Malvertising 101: How to Spot and Avoid Malicious Online Ads

Protect Yourself from Malvertising: A Growing Online Threat

Ever seen an ad online that looks too good to be true? It might be malvertising—one of the most common types of malware. These malicious ads appear everywhere, from Google searches to social media feeds. And they’re becoming more dangerous.

Why? Cybercriminals are using AI to make their scams incredibly convincing. Malvertising increased by 42% in late 2023, according to Malwarebytes. Staying informed is your first line of defence. Let’s dive into what malvertising is and how to avoid falling victim.

What Is Malvertising?

Malvertising uses online ads to trick people into clicking dangerous links. For example, during the PlayStation 5 craze, scammers posted fake ads leading to look-alike websites. Instead of finding a console, victims had their credentials or credit card details stolen.

These ads can show up on trusted websites or social media platforms, hiding in plain sight until discovered and removed.

How to Stay Safe from Malicious Ads

1. Examine URLs Closely

Watch for slight misspellings or unusual characters in a link. Hackers often mimic legitimate websites.

2. Visit Websites Directly

Skip the ad link and go straight to the brand’s official website. If there’s a genuine sale or offer, it’ll be there.

3. Use a DNS Filter

A DNS filter can block malicious websites automatically, even if you click a harmful link.

4. Avoid Logging In via Ads

Don’t enter your login credentials after clicking an ad, even if the site looks real. Open the site in a new tab instead.

5. Ignore Ad Phone Numbers

Some ads include phone numbers to call. These are often scams designed to steal personal information.

6. Never Download from Ads

Avoid clicking direct download links in ads. These often install malware instead of the promised software.

7. Warn Others

If you spot a suspicious ad, share your knowledge with friends and family. Together, you can build a safer online community.
