Tracking BigBear 2.0 Evilginx2 Phishing Campaign

In June 2026, researchers uncovered BigBear 2.0, a rebranded Evilginx2-based phishing-as-a-service framework targeting Microsoft 365 credentials globally. The operation, managed by operator 'General Boss', deployed 42 VPS nodes primarily hosted on Vultr infrastructure, utilizing the 'offy' phishlet configuration. The platform employed adversary-in-the-middle techniques with geo-matched residential proxy pools across 69 countries, real-time Telegram exfiltration, and automated cookie replay to bypass MFA. The campaign exfiltrated 5,137 credential records including 474 complete MFA-bypassed authentications, 1,032 plaintext passwords, and 4,148 session cookies, affecting 3,331 unique victim IPs across 40+ countries. The multi-user PhaaS panel was leased to at least five identified affiliate operators. Custom JavaScript injections disabled FIDO2/WebAuthn MFA while residential proxies bypassed anti-bot detection, enabling persistent access to compromised Microsoft 365 environments.
