Many of the names and some of the information in Jacobs' letter have been redacted. Jacobs' legal team persuaded Alsup to allow those deletions to protect the identities of former CIA agents that worked with Uber's espionage team, a since disbanded unit called Marketplace Analytics. The letter alleges that two Uber security executives, Joe Sullivan and Craig Clark, played central roles in putting together the company's clandestine operations. Marketplace Analytics allegedly targeted overseas rivals and Waymo in the U.S. while creating a network of secret communications channels and alternate devices designed to cover their digital tracks and avoid legal trouble. Uber fired both Sullivan and Clark for paying $100,000 to two hackers who stole the personal information of drivers and passengers — and then covering up the theft. Uber itself tried to hack into its rivals' computer networks in an effort to scoop up valuable information, Jacobs' letter alleges.
