Web Browser-Based Attacks: Tips for Enhancing End User Security

According to SiteLock, malicious bots create more than 60% of bot traffic on websites. This increases the risk of web browser-based attacks for all internet users, especially if they click on a high-risk website. In a web browser attack, the hacker exploits certain vulnerabilities to inject malicious code into the web components to retrieve personal data.

These attacks are more common in outdated browsers and plugins, as they are not equipped with advanced security solutions to prevent malicious activity. However, even updated browsers can fall victim to these attacks if they do not have end-user security.

End-user security offers multi-layered end-to-end protection against web-based and email-based attacks. In this blog, you will learn about browser-based web attacks and how to use end-user security practices to gain protection against this cybersecurity threat.

Types of Web Browser Attacks

Web browser attacks encompass a range of tactics, from phishing attempts that exploit user trust to sophisticated cross-site scripting (XSS) attacks targeting vulnerabilities within the browser itself.

Phishing Attacks

Phishing attacks are orchestrated with the intention of acquiring sensitive user data, such as login credentials, credit card details, and personal information. These attacks exploit victims’ trust by impersonating trusted entities and luring them into clicking malicious links.

By infecting the victim’s system with malware, hackers gain unauthorized access to valuable information, enabling unauthorized purchases, financial theft, and identity fraud. Implementing secure web browsing practices, such as accessing only trusted domains and utilizing two-factor authentication, serves as crucial measures to mitigate the risks of phishing attacks and unauthorized access attempts.

Malware attacks

A malware attack refers to a broad range of malicious programs that infiltrate end-user servers to gain access to sensitive data and carry out unauthorized activities. Several malicious browser attack examples include viruses, worms, trojans, and bots.

These malware programs are often concealed within website links, popup ads, or plugins, allowing them to gather and transfer your information secretly. Once activated, the malware scans your computer, capturing screenshots, reading the clipboard, collecting authentication cookies, and recording keystrokes. This valuable information is then transmitted to the attacker, who exploits it for financial gain. To minimize the risk of malware attacks, it is advisable to regularly change passwords and refrain from granting administrator privileges to third-party software.

Cross-Site Scripting Attacks

Cross-site scripting attacks (XSS) involve the injection of malicious scripts into a trusted website, enabling attackers to seize control over your interactions with the site. When you visit a compromised webpage, the hacker gains access to all the information you share online, which they can exploit for various purposes.

This includes impersonating you and carrying out actions on your behalf, such as unauthorized transactions, unauthorized use of your microphone, and accessing stored passwords and usernames within the browser. To safeguard your browser against XSS attacks, it is essential to employ a filtering mechanism that scans user input and encodes the HTTP response output. This helps mitigate the risk of XSS vulnerabilities.

Session Hijacking Attacks

Session hijacking attack allows the hacker to take control of a user’s browsing session and access their personal information. Most hackers use a packet sniffer to directly connect with the user’s computer and hijack their active sessions.

Session hijacking attacks are divided into two types:

  • Active Session Hijacking: The attacker intercepts and takes over a currently active session by sending a spoofed request to the target’s server and session ID.
  • Passive Session Hijacking: The attacker eavesdrops on the network traffic to access the victim’s session ID.

Regardless of the type, you can prevent session hijacking by using a VPN and keeping your software up to date.

Man-In-The-Middle Attacks

A man-in-the-middle (MITM) attack is a cybersecurity threat that involves attackers placing themselves between a user and an application, enabling them to eavesdrop on communications or impersonate one of the parties involved. The primary objective of this attack is to pilfer personal data, often targeting financial applications and e-commerce websites, to carry out unauthorized transactions.

The most effective method to prevent such attacks is to enhance end-to-end SSL/TLS encryption. This ensures the web browser’s security and thwarts cookie-hijacking attempts, providing robust protection against MITM attacks.
