Are Your Digital Ad Campaigns Safe from Sophisticated Bots?

The digital world is evolving rapidly, and marketers are moving from traditional platforms to digital platforms. But in this growing digital ecosystem, someone is hiding behind the screens to disrupt your growth.

Behind all the pros of digital advertising, a manipulated truth is that marketers are unaware of who is coming to see their ad campaigns.

To throw light on this, ad fraud solution providers have come into the limelight to validate how much invalid traffic is coming to the ad campaigns.

However, just when the marketers were ready to combat ad fraud, cybercriminals expanded their fraud zone with sophisticated bots. Unlike the general bots, the sophisticated bots can replicate human behavior and hide easily behind the cloak of genuine traffic resulting in manipulated data. This again makes the marketer’s ad campaigns vulnerable to ad fraud.

What is the solution? 

Advanced Problems Need Advanced Solutions

Once a sophisticated bot penetrates your digital ad campaign, it will not just impact one KPI but also manipulate your entire sales funnel and manipulate the data. For example, if you’re running an impressions campaign then first it will inflate the number of impressions with bot traffic. And once that is done, they will impact your hard KPIs like lead, conversion, or install.

The result is that you not only waste your ad spend on invalid traffic but also open the gateway to your brand assets for the sophisticated bot army to attack and destroy.

Thus, it is important to get a full-funnel ad fraud detection tool instead of a solution that covers just one KPI.

Know in detail about the different types of sophisticated bots that are hard to detect on the web and app. And for the advanced solution, stick with us till the end of this blog.

Sophisticated Web Fraud Techniques That Are Hard to Detect

Imperceptible Window

To improve the CTR of the site, the  fraudsters open the advertiser’s landing page to a zero-sized pixel. However, the end-user is unaware of this and when they visit the website it is registered as a click in google ads platform. The advertiser ends up paying for these clicks/visits which were not even seen by the user.

Example of Page View Fraud

Digital Ad CampaignIn the above case, the user didn’t click on the advertisement, but a click has been registered. As the window size is imperceptible for the user, they are unaware of this case. Generally, it is difficult to detect these anomalies without the help of advanced data analytics capabilities.

Cookie Stuffing

Cookie stuffing is organic theft where a website drops one or more third-party cookies onto a user’s web browser. An Iframe of ‘0x0’ pixel is used to dropping a cookie to hijack the organic user. These malicious cookies thus incorrectly attribute the organic traffic to the fraudulent affiliate.

Digital Ad CampaignIn the above example, we have incorporated a mFilterIt pixel which drops a randomly generated cookie whenever a user visits the advertiser’s website for the first time. Upon the return of that user, the same cookie value indicates the return of the same user. We also observed that despite faking or rotating the IP, the bot device is returning the same cookie within a gap of a few minutes.

Bot User

Fake users or Bot emulated users usually don’t have any mouse movement or touch interactions. They are also programmed in a way where they don’t react to the advertiser’s landing page. In this case, where there is no user interaction, we use the capabilities of Machine learning algorithms combined with captured values like configurations, plugins, device settings, canvas fingerprinting, etc.

This helps to analyze the bot patterns and cases where the clicks bots are happening at a high probability.

With the help of AI, ML, and data science, we detected approximately 32k such cases just in the pilot phase.

Sophisticated App Fraud Techniques That Are Hard to Detect

Click Spam

Click spamming starts when a user downloads an infected app on their device – or visits an infected mobile website. These infected apps are usually downloaded outside the walled gardens of the Play Store and IOS app store.

The infected app has built-in code which is programmed to create clicks on ads or allow external devices to click within the app. The app works normally on the user’s device, except for the tiny code running click-spam activities in the background. This fraud technique generates click spamming from the user’s device without their knowledge. And the advertisers are under an impression that the clicks are generated by real users.

Example of Click Spam

Digital Ad Campaign

In this case, clicks and installs are high whereas the conversion rate is as low as 0.01%. This is a clear case of click spamming. These clicks were generated in a time period of 9 days from Thailand. Surprisingly, the total clicks are equivalent to the population of the country. This kind of CTIT curve is often overlooked by the attribution platforms due to the clicks being refreshed in the background. At mFilterIt, we track the click patterns in case of click generating from the same device ID.

Event Spoofing

Event spoofing is one of the advanced fraud techniques used by fraudsters to manipulate the install data of advertisers. In this case, the fraudsters programmed bots that can fire fake clicks in the background to capture the events. This eventually leads to an event being spoofed and attributed without a legitimate install.

This results in the advertiser believing that a legitimate install happened. However, in reality, no event has occurred. The events like bookings, purchases, signup, registration, etc. are required to be analyzed thoroughly to identify in-app fraud.

Example of Event Spoofing

In this case, the CTIT is distributed within a few minutes, which is unusual. The normal traffic pattern is spread over as the conversion time is usually not in the control of the publisher.
