What is Browser Hijacking, and How Can it Be Prevented?
Browser hijacking often involves the secret installation of supplementary programs by entities ranging from legitimate software companies to cybercriminals or even a hybrid of both. This unauthorised insertion alters the browser’s behaviour without explicit user consent, compromising user privacy and security. To effectively address browser hijacking, it is essential to recognise its mechanisms, manifestations, and potential impacts on user privacy and security. By maintaining vigilance and implementing robust protective measures, users can mitigate the risks associated with these digital threats.
Browser hijacking is considered one of the trends of concern in cybersecurity, a significant threat to users’ safety and privacy. In most instances, computer users want to know how to protect against threats that invade their privacy.
Browser hijacking is a sophisticated intrusion that occurs when unwanted software or an internet browser alters the browser’s activity without the user’s explicit consent. This digital intrusion transforms the browser, the primary gateway to the internet, into a potential tool for cybercriminals.
Let’s understand browser hijacking in detail.
How does Browser Hijacking Work?
Browser hijacking can compromise devices through various methods, such as malicious email attachments, infected files, or visiting infected websites. The browser hijacking software could be attached to a browser extension or part of the browser itself. Additionally, such malware can be distributed through shareware, freeware, adware, and spyware infections.
Browser hijacking is facilitated through deceptive means. Users may be tricked into inadvertently consenting to the installation of these malicious components by being misled about the terms and conditions of software agreements. This often involves a deliberate obfuscation of options designed to confuse the user into accepting the unwanted software. Once installed, the hijacker’s embedded code starts altering the activity of the user’s browser.
The browser modification targeted by browser hijacking can vary depending on the hijacker’s impact. Some hijackers effectuate only minor changes, such as the integration of unsolicited toolbars, which cause user inconvenience instead of direct harm. Conversely more dangerous variant of hijacking may target the Domain Name System (DNS) to direct users to malicious websites, possibly to acquire sensitive details and user credentials.
The Impact & Risk of Browser Hijacking
Malicious actors and organisations deploy or inject their software into their browsers for several reasons:
Information Theft: These intrusions are often aimed at surreptitiously extracting sensitive information from users. This can include personal identification details, financial data, and other confidential information.
Surveillance: Malicious actors may employ browser hijacking to conduct covert surveillance, monitoring user activities and behaviour without consent.
Persistent Advertising: Some attackers use hijacking techniques to inundate users with persistent, often intrusive, advertisements. These ads can generate revenue through click-through rates or promote particular products aggressively.
Aggressive Marketing Tactics: Browser hijacking can also be leveraged to implement high-pressure sales tactics, such as try-before-you-buy schemes, wherein users are enticed or coerced into purchasing software or services under misleading pretences.
How to Prevent Browser Hijacking
Regularly Update Software
Regularly update your apps, software, and devices to address security vulnerabilities. These updates often contain critical patches that address security vulnerabilities in older versions and help against weaknesses that hackers can exploit.
Avoid Suspicious Links
Avoid clicking on suspicious links and email attachments from untrusted sources. Such action can introduce browser hijackers or other harmful malware into your device.
Be Careful When Downloading Software
When installing applications or programs, use legitimate marketplaces or verified websites. Trusted platforms such as Microsoft Store, Google Play, and the App Store vet their offerings for security. Direct downloads from reputable sites are also preferable.
Avoid Freeware
Free software often comes with hidden risks. Browser hijackers can be embedded into free software, leading to unauthorised access to your browser. Exercise caution and evaluate the credibility of freeware before installation.
Use A Secure Browser
Opt for browsers that prioritise security and privacy, such as Norton Secure Browser or Brave. Such browsers are designed with advanced features to protect against various online threats, including hijacking.
Use Antivirus Software
Install and maintain reputable antivirus software to detect and block harmful downloads. Effective antivirus programs can safeguard your system from browser hijackers and other malicious threats.
Conclusion
Browser hijacking is a recognisable threat that affects both organisations and individuals. It represents a notable threat in the contemporary cyber landscape, jeopardising online privacy, security, and overall computer performance. Comprehending the nature of browser hijacking, recognising its indicators, and implementing effective protective measures are crucial for safeguarding a secure browsing experience. By adopting a proactive approach to cybersecurity, users can navigate the internet more confidently, minimising the risk of compromising their privacy and security.
