An industrialized ecosystem of infostealer malware (Lumma Stealer, Raccoon Stealer) and Phishing-as-a-Service platforms (Tycoon 2FA, Acreed) is enabling attackers to steal authenticated session tokens from user endpoints and directly hijack cloud, SaaS, email, and financial portal sessions — bypassing TOTP and push-based MFA entirely. This is not a patchable vulnerability; it exploits design-level session management gaps and endpoint credential exposure. The required response is architectural: device-bound sessions, phishing-resistant MFA, and endpoint telemetry on browser credential store access.
