Session hijacking is a significant threat facilitated by infostealer malware [2]. Attackers use this method to gain unauthorized access to web applications or browser sessions [1]. There are various types of session hijacking [1], including active [1] [2], passive [1], and hybrid hijacking. Additionally, attackers can employ brute force attacks to guess session IDs and gain access [1].


Infostealer malware plays a crucial role in session hijacking. It steals device and identity data [2], including cookies [1] [2], which are then imported into an anti-detect browser to gain access to authenticated sessions [2]. Malicious links sent via email can install this malware on the victim’s machine [1], allowing attackers to steal session cookies and hijack the session [1]. Cross-site scripting is another method where attackers exploit weak security spots in a website or server to inject their own scripts and gain access to the session [1]. Session side jacking occurs when cybercriminals monitor network traffic [1], particularly on unsecured Wi-Fi networks [1], and hijack sessions by obtaining session cookies [1].

Session hijacking can bypass strong authentication methods and go undetected on corporate networks [2], providing criminals with access to sensitive information and the ability to carry out targeted attacks [2]. Overcoming this challenge requires increased threat awareness and visibility [2], educating users on infostealers [2], deleting stored cookies [2], identifying compromised data [2], and proactively invalidating sessions and resetting passwords [2]. Enhanced visibility is crucial for addressing malware-enabled security gaps and protecting company assets [2].


Session hijacking poses significant risks and can have severe consequences. It is essential to implement measures to mitigate these risks and protect sensitive information. Increasing threat awareness and visibility [2], educating users [2], and taking proactive steps such as deleting stored cookies and invalidating sessions can help prevent session hijacking. Additionally, ongoing efforts to address malware-enabled security gaps and protect company assets are crucial for maintaining a secure environment.
