The internet represents the largest market worldwide, and traditional forms of advertising such as television or magazine ads have been almost fully replaced by online advertising. But as online ads fuel the internet economy, a looming threat has steadily grown alongside them: malvertising

Short for malicious advertising, malvertising refers to the use of online ads to spread malware and conduct various cybercrimes. This clandestine tactic not only undermines user trust but also poses significant risks to brands. Let's delve deeper into this rising threat and explore how it impacts both users and businesses, along with the solutions available to combat it.

What is Malvertising? 

Malvertising operates under the guise of legitimate online advertisements. Cybercriminals leverage ad networks to inject malicious code into seemingly harmless ads, which are then distributed across websites and platforms frequented by millions of users. These ads can take various forms, including pop-ups, banners, and even sponsored content, making them difficult to distinguish from genuine ads. 

How does Malvertising work? 

The mechanics of malvertising are deceptively simple yet highly effective. Let's say a cybercriminal wants to compromise an online ad to distribute malware. They might start by creating an ad that looks legitimate, for a popular product or service. However, instead of directly purchasing ad space on authorized websites, they exploit vulnerabilities in ad networks or use deceptive tactics to infiltrate the ad ecosystem.

For instance, they might disguise malicious code within the ad creative itself, such as within an image or JavaScript file. Alternatively, they could compromise a third-party ad network or ad exchange platform, injecting malicious code into the ad-serving process. Once the compromised ad is served to a website, it appears to be a genuine advertisement.

The real trouble comes when a user clicks on a compromised ad or visits a website hosting malicious ads, because the malware embedded within it is triggered, initiating a chain reaction of nefarious activities. This can range from installing ransomware or spyware on the user's device to redirecting them to phishing websites designed to steal sensitive information like login credentials or financial data. Scary, right? 

Moreover, malvertising doesn't discriminate based on device or platform. Whether you're browsing on a desktop computer, laptop, smartphone, or tablet, you're equally susceptible to encountering malicious ads. Cybercriminals capitalize on flaws in ad networks and are experts in exploiting weaknesses in ad-serving algorithms to maximize their reach and impact. 

How does it affect Users and Brands? 

The repercussions of malvertising are twofold, affecting both users and brands alike.

For users, encountering malicious ads can lead to various issues, ranging from identity theft and financial loss to system compromise and data breaches. 

Imagine you're browsing your favorite news website on your smartphone. As you scroll through the articles, you come across an eye-catching banner ad promoting a limited-time offer for a product you really want. Intrigued, you click on the ad to learn more... But this apparently innocent ad has been compromised. 

Upon clicking on the ad, the malware may begin by silently downloading and installing ransomware or spyware onto your device. 

  • Ransomware is a type of malware that encrypts your files and demands payment for their release.
  • Spyware secretly collects sensitive information from your device, such as login credentials and financial data. 

Simultaneously, the malvertising campaign may redirect you to a phishing website designed to mimic a legitimate login page for a popular online service, such as your bank or email provider. Thinking you're logging into your account, you unwittingly enter your username and password, unknowingly providing cybercriminals with access to your sensitive account information.

These attacks not only erode trust in online advertising but also undermine the overall user experience, driving users away from affected platforms and websites. 

On the other hand, brands bear the brunt of malvertising in terms of reputational damage and financial losses. When their ads accidently serve as conduits for malware distribution, brands risk tarnishing their image and losing the trust of their customer base. Users often blame the brand for lacking security measures and taking action against these threats. 

Additionally, the costs associated with mitigating the fallout from a malvertising incident, including legal fees, PR efforts, and compensation for affected users, can be substantial.
