A hijack attack is when an unauthorized person or entity takes over a network, system, or service without permission. This type of attack often involves the hacker gaining control and then either collecting sensitive information or causing disruptions.
Hijack Attack Examples
#1. Browser Redirection
In this scenario, you, as an internet user, are navigating your favorite online store. The intention is to browse items and, potentially, make a purchase. However, things take an unexpected turn. Without clicking on anything odd or out of place, you suddenly find yourself redirected to a completely different website.
Stay One Step Ahead of Cyber Threats
This unwanted and unexpected redirection can be an instance of a hijack attack. This specific form is often referred to as a ‘Browser Hijacking’. In such a case, a hacker manipulates your browser settings without your knowledge to take you to websites you didn’t plan to visit.
The redirected site may be intended to harvest your personal data, show you unwanted ads, or trick you into downloading malicious software. It’s a dubious tactic that hijackers use to accomplish their goal, be it data theft, spreading malware, or generating ad revenue.
#2. Man-in-the-Middle Attack
Visualize a typical day where you are using your smartphone to check your bank account, perhaps to confirm a recent transaction or monitor your account balance. To do so, you connect to a public WiFi network. Unbeknownst to you, this WiFi network is under the control of a hacker.
This scenario is a real-world example of a hijack attack, specifically known as a ‘man-in-the-middle’ attack. Here, the malicious person or entity, positioned between you and the secure bank server, effectively takes control of the communication channel.
While you think you’re securely communicating with your bank, the hacker intercepts, and potentially alters, the information you send and receive. This type of hijack attack can lead to the unauthorized access and misuse of sensitive information such as bank account numbers, passwords, and personal identification numbers.
#3. Email Account Hijacking
Consider a situation where you are trying to check your emails. You type in your usual login credentials, but you encounter some difficulty. Despite several attempts, you find that you can’t access your account. You realize that the password has been changed without your action or permission.
Situations like these typically point to a hijack attack. This is an example of ‘Account Hijacking’, which, in this case, specifically targets your email account. Unknown to you, a hacker managed to get hold of your login details, logged into your account, and changed the password, thereby locking you out.
In the process, not only have they blocked your access, but they’ve also gained control of your emails and potentially sensitive data within them. They could send out spam to your contacts, gain access to other accounts linked to your email, or engage in several other harmful activities all under your identity.
Conclusion
Hijack attacks pose real and potentially severe threats to individuals and enterprises alike. By understanding these examples, we can recognize how these attacks manifest and take appropriate actions to secure our digital assets better.
Key Takeaways

Related Questions
1. How can hijack attacks be prevented?
Prevention measures include keeping software and operating systems updated, using strong unique passwords, enabling two-factor authentication, using a trustworthy antivirus, and avoiding unsolicited or suspicious emails and websites.
2. What are the potential damages of a hijack attack?
Potential damages can range from system damage, data theft, violation of privacy, financial loss, reputation damage to identity theft, depending on the attacker’s intent and the nature of the hijacked system, network or service.
3. What’s a Ransomware attack?
Ransomware is a type of malicious software, or malware, that encrypts files on a victim’s device and then demands a ransom in order to restore access to the data.
4. Can hijack attacks be traced back to the attacker?
Tracing back a hijack attack to its source can be challenging due to the use of obfuscation methods by attackers such as IP spoofing, use of proxy servers or botnets. However, with advanced cybersecurity tools and techniques, it’s sometimes possible for cybersecurity experts to trace the origin of an attack.
5. Should law enforcement be contacted after a hijack attack?
Yes, it’s advisable to report significant cybersecurity breaches, including hijack attacks, to local law enforcement agencies. You may also need to report the incident to the relevant online service provider, your bank, or a credit bureau depending on the nature and impact of the attack.
