    Quantum Route Redirect phishing campaign targeting Microsoft 365 users

    Initial Disclosure

    KnowBe4 identified Quantum Route Redirect (QRR) as a phishing automation platform stealing Microsoft 365 credentials through credential-harvesting pages hosted on around 1,000 domains, often on parked or compromised domains. The lure emails impersonate DocuSign requests, payment notifications, missed voicemails, or QR codes, and the kit uses a human-vs-bot filtering layer that sends automated scanners to benign sites while routing real visitors to URLs that follow the `/([\w\d-]+\.){2}[\w]{,3}\/quantum.php/` pattern. Observed activity spans 90 countries, with 76% of attacks directed at users in the U.S., and defenders are advised to deploy robust URL filtering and account monitoring for compromise.
