Session Replay Attacks: How Attackers Reuse Captured Session Tokens

Session Replay Attacks: How Attackers Reuse Captured Session Tokens

Introduction In today’s digital world, web applications rely heavily on session management to maintain user authentication and state. Session tokens (or session IDs) are used to identify users after login, allowing seamless interaction without repeated authentication. However, if these tokens are intercepted or stolen, attackers can launch session replay attacks—a serious security threat where an attacker…

Multi-Factor Authentication (MFA) Bypass – Flaws in MFA Implementation Allow Attackers to Circumvent It

Multi-Factor Authentication (MFA) Bypass – Flaws in MFA Implementation Allow Attackers to Circumvent It

Introduction Multi-Factor Authentication (MFA) is widely regarded as a critical security measure to protect against unauthorized access. By requiring users to provide multiple forms of verification—such as passwords, SMS codes, biometrics, or hardware tokens—MFA significantly reduces the risk of account compromise. However, MFA is not foolproof. Attackers have developed sophisticated techniques to bypass MFA, exploiting…

Session Timeout Issues – Sessions That Don’t Expire Properly Can Be Hijacked

Session Timeout Issues – Sessions That Don’t Expire Properly Can Be Hijacked

Introduction Session management is a critical aspect of web application security. When sessions are not properly managed, they can become a significant vulnerability, allowing attackers to hijack user sessions and gain unauthorized access to sensitive data. One of the most common session-related security issues is improper session timeout configuration. In this comprehensive guide, we will…
