Malware comes in various forms, and one of the most prevalent is known as “malvertising.” It appears across multiple platforms, from social media networks to websites. These harmful ads can even be found in Google search results.
Malvertising has become increasingly perilous for two key reasons. First, hackers are leveraging AI to make these ads appear incredibly convincing. Second, its prevalence is growing, as reported by Malwarebytes. In the autumn of 2023, malvertising increased by 42% (month over month).
Staying informed about this online threat is crucial. Understanding how to defend yourself is your best tool, especially when dealing with malicious cybercriminals. In the following, we’ll guide you through the concept of malvertising and share valuable tips on how to recognize and steer clear of it.
What Is “Malvertising?”
Malvertising involves exploiting online ads for harmful purposes. A prime example occurred during the initial release of the PlayStation 5 when its scarcity created an ideal opportunity for cybercriminals. Malicious ads flooded Google searches, appearing to direct users to official sites, but instead, they led to counterfeit pages. These fraudulent sites were crafted to steal personal information, such as login credentials and credit card details.
While Google tries to monitor and control its advertisements, hackers often manage to keep their malicious ads live for hours or even days before they are detected. These deceptive ads blend seamlessly with regular sponsored search results on Google, making them difficult to distinguish.
Malvertising isn’t limited to Google; it can also appear on popular websites that have been compromised. Additionally, it can show up in social media feeds, reaching users across a wide range of platforms.
Tips for Protecting Yourself from Malicious Online Ads
Review URLs Carefully
You may notice subtle misspellings in the URL of an online ad. Similar to phishing, malvertising frequently uses counterfeit websites. It’s essential to scrutinize any links closely for any inconsistencies or unusual details.
Visit Websites Directly
The best way to safeguard yourself is to avoid clicking on ads altogether. Instead, visit the brand’s website directly. If there’s a legitimate big sale, it will be prominently displayed there. This strategy is effective for all kinds of phishing attempts simply bypass the links and go straight to the source.
Use a DNS Filter
A DNS filter acts as a safeguard against accidental clicks by redirecting your browser to a warning page when it detects potential threats. It scans for red flags and blocks harmful sites, offering an extra layer of protection even if you inadvertently click on a malvertising link.
Do Not Log in After Clicking an Ad
Malvertising frequently directs users to fraudulent websites that closely resemble legitimate ones. The login page may appear almost identical to the real site. Phishers are after valuable login credentials, which they can sell for significant profits, especially for access to platforms like Netflix, banking sites, and others.
If you accidentally click on an ad, avoid entering your login details, even if the site seems authentic. Instead, open a new tab and visit the brand’s official website directly to ensure your safety.
Don’t Call Ad Phone Numbers
Phishing isn’t limited to the digital world it can also occur offline. Some fraudulent ads include phone numbers, leading unsuspecting victims to call. These fake representatives are part of the scam. Older adults are often the primary targets of such malvertising schemes, where they end up disclosing sensitive information to scammers over the phone.
Avoid dialling any numbers found in online ads. If you end up on a call, never share personal information simply hang up. Keep in mind that this is a well-crafted scam, designed to exploit emotions like fear and manipulate you into trusting them.
