A large-scale phishing campaign used invisible Unicode characters from the deprecated Unicode Tags block to obfuscate keywords related to loans and financing, bypassing email filters that rely on contiguous ASCII string matching. The campaign sent between 1 million and 2.37 million messages daily at its peak in early 2026, primarily targeting recipients with fraudulent loan offers. The messages were routed through the legitimate marketing platform ActiveCampaign, leveraging its reputation to evade detection. There is no software vulnerability or patch associated with this technique; it exploits differences in how email clients and filters process Unicode text. Mitigation requires enhanced email filtering that inspects raw Unicode content and flags or removes invisible characters to detect obfuscated phishing keywords.
