Vulnerabilities through Browsers

web browsers such as Microsoft Internet Explorer, Mozilla Firefox, and Apple Safari are installed on almost all computers. Because web browsers are used so frequently, it is vital to configure them securely. Everyone uses browsers to access a wide range of networked systems, from shopping sites to enterprise management. As a result, browsers collect tons of sensitive information — from passwords to credit card data — that hackers are eager to get their hands on.

A new report by Atlas VPN has revealed that with 303 vulnerabilities in 2022, Google Chrome is the most vulnerable browser so far this year. It's also the all-time leader, with 3,159 cumulative vulnerabilities since its inception. It is followed by Mozilla Firefox, with 117 vulnerabilities, and Microsoft Edge, with 103 vulnerabilities whereas Apple's Safari browser documented 26 vulnerabilities in 2022.

Every month, we see increasing newer Web browser vulnerabilities. Often, the web browser that comes with an operating system is not set up in a secure default configuration. Not securing your web browser can lead quickly to a variety of computer problems caused by anything from spyware being installed without your knowledge to intruders taking control of your computer.

The reason being, most of the computers are sold with software already loaded. Whether installed by a computer manufacturer, operating system maker, Internet service provider, or by a retail store, the first step in assessing the vulnerability of your computer is to find out what software is installed and how programs will interact with each other.

Hackers use multiple techniques to exploit browser vulnerabilities. Occasionally, they will discover a vulnerability that enables them to download and execute malicious code when a user simply visits a compromised site. From there, the code can download other malicious packages or steal sensitive data. Plug-ins are a common vector for these "drive-by download" attacks.

There is an increasing threat from software attacks that take advantage of vulnerable web browsers. Attackers focus on exploiting client-side systems (your computer) through various vulnerabilities. They use these vulnerabilities to take control of your computer, steal your information, destroy your files, and use your computer to attack other computers.

A low-cost method attackers use is to exploit vulnerabilities in web browsers. An attacker can create a malicious web page that will install Trojan software or spyware that will steal your information.

Going forward, the organizations should combine multiple techniques to reduce their risk from browser vulnerabilities. The first is to keep all browsers updated. However, patching browsers can be problematic.

A report says that 83% of users run versions of Chrome that are vulnerable to zero-day attacks that have already been identified by Google. One reason is simply that many users do not like rebooting their browsers, which is most essential to update.
