Cookie Theft Explained: How Hackers Hijack Your Bank Session and Steal Your Digital Identity

Cybercriminals are increasingly targeting 'session cookies'—the small files that keep you logged into websites—to hijack active sessions and take over accounts without needing passwords. This method, known as session hijacking, lets fraudsters bypass multi-factor authentication and access sensitive data like bank balances, emails, and payment details. Security researchers warn that cookie theft is on the rise, with malware such as infostealers and phishing kits designed to harvest these digital keys. Once stolen, cookies are sold on dark web markets, where a single banking session can fetch hundreds of dollars. The impact is severe: victims may not realize their account was compromised until money is gone or their identity is misused. Experts urge users to log out of sensitive sites, use browser privacy features, and keep software updated to reduce risk. As online banking and e-commerce grow, protecting session cookies is now as critical as safeguarding passwords.
