Super Pumped: The Battle for Uber by Mike Isaac:
Pham’s fraud specialists soon proved invaluable—and not just in China. In Brooklyn, the team watched as credit card thieves used stolen card numbers to run drug trafficking and prostitution rings using Uber vehicles. The ruse was simple: the dealers would buy stolen credit card numbers from the Dark Web, then plug those number into the app to charge Uber trips to the stolen accounts. Over hundreds of trips per week they delivered drugs and call girls throughout New York City—all paid by Uber incentives, or through chargebacks from credit card companies after the original card owners reported the fraud.
After monitoring the criminals for months, Uber eventually partnered with the New York Police Department to help take the scammers down in a complicated sting operation. Over the court of a single Uber ride, the police would obtain a report from a credit card company, call the driver of the vehicle and tell them to pull over, then arrest the rider on a number of charges, including credit card fraud, possession of narcotics, prostitution, and so on. Though they would never brag about it publicly, the fraud team helped the NYPD take out the entire operation.
