Ad Injection Mitigation

Stop your website from generating revenue for criminals while protecting your brand from being associated with malicious or illicit messaging

There are many ways in which ads can be injected into your website, displaying everything from competitive content to illicit or political material. It is estimated that up to a quarter of online visits are being affected by ad injection today. 

Most client-side website security solutions cannot solve ad injection because they have no ability to control content being injected after the page loads – Ensighten can. Our technology utilizes real-time network filtering which blocks the loading of remote contentwhether it is injected through a breach or simply through a rogue browser extension.

What is ad injection?

Ad injection is the process of injecting unauthorized ads into a website where the entity injecting them has no business relationship. For example, a malicious actor could target a retailer by injecting competitive ads which display cheaper prices or even alternate models. Another malicious approach could involve an advertisement directing a user to an unknown, sinister website, where they would automatically and unknowingly download adware onto their device or input payment details which end up in the wrong hands to be sold on the dark web for profit.

Injecting ads into web pages can be achieved through various ways, such as utilizing rogue browser plugins and extensions and deceiving users into installing them. Websites can also have ad injection code directly inserted through an infrastructure breach, a site vulnerability such as cross-site scripting (XSS) or by tampering with one of the third-party libraries used within the web pages. 

Protect online revenue 

For organizations that generate revenue from displaying ads, the effects of injection go beyond simple competitive content to stealing revenue. Some ad injection-based attacks will actively replace legitimate ads with ones that generate revenue for the attackers instead. While organizations invest resources into preventing ad blockers, they often overlook that the very same techniques can be used to inject alternate ads too. 

This is a problem which often goes unnoticed by website owners – and with your website visitors potentially being directed to other end destinations out of your control, your online revenue will ultimately suffer.

Not knowing is a big part of the problem

One of the biggest problems with ad injection is that organizations do not know that it is happening. Ads are usually injected after the web page has loaded and as such, shows no activity in web server logs or the like. 

With injected ads being used to present everything from political messages to competing or even illegal products, unsuspecting users who have simply installed a rogue extension will associate such content with your website and brand. If you are not aware that this is happening, then it is very hard to address the problem. 

Preventing ad injection 

You cannot prevent the injection of code into your website client side – this is the very premise on which browser extensions are built. You can, however, prevent any injected code from being able to load dynamic content from the Internet, such as ads or malicious data skimming code. 

The only solution to mitigating ad injection is to prevent the ability for your website to display content from network locations other than those which you explicitly approve by implementing a whitelist of trusted and validated network locations.
