Have you ever clicked on an online ad without giving it a second thought? If so, you’re not alone—and that’s exactly what scammers are hoping for.
Malvertising (short for “malicious advertising”) is when attackers use online ads to spread malware, trick you into giving up sensitive information, or redirect you to fraudulent websites. These attacks are becoming more common, more convincing, and more dangerous—especially for businesses that aren’t prepared.
At Systemic Digital, we help businesses strengthen their defenses against threats like this. Here’s what you need to know to stay protected.
What Makes Malvertising So Dangerous?
Unlike traditional phishing, malvertising doesn’t always rely on your actions. In some cases, just loading a malicious ad in an outdated browser can be enough to compromise your device—no clicking required.
There are a few types of malvertising you should be aware of:
- Scam Malvertising
These ads mimic legitimate warnings, telling you your computer is infected. They often include a phone number to call for “support.” Once you call, scammers walk you through installing remote access tools so they can control your device—then charge you to “fix” a problem that didn’t exist. - Fake Installer Malvertising
These ads lead to fake websites that look like real software providers. You think you’re downloading a trusted application, but you’re actually installing malware. - Drive-By Download Malvertising
The most concerning of all: these ads don’t need clicks. If your browser or plugins are outdated, simply viewing a page with a malicious ad can trigger an automatic download of harmful software.
How to Spot and Avoid Malvertising
Staying safe from malvertising starts with awareness. Here are some practical tips to reduce your risk:
Be skeptical of ads that claim your device has a problem—especially ones urging you to act immediately or call for help.
Always double-check the destination URL before clicking any online ad.
Keep your browser and software fully updated. Many malvertising attacks rely on known security flaws in outdated software.
Use a modern ad blocker and reputable antivirus solution for an added layer of protection.
And don’t forget—your team plays a critical role in defending your business. If they can recognize the signs of a scam, they’re far less likely to fall for one.
Train Your Team. Protect Your Business.
Scammers rely on users trusting too quickly. The more informed your employees are, the harder it becomes for cybercriminals to succeed. At Systemic Digital, we offer cybersecurity training and managed IT services to help your team recognize threats like malvertising before they become a problem.
