Malvertising: Definition, Detection, Affect, and Prevention

The Definition of Malvertising

Malvertising, also known as malicious advertising, refers to the practice of using online advertisements to distribute malware or redirect users to dangerous websites. Malware is any type of software that can damage your computer or device, including viruses, ransomware, spyware, trojans, and more. Malvertising can compromise your device without your awareness or agreement, jeopardizing your privacy, security, and performance.

The deceptive aspect of malvertising lies in its capability to operate without triggering any warnings or indications that users’ systems are at risk, making it a stealthy and effective method for cybercriminals.

Malvertising vs. Ad Malware

Malvertising is often confused with ad malware or adware:

• Adware is a type of application that generates unwanted advertisements, often causing annoying pop-ups on users’ devices. It can be bundled with legitimate apps or installed without the user’s knowledge, leading to ads, rerouted searches, and the collection of personal information for targeted advertising.
• Malvertising involves harmful code placed on a publisher’s webpage, targeting users who visit that page.

When comparing malvertising and ad malware, it is crucial to recognize the clear differences:

• Malvertising involves the implementation of harmful code on a publisher’s webpage, specifically aimed at individual users. In contrast, adware targets individual users without initially being placed on a publisher’s webpage.
• Additionally, malvertising affects only those users who visit an infected webpage, while adware, once installed, remains active continuously on a user’s device.

To sum up, malvertising and ad malware are different in their methods and effects. Malvertising relies on compromised webpages, while adware consistently operates on a user’s device. Thus, it is also necessary to remove adware from your computer. The following is about how to remove adware from Windows.

Malvertising Detection

Here are some typical signs of identifying advertisements that may have malvertising:

1. Grammatical Errors: Mistakes in spelling or grammar reflect a lack of professionalism.
2. Overpromising: Be wary of the deals that appear excessively favorable, which are frequently scams.
3. Poor-Quality Images: Unclear photos may indicate a lack of reliability. Usually, authentic ads are generally well-crafted.
4. Surprising Pop-Ups: Advertisements that unexpectedly appear with urgent calls to action could be malvertising.
5. Irrelevant Advertisements: Ads that do not relate to your interests or previous searches might be fraudulent.
6. Suspicious Web Addresses: Verify if the link looks unusual. If it is, it could direct you to unsafe websites.

How Malvertising Works

Malvertising works by tricking site owners or advertising networks into displaying fraudulent ads on their platforms. Criminals can achieve this in two primary ways:

• Exploiting advertising networks: Cybercriminals can take advantage of ad distribution platforms to target numerous sites simultaneously.
• Deceiving website owners: Criminals may directly contact website owners, masquerading as legitimate advertisers to have an ad published.

The reason why criminals favor networks is due to their scale, which allows for greater visibility and engagement with their deceptive advertisements.

After the advertisement goes live, the criminal waits for visitors to the website to either:

• View the advertisement: Users will automatically install malware onto their device just by loading the page containing the ad.
• Click on the advertisement: Clicking may redirect users to malicious websites or prompt the download of harmful files.

Types of Malvertising Attacks

Malvertising attacks can take different ways to compromise devices or obtain data. Common types include:

• Drive-by downloads: Malvertising automatically downloads and executes malware without user consent by taking advantage of vulnerabilities in the browser or system. No click is required to trigger the attack.
• Fake alerts: These show deceptive warnings or tempting offers on users’ devices, such as notifications about malware infections or software updates. Interacting with them can result in malware installation or exposure to phishing sites designed to capture personal information.
• Clickjacking: These attacks trick users into clicking on hidden elements that overlay legitimate content. For instance, a malicious link might be concealed beneath a seemingly innocent button, directing users to harmful websites or initiating malware downloads.
