The hacker had alerted Curry and other security researchers to the intrusion by using an internal Uber account to comment on vulnerabilities they had previously identified on the company's network through its bug-bounty program, which pays ethical hackers to identify vulnerabilities.
The hacker provided a Telegram account address and Curry and other researchers then engaged them in a separate conversation, sharing screenshots of various pages from Uber's cloud providers to prove they broke in.
The Associated Press attempted to contact the hacker at the Telegram account where Curry and the other researchers chatted with them. But no one responded.
One screenshot posted on Twitter and confirmed by researchers shows a chat with the hacker in which they say they obtained the credentials of an administrative user and then used social engineering to access Uber's internal network.
Uber said via email that it was "currently responding to a cybersecurity incident. We are in touch with law enforcement." It said it would provide updates on its Uber Comms Twitter feed.
