The Ultimate Guide to Drive by Download Malware


What is a Drive-by Download Attack and How to Prevent It?




Have you ever visited a website and noticed that your computer started to act strangely or slow down? Or have you ever clicked on an online ad or a link that promised you something too good to be true? If so, you might have been exposed to a drive-by download attack, one of the most common and stealthy cyberattacks on the internet.


Introduction




A drive-by download attack is an unintentional download of malicious code, file or software onto your computer or mobile device. It involves the involuntary download of malicious code, file or software onto a computer or mobile device. Cybercriminals may use drive-by downloads to harvest your personal information, spy on you, inject banking Trojans, or infect your entire network with malware. You don't have to click on anything, press download, or open a malicious email attachment to become infected.

A drive-by download attack can take advantage of an app, operating system, or web browser that contains security flaws due to unsuccessful updates or lack of updates. Unlike many other types of cyberattack, a drive-by doesn't rely on the user to do anything to actively enable the attack. Drive by downloads are designed to breach your device for one or more of the following:


  • Hijack your device to build a botnet, infect other devices, or breach yours further.



  • Spy on your activity to steal your online credentials, financial info, or identity.



  • Ruin data or disable your device to simply cause trouble or personally harm you.



Without proper security software or fixes for your vulnerabilities, you could become a victim of a drive by download attack.


Types of Drive-by Download Attacks




There are two main types of drive-by download attacks: authorized and unauthorized. Authorized drive-by download attacks involve tricking you into clicking on a link or downloading a file that contains malware. For example, you might see a fake security alert or an ad that prompts you to update your software. Unauthorized drive-by download attacks involve infecting your device without any notification or warning. For example, you might visit a compromised website that automatically downloads malware onto your device.


Drive-by download attacks can also be classified by the methods they use to deliver malware. Some common methods are malicious ads and exploit kits. Malicious ads are online advertisements that contain malicious code or redirect users to malicious websites. Exploit kits are toolkits used by attackers to automate the process of finding and exploiting vulnerabilities in users systems, allowing the download and installation of malware silently.

Some examples of drive-by download attacks include:


  • The Mac Flashback outbreak: In March 2012, the Flashback trojan infected nearly 600,000 Mac systems via drive-by downloads. Attackers created a fake toolkit for WordPress-based blogs which infected the users who installed the toolkit with the Flashback trojan.



  • The Nuclear exploit kit: In April 2016, researchers discovered that hundreds of thousands of users were exposed to the Nuclear exploit kit via malicious ads on popular websites. The exploit kit scanned users browsers for vulnerabilities and delivered ransom ware to the users who had outdated versions of Adobe Flash, Java, or Silverlight.



  • The Stegano exploit kit: In December 2016, researchers uncovered a sophisticated drive-by download campaign that used malicious ads to infect users with malware. The ads contained a hidden code that scanned users systems for vulnerabilities and redirected them to the Stegano exploit kit, which downloaded and executed various malware payloads.



How to Protect Yourself from Drive-by Download Attacks




Drive-by download attacks can be hard to detect and prevent, but there are some steps you can take to reduce your risk of infection. Here are some tips to help you stay safe online:


  • Keep your computer and browser updated: One of the best ways to protect yourself from drive-by download attacks is to keep your operating system, web browser, and other software updated with the latest security patches. This will help you fix any known vulnerabilities that attackers might exploit.



  • Use a reliable security software and firewall: Another way to prevent drive-by download attacks is to install and run a reputable antivirus or anti-malware program on your device. This will help you scan and remove any malicious files or programs that might have been downloaded onto your device. You should also enable a firewall on your device to block any unauthorized network traffic.



  • Avoid suspicious websites and links: A common way to avoid drive-by download attacks is to be careful about what websites you visit and what links you click on. You should avoid visiting websites that have a low reputation, contain illegal or pirated content, or offer free downloads of software or media. You should also avoid clicking on links or attachments in emails or messages from unknown or untrusted sources.



  • Install an ad blocker and a script blocker: Another way to avoid drive-by download attacks is to install an ad blocker and a script blocker on your browser. An ad blocker will help you block any malicious ads that might contain malware or redirect you to malicious websites. A script blocker will help you disable any scripts that might run automatically on websites and download malware onto your device.



  • Check the website certificates and reputation: A final way to avoid drive-by download attacks is to check the website certificates and reputation before visiting them. A website certificate is a digital document that verifies the identity and security of a website. You can check the website certificate by looking for a padlock icon or a green address bar on your browser. You can also check the website reputation by using online tools such as Google Safe Browsing or Norton Safe Web.



Conclusion




Drive-by download attacks are one of the most common and stealthy cyberattacks on the internet. They involve the involuntary download of malicious code, file or software onto your computer or mobile device without your knowledge or consent. They can cause serious damage to your device, data, and privacy.


To protect yourself from drive-by download attacks, you should keep your computer and browser updated, use a reliable security software and firewall, avoid suspicious websites and links, install an ad blocker and a script blocker, and check the website certificates and reputation. By following these tips, you can reduce your risk of infection and enjoy a safer online experience.
