Hackers Bypass MFA to Hijack Email Accounts Using Stolen Browser Cookies

by Justin Erickson

A recent FBI warning alerts users of Gmail, Outlook, AOL, and Yahoo to a rise in account takeovers despite multi-factor authentication (MFA). Hackers are using stolen browser cookies to bypass MFA protections, enabling unauthorized access to email accounts. Once inside, attackers can steal sensitive information, reset passwords, and even execute further phishing attacks. Users are urged to regularly clear browser cookies, monitor account activity, and remain cautious with unfamiliar login prompts.
