Uber Investigating Breach of Its Computer Systems

Uber discovered its computer network had been breached on Thursday, leading the company to take several of its internal communications and engineering systems offline as it investigated the extent of the hack.

The breach appeared to have compromised many of Uber’s internal systems, and a person claiming responsibility for the hack sent images of email, cloud storage and code repositories to cybersecurity researchers and The New York Times.

“They pretty much have full access to Uber,” said Sam Curry, a security engineer at Yuga Labs who corresponded with the person who claimed to be responsible for the breach. “This is a total compromise, from what it looks like.”

An Uber spokesman said the company was investigating the breach and contacting law enforcement officials.

Uber employees were instructed not to use the company’s internal messaging service, Slack, and found that other internal systems were inaccessible, said two employees, who were not authorized to speak publicly.

Shortly before the Slack system was taken offline on Thursday afternoon, Uber employees received a message that read, “I announce I am a hacker and Uber has suffered a data breach.” The message went on to list several internal databases that the hacker claimed had been compromised.
