Cyber attackers are getting smarter, and businesses relying on Multi-Factor Authentication (MFA) may not be as safe as they think. Session Hijacking 2.0 is the latest method hackers are using to bypass MFA and gain access to cloud-based applications. In this article, we’ll dive into how Session Hijacking 2.0 works, why it poses a serious risk to your business, and what steps you can take to protect yourself from this new form of attack.
The New Attack That Bypasses MFA and Steals Your Data
How Session Hijacking 2.0 Works: The Silent Attack
Session Hijacking 2.0 is an evolution of a familiar cyber threat. Traditionally, hackers would intercept traffic on unsecured networks, but today’s attackers are targeting the session cookies and tokens that are used in cloud-based apps. By stealing these tokens, hackers can hijack an active session from a different device, bypassing MFA completely. With tokens valid for up to 30 days, attackers have a wide window of opportunity to exploit compromised sessions without the need for passwords.

Think your business is safe because you’ve implemented Multi-Factor Authentication (MFA)? Think again. Cybercriminals are using a new technique—Session Hijacking 2.0—to bypass MFA and infiltrate cloud applications. Learn how this silent threat works and what you can do to protect your organization before it’s too late.
The Rise of Phishing Attacks with a New Twist
Phishing attacks are a common vector for Session Hijacking 2.0. Using Adversary-in-the-Middle (AitM) and Browser-in-the-Middle (BitM) tactics, attackers trick users into revealing their session tokens during login. AitM intercepts all authentication material, while BitM gives hackers remote control of the victim’s browser, allowing them to bypass MFA and take control of sessions. These phishing methods are more sophisticated than ever, making them harder to detect and stop.
Infostealers: The Hidden Threat in Session Hijacking
Another key element of Session Hijacking 2.0 is the use of infostealers. These malicious programs extract session cookies from a victim’s browser and allow hackers to import them into their own devices. Once an attacker has these cookies, they can bypass MFA and access sensitive applications without triggering alarms. Infostealers often spread through malicious ads, infected downloads, or compromised websites, making them a widespread and dangerous tool for hackers.
Why Session Hijacking 2.0 is a Major Risk to Your Business
Session Hijacking 2.0 is particularly dangerous for businesses using cloud-based services like Microsoft 365 or Salesforce. Once hackers gain access to a session, they can infiltrate not only the targeted app but also all interconnected services tied to that user’s identity. This can lead to massive data breaches, operational disruptions, and financial losses. The worst part? The user may never even know their session was hijacked.
Protecting Your Business from Session Hijacking 2.0
To protect against this emerging threat, businesses need a multi-layered security approach. Endpoint Detection and Response (EDR) tools are essential for detecting and stopping malware like info-stealers. Training employees on how to spot phishing attacks is equally critical, as human error often opens the door for session hijacking. Implementing strong access controls at the application level, along with browser-based monitoring tools that flag unusual session activity, can also add an extra layer of defense.
