While cybersecurity focuses on password strength and multi-factor authentication, the threat of session token theft, or “side jacking,” is overlooked. said Davit Asatryan, Product Director at Spin.AI. Compromised tokens allow cybercriminals to bypass password security, highlighting the need for comprehensive security measures that include secure session management.
In the world of cybersecurity, numerous defenses exist to prevent a wide range of digital threats. While most people are familiar with the importance of strong passwords and the increasing adoption of multi-factor authentication (MFA), there are less obvious but equally pressing concerns. It is also known as “session token theft.”side jack.These tokens are essential for maintaining user state during a web session, but they can be a prime target for cybercriminals and, if compromised, can provide unauthorized access to user accounts. Even the most stringent password measures can be circumvented. This highlights the need for comprehensive security measures, including password protection and secure session management.
About session tokens
You can think of a session token as a digital ID badge. These are small pieces of data or passports generated by online platforms to track user behavior while interacting with a website. When a user provides login information and is authenticated, these tokens are activated and reflect the user’s identity. These tokens are often present in her cookies, hidden fields, or sometimes in URLs.
These tokens play a vital role in the online world, facilitating seamless and customized web experiences. It’s also important to note that session tokens can be active for some time. even after the session ends. Thanks to the local storage of these tokens, users can navigate to multiple web pages without being constantly asked to re-authenticate.
Connection between authentication and session token
Session tokens play an important role in the authentication process. Here’s a quick explanation. When a user logs into an online service, the credentials provided go through a verification process. Once deemed genuine, a unique session token is created and sent to the user’s browser, where it remains for the entire online session.
Subsequent requests that the user makes to the server will be appended with this token. The server then uses this token to recognize the user, eliminating the need to repeatedly validate credentials. In essence, session tokens maintain a user’s digital “presence” and ensure smooth interaction with online services despite the inherently stateless nature of the web.
Potential flaws in multi-factor authentication
Multi-factor authentication (MFA) is praised for its enhanced security provisions that require users to go through multiple stages of verification. However, there are cracks in that armor. Once the session token is activated after navigating through MFA, it becomes the user’s passkey for that session.
This is where cyber attackers monitor for potential weaknesses. This token can be misappropriated to impersonate a legitimate user and gain access to sensitive information without additional MFA verification on her part. This vulnerability highlights the seriousness of session token theft.
A notable incident in March 2023 involved Linus Sebastian, the well-known technologist behind YouTube’s “Linus Tech Tips.” He revealed that three of his channels were compromised due to session his token compromise. Sebastian said the culprit could extract “all user data from installed browsers,” including session tokens. Such unauthorized access allowed browsers to be cloned, bypassing the need for MFA or additional credentials.
Major platforms such as YouTube, SalesForce, Microsoft 365, and Google Workspace are also not exempt from these threats. As enterprises gradually implement MFA on various SaaS platforms, cyber attackers identify browser session tokens as a coveted key to overcome tough security barriers.

Malicious browser extensions: the silent threat
When these all-important session tokens are stolen, the question arises: “How?”The answer is: Deceptive browser extensions. These extensions are often offered as useful tools to improve the user experience, but they can secretly accumulate valuable data, especially session tokens.
These extensions are carefully crafted to covertly siphon session tokens and transfer them to servers under the control of the cyber attacker. Possession of these tokens allows cybercriminals to impersonate real users and gain unauthorized access to sensitive databases.

SaaS Ecosystem: Token Theft Hotspot
The wide range of SaaS applications provides fertile ground for session token theft. Many applications require access to user data for optimal functionality, and some malicious applications abuse this privilege.
For example, a suspicious SaaS application may request access to a user’s email account. Once authorized, this application can collect session tokens within emails and then allow criminals to gain access to linked accounts.
Hardening against session token theft
Theft of session tokens can have a significant impact on your business. Not only can sensitive data be lost, but customer trust is also eroded. If your business relies heavily on online transactions, a single session token theft can lead to significant financial and reputational damage. Thankfully, many new technologies are being employed to combat these threats. An example is blockchain technology, which provides a decentralized approach to session token management, reducing the risk of centralized token theft. Machine learning algorithms are also employed to detect anomalous session usage patterns that may indicate token theft. These technologies and traditional security measures help create a layered defense against session token theft.
The prevalence of session token theft in the digital domain not only facilitates unauthorized access to critical systems, but also poses complex and evolving threats, often requiring security measures such as multi-factor authentication (MFA). Avoiding measures. Effectively combating this threat requires a multi-pronged approach, including the integration of advanced technological solutions as well as increased user education and vigilant system monitoring.
Remember that a comprehensive understanding of the risks associated with session tokens is only the first step. Safeguards such as regular audits of browser extensions, restricting access to third-party applications, and strict session management are essential to protecting individuals and organizations from the constant dangers of the cyber world.
