Malvertising: How to Spot and Safeguard Against Malicious Ads
Malvertising, a form of malware delivered through online advertisements, has become one of the most prevalent cyber threats today. From social media platforms to search engine results, malvertising can appear almost anywhere. Its reach is expanding rapidly, with hackers increasingly leveraging artificial intelligence to create convincing scams. Recent reports by Malwarebytes reveal a staggering 42% month-over-month increase in malvertising in late 2023, making it essential for users to understand and defend against this menace. In this article, we’ll explore the concept of malvertising, its dangers, and how you can protect yourself. Knowledge is the first step toward staying safe online.
What is Malvertising?
Malvertising refers to malicious online advertisements designed to deceive users and compromise their security. For example, during the launch of the PlayStation 5, scammers exploited its scarcity by placing fake ads on search engines like Google. These ads appeared legitimate, leading users to counterfeit websites. Once there, unsuspecting victims would often surrender sensitive information, such as login credentials and credit card details. Despite Google’s efforts to monitor and remove harmful ads, malvertising campaigns can persist for hours—or even days—before detection. These malicious ads don’t just target search engines; they also infiltrate hacked websites and social media platforms.
Tips to Stay Safe Online
Watch for Odd Details in URLs
Hackers often disguise malicious links with URLs that mimic legitimate websites. Check carefully for minor misspellings or strange characters before clicking.
Go Straight to the Source
Instead of clicking on ads, type the website’s URL directly into your browser. If there’s a promotion or sale, it will be featured on the official website.
Use Technology to Block Threats
A DNS filter can act as an effective safeguard, blocking malicious websites if you accidentally click on a harmful link.
Avoid Entering Your Credentials After Clicking Ads
Some ads may lead to fake login pages designed to steal your account credentials. Always verify the website’s authenticity before logging in.
Don’t Rely on Ad Contact Numbers
Be cautious of ads promoting phone numbers for customer support. These can be part of phishing scams targeting personal information.
Skip Downloads from Ads
Avoid clicking on direct download links in ads. These are often designed to inject malware onto your device.
Share What You Learn
If you encounter a suspicious ad, warn others. Share your findings with colleagues or friends to help them stay protected.
Improving Your Cybersecurity
Strengthening your defenses against malvertising starts with proactive security measures. Ensure your devices are updated regularly, use reliable anti-malware software, and enable DNS filtering to block harmful websites.
