DoubleVerify takes down Ad Impression Fraud Scheme in Audio

DV Exposes ‘BeatSting,’ a scheme generating fake audio ad traffic at scale through large audio platforms.

DoubleVerify, a leading software platform for digital media measurement, data and analytics, today announced the discovery of “BeatSting,” the first large-scale ad impression fraud scheme to target audio inventory. Since the DV Fraud Lab first identified the family of fraud in 2019, an estimated $20 million has been siphoned from advertisers. BeatSting alone is responsible for costing unprotected advertisers up to $1 million per month.

BeatSting is part of a bigger family of server-side ad insertion (SSAI) fraud schemes that emerged in 2019 and initially targeted connected TV (CTV) inventory. In this specific iteration, fraudsters begin by spoofing residential IP addresses and audio apps. At the same time, they also set up fake SSAI servers to falsify audio ad requests, making the inventory attractive to advertisers. If an advertiser bids on this inventory and wins the bid, their ad dollars are wasted on a fraudulent opportunity. And by creating fraudulent inventory, the fraudsters are also siphoning money away from legitimate audio channels.

“Fraud always follows the money, and increasingly that money is flowing to digital audio, a rapidly emerging channel where digital advertising standards are still evolving,” added Mark Zagorski, Chief Executive Officer at DoubleVerify. “CTV continues to experience this phenomenon and, increasingly, audio is quietly becoming a new channel of interest and attack.”

‘The number of audio channels has increased exponentially, accompanied by an increase in advertising. With this surge, however, comes a new wave of fraud. Given that the size of the digital audio market in India is expected to grow multifold in the coming years, advertisers will need to be familiar with cutting-edge ad fraud techniques in order to mitigate risk and protect the integrity of their campaigns,” said Nachiket Deole, DoubleVerify's Head of Sales in India.

The DV Fraud Lab detected a dramatic increase in fraudulent activity targeting audio channels after initially noticing smaller instances of this attack in 2021. This is the first time a fraud scheme has generated fake audio traffic at scale through large audio platforms.

DV’s Fraud Lab — powered by a dedicated team of data scientists, mathematicians and analysts — performs ongoing detection and analysis of new types of digital ad fraud in order to uncover the latest schemes as they occur. Through continuous analysis, scenario management and research, the Fraud Lab pinpoints the sites, apps and devices responsible for fraudulent activity and updates protection for DV clients in real-time.
