Cybersecurity threats come in many forms, but one of the fastest-growing dangers is malvertising. This malicious tactic uses fake online advertisements to target unsuspecting users. Shockingly, you can encounter malvertising everywhere—from your favorite social media platforms to popular websites and even Google search results.
Two factors make malvertising particularly hazardous today:
- Hackers are leveraging AI tools to make these malicious ads more convincing than ever.
- Malvertising is rapidly increasing, with a 42% month-over-month rise reported by Malwarebytes in late 2023.
To protect yourself, it’s crucial to understand how malvertising works and learn to recognize its signs. Below, we’ll explain what malvertising is and share actionable tips to help you stay safe online.
What Is Malvertising?
Malvertising refers to the use of deceptive online ads to carry out malicious activities. Cybercriminals often disguise these ads as legitimate promotions to lure victims.
For example, when the PlayStation 5 first launched and demand far outweighed supply, hackers saw an opportunity. Fake ads appeared on Google search results, mimicking official retailers. Victims who clicked these ads were redirected to fraudulent sites designed to steal sensitive data such as login credentials and credit card details.
Although companies like Google actively monitor and remove harmful ads, hackers often succeed in running their schemes for hours or even days before detection. Unfortunately, malvertising is not limited to search engines. It can also appear on:
- Well-known websites that have been compromised.
- Social media platforms like Facebook and Instagram.
How to Protect Yourself from Malicious Ads
While malvertising can be convincing, you can take steps to protect yourself from falling victim to these scams. Here are some practical tips to stay secure:
1. Inspect URLs Carefully
Before clicking an ad, take a close look at its URL. Malicious ads often lead to websites with slightly altered spellings or extra characters in their domain names. These copycat sites aim to trick you into entering sensitive information.
2. Visit Websites Directly
One of the safest strategies is to avoid clicking ads altogether. Instead, navigate directly to the official website by typing the URL into your browser. If a retailer is genuinely running a sale or promotion, you’ll find it on their official site.
3. Use a DNS Filter for Extra Security
A DNS filtering tool can help block harmful websites automatically. If you accidentally click a malicious ad, the filter will redirect you to a warning page instead of allowing access to the dangerous site.
4. Avoid Logging in After Clicking an Ad
Malvertising often leads to websites that mimic login pages for popular services like Netflix or your bank. If you land on such a page, avoid entering your credentials. Instead, close the tab and visit the official site directly through a separate browser window.
5. Never Call Phone Numbers in Ads
Some malicious ads display phone numbers, targeting unsuspecting users through offline phishing schemes. Victims, especially seniors, may call these numbers and unknowingly share sensitive information with scammers. To stay safe:
- Refrain from calling numbers listed in online ads.
- End any suspicious calls immediately without revealing personal details.
6. Don’t Download Software from Ads
Scammers often use enticing phrases like “Get a Free PC Cleaner” or “Download Microsoft Office for Free” to lure users into downloading malware. These downloads can infect your device, giving hackers access to your data. Always download software directly from trusted sources.
7. Warn Others About Malvertising
If you come across a suspicious ad, share your concerns with friends, family, or colleagues. Raising awareness can help others avoid falling victim to the same scams. You can also research questionable ads online, where scam alerts are often posted.
Build a Safer Online Environment
By staying informed and proactive, you can protect yourself and help others navigate the growing threat of malvertising. Building a cyber-aware community ensures stronger online security for everyone.
