There’s a lot of malware out there, but one sneaky player you need to know about is “malvertising.”
Ever seen an online ad that looked a little too good to be true? That’s malvertising for you—those dodgy ads lurking on social media, websites, and even Google searches. And they’re not just annoying; they’re dangerous.
Here’s the kicker: hackers are getting smarter. They’re using AI to make these malicious ads look legit. And the problem is growing fast—malvertising cases jumped 42% month-over-month in late 2023, according to Malwarebytes.
So, how do you protect yourself and your business? Knowledge is key. Let’s break down what malvertising is, how to spot it, and how to steer clear of it.
What Is Malvertising?
Malvertising is when hackers use online ads to carry out cyberattacks. Take the launch of the PlayStation 5, for example. Remember how impossible it was to find? Hackers jumped on the hype with fake ads that looked like official retailers. The unsuspecting clicked, only to end up on fake sites designed to steal their credit card details and login info.
Even though platforms like Google try to block these scams, some ads slip through the cracks for hours—or even days. Worse, malvertising doesn’t just target search results. You’ll find it on popular websites and even your social media feeds.
Tips to Protect Yourself from Malicious Online Ads
You don’t have to be a cybersecurity whiz to stay safe. A little caution and a few good habits go a long way. Here are some tips:
1. Review URLs Carefully
Ever notice a sneaky misspelling in a web address? Malvertising relies on these subtle tricks. A URL might look like your favorite brand’s site but be slightly off—designed to steal your info.
Before clicking, double-check those links. If it feels off, it probably is.
2. Visit Websites Directly
Want a foolproof way to dodge dodgy ads? Don’t click them at all. Instead, go straight to the brand’s website. If they’re really offering a killer deal, you’ll find it there. This trick works for all kinds of phishing, too.
3. Use a DNS Filter
Accidents happen, right? That’s where a DNS filter comes in handy. Think of it as your safety net—it detects dangerous sites and redirects you to a warning page before any damage is done.
If you’re not sure what a DNS filter is or if you have one, reach out. We offer managed IT services in Brisbane and Mackay to help protect businesses just like yours.
4. Don’t Log in After Clicking an Ad
You’ve clicked an ad, and it’s taken you to what looks like your bank’s login page. Stop right there. Malvertising often uses fake sites that look like the real deal. They’re designed to capture your login details.
Even if everything seems legit, don’t input any credentials. Instead, open a new browser tab and go directly to the site yourself.
5. Don’t Call Numbers from Ads
Some fake ads come with a phone number to call. These scams are particularly nasty because they prey on trust and fear. Seniors, in particular, are often targeted.
If you see a number in an ad, don’t call it. And if you’ve already dialed, don’t give out any personal information—just hang up.
6. Don’t Download Anything from Ads
“Free MS Word download!” or “Clean your PC in minutes!” Sounds tempting, right? But clicking these links could be the start of a malware nightmare. Instead of a freebie, you’ll end up with a malicious download that compromises your system.
If you need software, get it from the source. Never download anything directly from an ad.
7. Warn Others About Malvertising
Spotted a dodgy ad? Don’t keep it to yourself! Share it with your team, friends, or family. A quick heads-up can save someone else from falling into the trap.
Not sure if an ad is sketchy? A quick Google search can confirm your suspicions—plenty of scam alerts are out there.
Stay Smart and Secure
Protecting yourself starts with staying informed. By practicing good habits and sharing your knowledge, you can build a safer online community—whether it’s your family, your colleagues, or your business team.
