Joint Statement From White Ops CEO and Rubicon Project President on Successful Efforts Countering Russian Ad Fraud

LOS ANGELES & NEW YORK – Rubicon Project (NYSE: RUBI), which operates one of the largest advertising marketplaces in the world, and White Ops, the leading provider of human verification services for the digital advertising market, confirmed today that Rubicon Project’s industry leading anti-fraud measures protected its buyers and sellers from the ‘Methbot’ fraud operation – one of the largest and most profitable ad fraud bot operations uncovered earlier today by White Ops. Rubicon Project’s significant investments in inventory quality protections and technology successfully kept its marketplace insulated from this serious threat, which according to White Ops, has been targeting premium programmatic video inventory, generating as much as 200-300 million non-human impressions per day.

“We can confirm that Rubicon Project’s quality and anti-fraud measures sufficiently countered this wide-ranging scheme. Rubicon Project has long been a leader in the ongoing battle against ad fraud and their commitment to this sustained fight against bad actors clearly sets them apart in the industry today.”

Michael Tiffany, CEO of White Ops, commented, “We can confirm that Rubicon Project’s quality and anti-fraud measures sufficiently countered this wide-ranging scheme.

Our longstanding commitment to fighting ad fraud in every form protected our customers from the Methbot fraudulent activities detected today. Our industry is better for the work of the White Ops team to fight ad fraud and to call on every ad tech company to commit themselves to not just talking about fraud but to taking decisive actions to counter it.
