quotes a report from Washington Post: The Department of Justice has launched a criminal investigation into Uber's use of a secret software that was used to evade authorities in places where its ride-sharing service was banned or restricted, according to a person familiar with the government's probe. The investigation is in its early stages, but deepens the crisis for the embattled company and its chief executive and founder Travis Kalanick, who has faced a barrage of negative press this year in the wake of high-profile sexual harassment complaints, a slew of high-level executive departures, and a consequential trade secrets lawsuit from Google's parent company. The federal criminal probe, first reported by Reuters, focuses on software developed by Uber called "Greyball." The program helped the company evade officials in cities where Uber was not yet approved. The software identified and blocked rides to transportation regulators who were posing as Uber customers to prove that the company was operating illegally.
