What Are Drive-By Downloads and How Can You Stay Safe?

Cyber threats are constantly evolving—and one of the most discreet and dangerous forms is the drive-by download.

Unlike traditional malware attacks that rely on you clicking a suspicious link or downloading a dodgy attachment, drive-by downloads happen automatically. Simply visiting a compromised website can trigger the download of malicious software without you even realising.

At Forth Tech, we believe education is the first line of defence. Here’s what you need to know about drive-by downloads and how to protect your business.

What is a Drive-By Download?

A drive-by download is a type of cyberattack where malicious software is downloaded to your device without your consent or interaction. You don’t need to click anything or open a file—in many cases, just visiting an infected webpage is enough to trigger the download.

Attackers exploit flaws or outdated code in your web browser, plugins, or operating system. Once installed, the malware can monitor your activity, steal data, or open the door to further attacks.

How Do Drive-By Downloads Work?

Here’s a typical scenario:

1. You receive a phishing email or see a fake ad (malvertising) on a legitimate-looking website.
2. You click the link or ad and land on a website that’s been compromised with malicious code.
3. The site quietly scans your device for vulnerabilities.
4. If it finds a weakness, the malware is automatically downloaded and executed—no clicks needed.

Who Is at Risk?

Any business or user can fall victim to a drive-by download, especially if your devices are running outdated operating systems or software, you don’t use antivirus or endpoint protection, staff regularly browse the web or check emails without proper security awareness or there’s no web filtering or firewall protection in place.

Small businesses are often the most vulnerable, as they may lack the dedicated security resources of larger companies.

How to Stay Safe from Drive-By Downloads

The good news is that you can significantly reduce the risk of drive-by downloads with a few proactive steps:

1. Keep software up to date
   Update your operating systems, browsers, and plugins regularly to close known vulnerabilities.
2. Use reputable security tools
   Install and maintain antivirus software and a robust firewall. Consider endpoint protection and DNS filtering for added protection.
3. Be wary of suspicious emails and ads
   Avoid clicking on pop-ups, ads, or links in emails that look even slightly unusual.
4. Restrict browser plugins
   Only use essential, trusted plugins or extensions—and make sure they come from verified sources.
5. Educate your team
   Cybersecurity awareness training can help staff spot phishing attempts, suspicious links, and risky behaviours before damage is done.
