Think about the last online ad you clicked. Did you just assume it was genuine? If you said yes, you’re not alone – and this is exactly what scammers count on “Malvertising”, or malicious advertising!
This is where scammers use online ads to trick you into downloading malware (malicious software), sharing sensitive information like passwords, or even handing over money.
These attacks are becoming increasingly sophisticated, and they pose a growing threat to businesses of all sizes. Worse yet, you don’t even need to click on these ads to become a victim; loading the ad in an outdated browser can be enough to compromise your device.
The three most common malvertising techniques are scam malvertising, fake installer malvertising, and drive-by download malvertising.
Here’s a little more about them so you can be more aware:
- Malvertising scams are where an ad claims that your computer is infected and urges you to call for support. Once you do, the scammers convince you to install software that gives them control over your system. Then, they charge you to “fix” the fake issue.
- Fake installer malvertising often uses ads that redirect you to cloned websites of trusted brands. You download software, thinking it’s legit… but you’re downloading malware onto your device instead.
- Drive-by download malvertising is where ads infect your computer without you even clicking on anything. This malvertising exploits outdated browsers and automatically installs malicious files or extensions.
Recognising these scams is the first step to keeping your business safe. If you see an ad claiming you’ve been hacked or urgently need to act, stop and think. How would this company even know anything about your computer?
Also, be sure to double-check links before clicking. If the link isn’t sending you to a legitimate domain, steer clear. Most importantly, make sure you’re running the latest version of your browser, as updates patch vulnerabilities that malvertising often exploits.
Don’t forget to share this knowledge with your employees, too. They’re your first line of defence – and training them to spot suspicious ads can save your business from serious trouble.
