Microsoft researchers recently uncovered a large phishing campaign that used "๐๐๐๐๐ ๐๐ฆ๐ฎ๐ ๐ ๐ฅ๐ข๐ง๐ ", an AI-era evasion technique, to hide parts of words using invisible Unicode characters and bypass email security checks. What looks normal to users can appear completely different to security filters.

โข Signature hits jumped from around 21,000 messages to over 1.3 million messages in a single day.
โข The campaign peaked at more than 2.3 million phishing emails and remained active for nearly three months.
โข Around 96% of the detected volume was linked to finance-themed phishing campaigns.

Invisible Unicode characters popularized for hiding instructions from AI models are now being used to obfuscate words before email filters parse them.
