Through browsers, users gain access to the digital space, where they can view content from all over the world. Browsers now also store credentials, cookies, search histories, and other valuable information about users that could be targeted by cybercriminals.

Attackers can carry out attacks to remotely control a device or gain access to a connected network. In addition, advertisers or other third parties may collect personal data through the browser.

In this regard, ESET specialists have prepared a list of the most common browser security threats and risks, as well as tips to help protect against intruders while browsing the web.

1. Presence of vulnerabilities

Due to the fact that users often neglect to apply regular updates, the browser and installed plugins or extensions may contain vulnerabilities. They are used by attackers to confidential data theft or downloading malicious software. Attacks often begin with a phishing email or message, or visiting an infected site with malware and downloading a dangerous file.

2. Use of programs

The attackers target programs on the computer, and the browser is used to deliver or execute a malicious component.

3. Malicious plugins

There are thousands of plugins that users can download to improve their browsing experience. However, many of them have privileged browser access. This means that attackers can disguise malicious plugins as legitimate ones and use them to steal data and download dangerous software.

4. Man-in-the-Middle Attacks

During this type of attack, the attacker can modify the traffic, such as redirecting the victim to a phishing page, downloading ransomware, or stealing credentials. This risk increases when using public Wi-Fi networks.

5. Domain Name System (DNS) Infection

DNS is an Internet address book that converts entered domain names into IP addresses for display in a website browser. However, attacks on the domain name system that is stored on a computer or on the servers themselves can allow attackers to redirect users’ browsers to malicious domains, including phishing sites.

6. Session hijacking

Most websites use session IDs when users log in. If attackers manage to crack or intercept these identifiers (in the absence of encryption), cybercriminals can enter the same sites or programs under the guise of a user. In this case, you can quickly steal confidential data and financial information.

All of these scenarios are common among attackers who want to steal sensitive user data. In addition, you should not forget about the large number of cookies that contain data about page views by site visitors. This information is collected by ISPs, websites and advertisers.

On the one hand, cookies store information that can make search results more personalized, such as displaying relevant ads or storing login credentials to quickly enter a site. But on the other hand, they also raise privacy concerns and pose the risk of hackers gaining access to user sessions.

How to improve browser security

To prevent potential threats to browser security and privacy while browsing the web, you should follow the following tips.

Update your browser and installed plugins to minimize the chances of exploiting vulnerabilities, and remove any outdated plugins.

Only visit secure sites using the HTTPS protocol, as evidenced by the padlock in the address bar. In this case, hackers will not be able to intercept traffic from the browser to the web server.

Beware of phishing threats that spread through email and online messages. Never reply to unsolicited emails without verifying the sender’s details, and don’t send sensitive information to strangers.

Do not download suspicious programs or files, and if necessary, use only official resources for this.

Use multi-factor authentication to reduce the risk of credential theft.

Use a VPN from a trusted provider, not the free version. This will create an encrypted tunnel for Internet traffic and protect you from being tracked by third parties.

Download a multi-layer solution to protect computers and mobile devices from various online threats.

Turn on automatic updates for the operating system and software on your device.

Review your browser’s privacy and security settings to prevent tracking and block third-party cookies and pop-ups.

Disable automatic password saving in your browser.

Use private browsing settings such as Chrome Incognito to prevent tracking cookies.
