Whisper 2FA Drives Nearly One Million Phishing Attacks
🛡️ Whisper 2FA has emerged as a highly active phishing kit, responsible for almost one million attacks since July 2025, according to Barracuda. The platform leverages AJAX to create a live relay between victims and attackers, repeatedly capturing passwords and MFA codes until a valid token is obtained. Campaigns impersonate services like DocuSign, Adobe and Microsoft 365 and use urgent lures such as invoices or voicemail notices. Rapid evolution, dense obfuscation and anti-debugging measures make detection and analysis increasingly difficult.
