Protect Your Business by Recognizing and Avoiding Malvertising Threats

Have you recently clicked on an online ad, assuming it was genuine? If you answered yes, you’re certainly not alone. Unfortunately, this trust is exactly what cybercriminals rely upon. “Malvertising,” or malicious advertising, is a growing CyberSecurity threat where scammers use online advertisements to deceive you into downloading Malware, revealing private information like passwords, or even losing money directly.

Cybercriminals are getting more sophisticated every day, making malvertising an increasingly serious issue for businesses of all sizes. A critical and worrying point about malvertising is that it doesn’t always require interaction. In some instances, simply loading an infected ad in an outdated browser is enough for Malware to compromise your device.

There are three main types of malvertising techniques: scam malvertising, fake installer malvertising, and drive-by download malvertising. Here’s how each of these techniques works:

• Scam Malvertising: These ads typically appear as alarming pop-ups or banners claiming your computer has been infected with a virus or other Malware. They urge you to call a provided number for immediate assistance. Unfortunately, calling this number connects you to scammers who persuade you to install software giving them remote access to your computer. They then charge fees to “fix” a non-existent issue.

• Fake Installer Malvertising: With this technique, cybercriminals create ads leading to cloned websites that look identical to legitimate brands. Believing the site is authentic, you may download software or updates thinking they’re legitimate. Instead, you unknowingly install Malware onto your device, potentially giving hackers access to sensitive information.

• Drive-by Download Malvertising: Perhaps the most concerning type, drive-by download malvertising infects your device without you clicking on anything at all. Merely viewing or loading an infected advertisement on an outdated browser can automatically install malicious software or browser extensions.

How to Recognize and Avoid Malvertising

Awareness and vigilance are the best defences against malvertising. If you come across an ad claiming your computer has been compromised or urging immediate action, pause and ask yourself: how could this company possibly know about your computer’s health? Legitimate companies do not deliver unsolicited warnings through random online ads.

Another critical practice is verifying links before clicking. Always confirm that the ad leads to a trusted domain or website. Scammers often rely on deceptive URLs, which closely resemble legitimate ones but contain subtle differences designed to deceive.

Keeping your browser and software up to date is also vital in protecting against malvertising attacks. Software Updates regularly patch vulnerabilities that Malware exploits. Using outdated software or browsers significantly increases the risk of becoming a victim.

Educate Your Team

CyberSecurity isn’t solely an IT department’s responsibility. Every employee in your business is a potential target and your first line of defence. Regularly training your team to recognize and report suspicious ads or online activities can greatly reduce your risk.

Employees should understand the importance of not interacting with unexpected alerts or notifications claiming immediate threats. Encourage a workplace culture of caution, where verifying suspicious ads and emails becomes routine.

Creating a CyberSecurity-Focused Culture

Building a CyberSecurity-focused culture involves ongoing training and clear communication. Consider regular briefings or workshops to ensure everyone stays informed about current threats, such as malvertising. A simple conversation about the dangers of suspicious ads can go a long way towards protecting your business.

Additionally, consider adopting security tools designed to detect and block malicious advertising content automatically. These solutions can complement employee vigilance by adding another layer of security.

Staying Ahead of Malvertising

The landscape of malvertising continues to evolve, with scammers constantly developing new methods to deceive. Businesses must remain proactive in their CyberSecurity strategies. Regular reviews of your digital security practices and staying informed about emerging threats are crucial steps in staying ahead.

Consider subscribing to security advisories or newsletters focused on CyberSecurity. These resources can provide timely information about the latest malvertising schemes and Malware threats, empowering your business to react promptly.
