LAS VEGAS (FOX5) — Unlike traditional malware that requires a user to click a suspicious link or file, a newer generation of malicious software can install itself onto devices without direct user interaction.
How drive-by downloads work
The process typically begins with an email or text message directing users to a malicious website. Once on the site, the software scans the user’s browser for vulnerabilities — such as outdated security software. If a weakness is found, malware downloads automatically onto the device and can steal sensitive information.
Cybercriminals also embed infected advertisements on legitimate websites. Clicking one of those ads can result in a virus being downloaded to the user’s device.
How to protect yourself
Keeping software updated is the most effective defense against drive-by downloads. Users should also exercise caution when clicking links in text messages, emails, or online advertisements, as cybercriminals use all three methods to direct targets to malicious web pages.
Experts also recommend using only trusted browser extensions and limiting the number of plugins installed, as those types of software can increase the risk of unintentional infection.
