Token Theft Attacks

Summary

Token Theft Attacks involve the unauthorized acquisition of authentication tokens, such as session tokens or JSON Web Tokens (JWT), to impersonate legitimate users and gain unauthorized access to applications or services. These attacks exploit vulnerabilities in token storage, transmission, or management within web and mobile applications.

Key Characteristics

• Target authentication tokens used for session management or API access.
• Commonly exploit insecure storage mechanisms like local storage or cookies.
• May leverage cross-site scripting (XSS), man-in-the-middle (MITM), or social engineering techniques.
• Allow attackers to bypass authentication and authorization controls.
• Often difficult to detect as stolen tokens mimic legitimate user activity.

Defensive Controls

• Implement secure token storage using HttpOnly and Secure cookie flags.
• Use short-lived tokens with frequent expiration and refresh mechanisms.
• Employ strong input validation and Content Security Policy (CSP) to prevent XSS.
• Enforce Transport Layer Security (TLS) to protect tokens in transit.
• Monitor and analyze token usage patterns to detect anomalies.
• Implement multi-factor authentication to reduce reliance on tokens alone.
