Cybersecurity professionals can offer effective security measures when they are aware of the different types of session hijacking. They can know about the methods used by the attackers. This helps the organisation to protect its system smoothly and efficiently from being victim to session hijacking attacks. It is important to stay informed and vigilant to protect against the cybersecurity threats.
Application-Level Session Hijacking
Application-level session hijacking is a harmful cyber attack where an unauthorised individual can get control of the user’s session in the application. The attack happens when the user successfully authenticates themselves and accesses applications. The attacker can intercept and manipulate the session data to harm the user. They can get access to sensitive information and perform malicious activities on the user’s application.
Attackers can exploit vulnerabilities in the application’s session management mechanisms. Common methods come up in the form of session fixation, where the attacker sets the user’s session. Session sniffing happens when the attacker intercepts session cookies and tokens. The attacker can bypass authentication procedures and carry out unauthorised actions in the applications. This can pose a major threat to the confidentiality and integrity of the user data.
Developers can implement secure coding practices like HTTPS to encrypt communication, using strong session management techniques like token-based authentication. This regularly monitors and audits session activity for any suspicious behaviour. Users can easily protect themselves when they log out of applications when they are not in use. Moreover, they must avoid using public Wi-Fi for sensitive transactions and be aware of phishing attempts. This results in session hijacking.
Techniques Used in Application-Level Session Hijacking
Application-level session hijacking is a serious security threat in the digital world. Attackers can harm web applications to get unauthorised access to user sessions.
Session fixation
Session fixation allows the attacker to set a user’s session ID before they opt for login. This helps them control the session once the user authenticates.
Session hijacking
Attackers can get unencrypted session cookies to get into the user’s session. Attackers can steal session cookies and harm the user when they do not know about their login credentials. This technique is effective for public Wi-Fi networks where the traffic is unencrypted.
Cross-site scripting
Cross-site scripting results in session hijacking when the malicious scripts are injected into web pages to steal session information. Attackers can inject malicious scripts into the website. Attackers can manipulate session cookies and hijack user sessions. This allows attackers to execute scripts in the victim’s browser. This gives access to sensitive session information. Web developers can protect the user inputs and implement proper security measures.
Network-Level Session Hijacking
Network-level session hijacking is when an attacker intercepts and takes over the communication session between the two parties. This happens because of vulnerabilities in network protocols and with techniques like packet sniffing and capturing session data.
The attacker gets unauthorised access to sensitive information like login credentials, and financial and personal data. They can easily harm any parties involved and carry out malicious activities without any form of tracing. It is important to use encryption and secure protocols to avoid such attacks and guarantee the confidentiality and integrity of communication sessions.
One must consider it vital to implement strong encryption, use secure communication protocols like HTTPS, and regularly update the system to fix the issues and risks. Moreover, monitoring the network traffic for unusual activities results in lowering potential hijacking attempts and reduces the risks of such attacks.
Techniques used in network-level session hijacking
Network-level session hijacking is a serious security threat. Attackers can intercept and manipulate the ongoing sessions between two parties. Techniques used in network-level session hijacking are stated below:
Man-in-the-middle attacks
The attacker can place themselves between the communication flow of the two parties. This helps them block the session and change the data being exchanged between the parties without any form of knowledge between them.
Session sniffing
Attackers can easily monitor network traffic to capture session data when they use specialised tools. This happens when they try to steal sensitive information like login credentials and session tokens. This technique is the best fit for unsecured networks where the data is transferred in plain text. Attackers can intercept it and misuse the information.
Session fixation
The attacker sets a session identifier for the victim before they opt for authentication. This helps the attackers predict and control the session once the victim logs in. Attackers can then gain unauthorised access to the victim’s account and carry out malicious activities.
Difference Between Network-Level Session Hijacking and Application-Level Session Hijacking
Network-level session hijacking involves intercepting and taking the communication session between the two parties. The attack happens at the network level. Attackers can block the communication and manipulate the data being exchanged.
Application-level hijacking can target the session token and cookies used by web applications to authenticate users. Attackers can harm users and gain access to unauthorised information. Moreover, they can even perform malicious actions on behalf of the users.
Attackers can exploit vulnerabilities in the network infrastructure and protocols. This helps them manipulate and intercept the communication flow between the different parties. The attack is challenging to detect because it happens in the lower level of the networking stack. Attackers can use different techniques like cross-site scripting and session fixation to steal session tokens and hijack user sessions.
Every organisation must be vigilant and proactive to protect its networks and applications. The network-level and application-level session hijacking come up with serious security risks for individuals and businesses. It is important to follow preventive measures like:
- Secure communication protocols

How Attackers Utilise These Tools to Carry Out Session Hijacking Attacks
Attackers have different tools for carrying out the session hijacking attacks. Some of the tools which they use are stated below:
Packet sniffers
Attackers can intercept data packets exchanged between the users and the server. This helps them to capture sensitive information like login credentials and session tokens. When they analyse the packets, this allows the hackers to identify and hijack active sessions without any form of knowledge from the user’s end.
Session fixation
Āttackers can manipulate session identifiers when they force the user to authenticate with a known session ID. They can then get access to the user’s account when they log in with the compromised session ID. This method is effective when it combines with social engineering techniques to trick users into using the attacker’s session ID.
Session replay attacks
Attackers can capture the user's session data and replay it to the server. This helps them to do the following activities:
- Take the role of the attacker
- Get access to sensitive information
- Perform several malicious activities.
This method has drawbacks, as the attacker cannot encrypt the data. Moreover, this is difficult to detect and prevent.
Risks Associated with These Tools Being in the Wrong Hands
Session hijacking comes up with several threats when these tools are in the wrong hands.
- Tools like packet sniffers and session hijacking software can intercept sensitive data like login credentials and other personal information. The tools can result in theft, financial loss, and unauthorised access to private accounts.
- Developers can lose confidential information when attackers have unauthorised access to the sessions. This results in damaging the reputation of individuals and businesses. Moreover, it can violate privacy regulations and have legal consequences.
- Session hijacking tools can disrupt operations and cause financial damage. Attackers can disrupt services when they gain unauthorised access to accounts and systems, steal intellectual property, and launch cyber attacks. The financial impact of the incidents comes in the form of loss of revenue, recovery costs, and damage to the brand's reputation.
Countermeasures for Application-Level Session Hijacking
Applications can store user data and information. It is important to know about the best practices and countermeasures for application-level session hijacking. Developers can opt for secure coding practices to avoid such risks.
