dilution technique that breaks NLP-based phishing classifiers by adding \"benign\" filler text invisible to the recipient but consumed by content classifiers. Distinct from css-hidden-text-salting (which aggregates 3+ concealment techniques); this fires on the single-technique ZeroFont pattern with 2+ noise blocks and excludes URLs/email-addresses (those are scored elsewhere). Documented by Inky/TechTarget, CheckPoint Email Security, BleepingComputer, SANS ISC Diary 30248 (2025), and MDPI 2025.","tier":"danger","category":"body","isThin":false}}
