DoubleVerify Exposes Fraud Scheme Spoofing 85M Ad Requests Daily

DoubleVerify Thursday announced the discovery of ViperBot, described by the company as “a sophisticated advertising fraud scheme that attempts to steal over $8 million each month in ad spend” across connected television (CTV) and mobile video. 

Mark Zagorski, CEO at DoubleVerify, called ViperBot "one of the most sophisticated fraud schemes" the company has identified.

DoubleVerify said its clients are protected from the scheme, but the code continues to spoof more than five million devices and up to 85 million ad requests daily. The company identified ViperBot in Q4 2021. Its peak activity occurred during the busy holiday season between Q4 2021 and Q1 2022. During this time, there were spikes.

Here’s how it works: ViperBot strips the code that verifies ad impressions from providers like Oracle, Integral Ad Science (IAS) and Pixalate, and then conceals and redirects the code through real devices to hide the fraudulent activity in an attempt to go undetected.

ViperBot relies on verification stripping, the removal of verification tags set by providers, and a new tactic, discovered by DoubleVerify called verification redirection.

Now fraudsters not only remove verification tags from the ad being delivered, but also reinsert them inside of cheap ad slots running on real devices in an attempt to prevent detection, making it difficult for measurement providers to recognize fraudulent activity.

DoubleVerify’s technology powers DV Fraud Lab, a dedicated team of data scientists, mathematicians and analysts from the cyber-fraud prevention community. The Fraud Lab relies on a variety of approaches to detect fraud, from AI and machine learning to manual review.

Last month, DoubleVerify reported that CTV fraud schemes cost publishers $144 million in 2021, identifying three schemes in late 2020 and one in early 2021 that cost publishers between $1 million and $5 million a month.

    As we have seen time and time again, the ad industry is dependent on computers and servers instead of hand placement of the ads. I understand that software driven ads are effient and lower cost in the delivery process, but hand placement of the ads is safe and secure. In the end, the bad guys will figure out how to defeat your security methods.
