Picture this: You are logged into your company dashboard, looking through sensitive information, when suddenly a cybercriminal gains access to all of it, without you giving out your password. Sounds scary? This is something that session hijacking can do.
Cyberattacks today are no longer restricted to large companies. Even locally operated and mid-tier businesses on Long Island are becoming prime targets for cybercriminals and one of the most ignored dangers is session hijacking. Here at B&L PC Solutions, we have set out to turn that around by enabling companies to learn about, detect, and defend against this silent threat.
This comprehensive guide will provide you with everything you need to know about session hijacking, how it occurs, the various types of attacks, the real-life effects of attacks, and what services we may offer cybersecurity services on Long Island to keep your business safe.
What is Session Hijacking?
Session hijacking is a type of cyber-attack technique in which hackers access or steal valid session tokens (e.g., cookies or authentication IDs) and act as valid users to access systems. The hackers access applications or information that no one is supposed to know other than an authentic user. These tokens are digital keys that establish the identity of a user during post-login, and a hacker can decode the authentication mechanisms, like MFA, and work under malicious accounts that can’t be noticed easily.
The methods like session sniffing (monitoring unsecured traffic), side-jacking (taking advantage of easy-to-decrypt traffic), and cross-site scripting(XSS) injection of harmful scripts to grab tokens. Once cybercriminals steal a session, they are able to make bogus transactions, obtain access to confidential databases, impose ransomware, etc.
According to a reliable report, session hijacking attacks often target cloud-native enterprise platforms, with attackers using stolen tokens to move laterally across networks. Businesses are faced with increased vulnerabilities with remote work and the migration of work to the cloud, expanding the exposed areas of attack. The proactive measures involve using HTTPS encryption, regularly changing session IDs, and launching zero-trust systems to verify disabled tokens in real-time.
What Is a Session?
A web session is an active interaction between a user and a web application, commencing when a user logs in and finishing when the user logs out, or the connection times out. To ensure consistency in communication, applications assign a particular session ID (typically in browser cookies or URL parameters) to allow session data to be carried across to subsequent communications. It is the identifier that can be treated as a short-term credential that the user can use to present to the server to identify them on the succession of page requests without demanding authentication again and again.
Sessions also allow one to have a custom experience, e.g., saving something in a shopping cart or staying signed in to a mailing service. But when session IDs are stolen or illegally copied, they can be used to hijack associated authenticated sessions by the attackers and to act as legitimate users. To counter this risk, efficient session management, such as encryption, short token duration, and safe storage, is essential, especially with workflow in the cloud increasing the surface of attack.
Types of Session Hijacking
Session hijacking is normally performed through numerous strategies, and some of the most prevalent methods are:
- Session Sniffing: This is one of the simplest ways to do application layer hijacking of sessions, where attackers use sniffers (i.e., Wireshark) or proxy servers, like OWASP Zed, to capture and sniff session data as they are sent back and forth between the server and the user. This will enable them to use a token to capture the valuable session data.
- Predictable Session Token ID: In case the websites use predictable token IDs generated with predictable variables or based on rules, the attackers can guess or figure out the token easily because it is predictable.
- Man-in-the-Browser: This mode of attack is comparable to a man-in-the-middle attack but involves infecting the victim with a Trojan first. When installed, the malware sites await the victim to visit a target site. It is capable of secretly altering transaction records and generating new transactions without the consent of the user. As the requests are initiated on the side of the victim, the device itself, it becomes difficult to identify fraudulent requests by the web service.
- Cross-Site Scripting (XSS): The hacker uses loopholes in web applications to insert malicious code into web pages, visible to the rest of the users. It may cause loss of session information and session hijacking.
- Session Sidejacking: In this attack, hackers seize session information when it is in transit, typically through weak encryption or no encryption, allowing them to access the user session.
- Session Fixation: Hackers manipulate users into using a particular session ID that they already know, they therefore gain access to that particular session after the user logs in.
Impacts of Session Hijacking
Session hijacking may lead to serious penalties for both individuals as well as organizations. The following are five major effects of an effective attack on session hijacking:
- Data breach: An attacker will be able to obtain information that is sensitive to the individual or the business, and the activity may result in identity theft, financial fraud, or even corporate espionage.
- Financial loss: Hijackers can make illegal money transfers, initiate illegal money transactions, make purchases, or even steal the account of the victim.
- Reputational harm: Companies compromised by session hijacking may have to face severe reputational losses, loss of trust issues from clients, and lower revenue flow.
- Illegal access to the system: There is also a risk of unauthorized access to the system where single sign-on (SSO) is in use; hijacking of a session may provide malicious parties with an exponentially larger attack surface.
- Compliance violation: Session hijacking can lead to a violation of compliance with data protection rules, subject to legal consequences and substantial fines or penalties.
Tips to Detect and Prevent Session Hijacking
| Action | Detection | Prevention |
|---|---|---|
| Monitor Session Activity | Look for unusual IP addresses, locations, or session durations. | Set session timeout limits and monitor concurrent logins. |
| Use HTTPS Encryption | Detect missing or invalid SSL certificates on suspicious pages. | Enforce HTTPS across all pages to encrypt session data. |
| Inspect Login Patterns | Track abnormal login times or devices not used before. | Put MFA (multi-factor authentication) in practice. |
| Network Traffic Evaluation | Monitor closely unauthorized traffic or unexpected session tokens. | Use VPNs and secure systems only for the protection of your data in transit. |
| Token Validation | Monitor for reused or expired tokens being accepted. | Use short-lived session tokens and regenerate after login or inactivity. |
| Alert Triggers | Configure notifications for multiple failed login attempts or rapid session changes. | Configure intrusion detection systems (IDS) to study deviations in sessions. |
| User Logout Tracking | Check for sessions that remain active after logout events. | Force a logout on inactivity and disable back-button reentry to sessions. |
| Browser/User Agent Checks | Detects sessions accessed from inconsistent browser agents. | Link the session tokens to the users and IP addresses. |
| Client-Side Security | Spot signs of script injections or cross-site activity. | Make use of secured cookie flags (HttpOnly, Secure, SameSite) & CSP headers. |
