Uber Technologies Inc.’s former security chief was convicted of concealing a massive data breach in a case that prosecutors tied to the company’s troubled past under its original leadership.
Joe Sullivan was found guilty in San Francisco federal court Wednesday by a jury which rejected his claim that other executives at the ride-hailing giant were aware of the 2016 hack and were responsible for it not being disclosed to regulators for more than a year.
The trial featured almost four weeks of testimony that explored cyber security management as well as a shakeup at Uber in 2017 when a series of scandals drove co-founder Travis Kalanick out as chief executive officer.
Sullivan was convicted of both charges against him, obstructing a government investigation and concealing the theft of personal data of 50 million customers and 7 million drivers.
Sullivan, a former federal prosecutor who previously headed security for Facebook, is well-known for his expertise in the field in Silicon Valley. He faces as long as eight years in prison, though his sentence will likely be far less.

Companies are required under state and federal laws to promptly disclose data breaches. Uber’s mishandling of the 2016 attack on its servers resulted in the company paying $148 million in a settlement with all 50 states, which at the time was the biggest data-breach payout in US history. Uber had previously been reprimanded by the Federal Trade Commission over a similar data breach from 2014.
Sullivan was accused of actively covering up the hack. Prosecutors alleged that he quietly arranged for the company to pay the hackers $100,000 in Bitcoin to delete the stolen data under the guise of a program used to reward security researchers for identifying vulnerabilities, known as a “bug bounty.” In return, the two hackers agreed not to disclose that they had stolen the data. The hackers later pleaded guilty for their role in the incident.
The October 2016 hack stayed secret until the following November when it was disclosed by the new CEO, Dara Khosrowshahi, about three months into his tenure. At the same time, he fired Sullivan.
Khosrowshahi testified that after discovering inconsistencies in Sullivan’s account of what happened, he decided it was time to replace his security chief. “I couldn’t trust his judgment anymore,” he said.
Sullivan’s defense was that Uber’s legal department and other managers were aware of the incident before it blew up publicly.
David Angeli, Sullivan’s lawyer, challenged the notion of a coverup by pointing to his sharing of information with numerous employees, before Khosrowshahi arrived at the company. Jurors were shown a 1:24 a.m. text that Sullivan sent to Kalanick describing the breach less than 12 hours after it happened.
“Remember, Mr. Kalanick is the top person at Uber,” Angeli said at closing arguments. “Mr. Sullivan could not have reported this to someone higher up at the company.”
Prosecutors argued that Sullivan, who joined Uber in 2015, was well aware of the requirements to disclose the breach, especially after the company’s dealings with the FTC over the 2014 hack.
Sullivan, who was supposed to have improved security after the earlier breach, didn’t want the details of the new hack to get out because it would have hurt his reputation, prosecutor Ben Kingsley told jurors.
Rather than disclose it, Sullivan “prioritized his reputation, and the company’s reputation, over his obligations,” he said.
Sullivan didn’t testify, nor did Kalanick.
