Beware of Google Search Ads – Malvertising Is Spiking!
There’s a wide variety of malware out there, but one of the most common and cunning is “malvertising.” These malicious ads can appear everywhere – from social media feeds to Google searches and even reputable websites.
Recent data from Malwarebytes shows malvertising is becoming increasingly common, with a 42% month-over-month spike in late 2023. What makes this tactic even more dangerous? Cybercriminals are now leveraging AI to craft incredibly convincing ads.
Understanding malvertising and learning how to recognize it is crucial to staying safe online. Below, we’ll outline what malvertising is and provide actionable tips to avoid falling victim to these schemes.
What Is Malvertising?
Malvertising involves embedding harmful content into online advertisements. For instance, when the PlayStation 5 first launched and demand skyrocketed, fake ads emerged in Google searches. These ads mimicked legitimate sellers but directed users to fraudulent sites designed to steal login credentials and payment details.
While Google works hard to detect and remove these harmful ads, they can still linger for hours or days before being flagged. And malvertising isn’t limited to Google—it can surface on hacked websites and social media platforms as well.
How to Protect Yourself From Malicious Ads
Scrutinize URLs
Always check web addresses carefully. Malicious ads often lead to sites with slight spelling errors or other subtle inconsistencies.
Go Directly to Websites
Avoid clicking on ads altogether. If you see a promotion, visit the company’s website directly to verify it.
Use DNS Filtering
A DNS filter adds an extra layer of security by blocking access to harmful sites. If you accidentally click a malicious ad, a DNS filter can redirect you to a warning page.
Avoid Entering Login Information After Clicking Ads
Copycat websites often mimic legitimate login pages. To stay safe, never enter your credentials on a site you’ve reached through an ad. Instead, navigate directly to the official site.
Don’t Call Numbers Listed in Ads
Some malvertising campaigns include fake customer service numbers. Always verify contact information through official channels.
Avoid Downloading Files From Ads
Be cautious of offers like “free software” or “system cleaners” in ads. These often carry malware that can infect your device.
Warn Others About Suspicious Ads
If you come across a malicious ad, share the warning with friends, colleagues, or family members. The more aware people are, the safer they’ll be.
