Uber said on Friday it was responding to a cybersecurity incident after a hacker apparently breached its network.
The New York Times reported that Uber had discovered the breach on Thursday and taken several of its internal communications and engineering systems offline as it investigated the extent of the hack.
A security engineer said the intruder provided evidence of obtaining access to crucial systems at the ride-hailing service.
However, there was no indication that Uber’s fleet of vehicles or its operation was affected.
“It seems like they’ve compromised a lot of stuff,” said Sam Curry, an engineer with Yuga Labs who communicated with the hacker.
That includes complete access to the Amazon and Google-hosted cloud environments where Uber stores its source code and customer data, he said.
Curry said he spoke to several Uber employees who said they were “working to lock down everything internally” to restrict the hacker’s access. That included the San Francisco company’s Slack internal messaging network, he said.
He said there was no indication that the hacker had done any damage or was interested in anything more than publicity. “My gut feeling is that it seems like they are out to get as much attention as possible”.
The hacker had alerted Curry and other security researchers to the intrusion on Thursday evening 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 ferret out network weaknesses.
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.
The New York Times reported that the person who claimed responsibility for the hack said they gained access through social engineering: They sent a text message to an Uber worker claiming to be a company tech employee and persuaded the worker to hand over a password that gave them access to the network.
Social engineering is a popular hacking strategy, as humans tend to be the weakest link in any network. Teenagers used a similar ploy in 2020 to hack Twitter
The Times said the hacker reported being 18 years old and saying they broke in because the company had weak security. In the Slack message that announced the breach, the person also said Uber drivers should receive higher pay.
The company has been hacked before.
Its former chief security officer, Joseph Sullivan, is currently on trial on allegations he arranged to pay hackers $100,000 (€100,135) to cover up a 2016 high-tech heist in which the personal information of about 57 million customers and drivers was stolen.
