Scammers Use Hidden Text to Bypass AI-Powered Email Security Filters

Scammers are embedding hidden, invisible text within phishing emails to evade detection by AI-powered email security filters. The technique aims to manipulate machine learning models used in spam and phishing detection, increasing the likelihood that malicious emails reach user inboxes. Security researchers at Sublime Security identified the method, which exploits gaps in how AI systems process and classify email content. No specific dates, affected organizations beyond Adidas (used as an example in related scams), or technical indicators like CVE IDs were disclosed. The impact includes a higher success rate for phishing campaigns due to reduced filtering effectiveness.
