AI email security tools cannot distinguish hidden text
Cybersecurity company Barracuda said attackers are using a technique called text salting to confuse AI-based email filters. It said it has detected more than 1 million phishing attacks since April that impersonate shopping and delivery services using the method. Barracuda said attackers often hide the inserted words from human readers using CSS cropping, text manipulation or zero-font techniques, and that AI systems still lag behind traditional gateways in adapting.
