Uber Technologies, the ride-hailing company, has faced a cybersecurity incident and admitted that its network was breached.
A hacker compromised an employee’s workplace messaging Slack app and used it to send a message to Uber employees announcing that it suffered a data breach, according to a New York Times report on Thursday.
It appeared that the hacker was later able to gain access to other internal systems, posting an explicit photo on an internal information page for employees.
“We are in touch with law enforcement and will post additional updates here as they become available,” Uber said in a tweet without providing further details.
The Slack system was taken offline on Thursday afternoon by Uber after employees received the message from the hacker.
“I announce I am a hacker and Uber has suffered a data breach,” the message read, and went on to list several internal databases that were claimed to be compromised.
The staff at the company was instructed to not use Slack, which is owned by Salesforce, according to the report. Other internal systems, too, were inaccessible.
