Over the past few years, Uber has schemed to boost its self-driving efforts by spying on rivals, poaching staff, and acquiring their software, according to newly released court documents. Though competitor intelligence work is standard among large companies, the details are rarely made public.

In the long-running Waymo v. Uber lawsuit, Uber stands accused of stealing and using trade secrets from Alphabet’s self-driving car division to boost its own, younger program. New documents filed in federal court this week focus on the activities of Uber’s Strategic Services Group (SSG), an eight-person group within the company’s Threat Operation division, dedicated to collecting intelligence on competitors. A former ThreatOps employee has claimed that SSG frequently engaged in fraud and theft, and employed third-party vendors to obtain unauthorized data or information.

Uber denies these allegations, arguing that they were part of that employee’s attempt to extort money from the company amidst the Waymo lawsuit. But it made SSG staff available for deposition by Waymo in December. These depositions detail the group’s activities, including video surveillance of rivals’ cars, talking with suppliers, plans to acquire self-driving software by scraping websites, and a trip to Las Vegas for the CES trade show.

The group’s efforts included launching a project called Zoo to learn more about Uber’s self-driving rivals, each of which got its own code name. “SSG’s 2017 research will focus on Giraffe, Turtle, Zebra and Turtle/Chimp as well as competitors from Asia,” said a planning document SSG staff wrote in December 2016, which a lawyer for Waymo read into the court record.

Giraffe was Uber’s code-name for Google and Waymo, court records indicate. Turtle/Chimp could refer to General Motors and either Lyft (with which it wants to build a self-driving car network) or Cruise, the startup GM bought in 2016. Zebra—whose goal is quoted as being to “reinvent completely the automobile”—might be Zoox, a stealthy Silicon Valley startup that is building a robotic taxi from the ground up.

“Giraffe leads the other 30-plus companies in the race to field fully autonomous vehicles,” admitted the report. “For 2017, SSG’s priority effort will be Giraffe.” SSG was interested in which automakers Waymo was working with, what technology needs it was outsourcing, and who its suppliers were, the records reveal. SSG was also tasked with “[tracking] social media accounts, e.g., LinkedIn, Facebook, Twitter, et cetera, in order to map the personal and professional networks of key personnel” at Waymo.

The group’s prime target was the stuff that makes Waymo’s cars so smart: their secret source code. “Success in [the] autonomous vehicle race ultimately hinges on the source code,” read another SSG document. “All the source code necessary for success can be compressed to [around] 75 megabytes.” In comparison, an hour-long Netflix download is about 200 megabytes.

SSG started its search by examining GitHub, a website where software developers post all kinds of open source software. “We would [be] looking for context that would be… inadvertently dropped out of there by an engineer [but] we’ve never run across anything that I would consider protected data,” Matt Henley, Uber’s director of ThreatOps, said in a deposition.

The next plan, court records show, involved sending SSG staff to CES in January 2017—autonomous driving is a major topic at the enormous technology trade show in Las Vegas. Team members attended technical presentations to see if they could glean any information about other companies’ source code that would help Uber’s Advanced Technology Group build its own robocars. Unsurprisingly, that didn’t work either, probably because most companies avoid revealing key technical data in public lectures.
