According to reports, the ride-sharing company had been hacked.
The company said in a statement that it was responding to a cyber incident. Additional updates will be posted here as they become available.
According to the New York Times, a hacker gained control of the internal systems of the ride-sharing company after compromising the account of a worker. Tech companies and startup use a workplace messaging service called slack.
Multiple reports say that the ride-sharing company has disabled its chat service. The company's shares declined in pre market trading.
The hacker gained access to other internal databases after compromising the internal messaging service.
The Washington Post reported that the alleged attacker told them that they could leak the company's source code within months.
The Post reported that two people familiar with the matter said that employees initially thought the attack was a joke and responded to the alleged hacker with a variety of images.
The hacker is said to have gained access to internal financial data, as well as taking over the accounts of Amazon Web Services and the company.
CNBC couldn't verify the information. The statement was posted on the social networking site.
Initial reports show that the hacker used social engineering in order to compromise the systems of the ride hailing company. Criminals prey on people's inexperience and credulity to get into corporate accounts.
Ian McShane is the vice president of strategy at the firm. It looks like the attacker did it forulz, given the access they claimed to have.
The human is the weakest link in your security defenses.
Joe Sullivan, the former security chief for the ride-sharing company, is currently on trial for his role in the 2016 hack. The company settled with 50 states and Washington, D.C. after admitting to concealing the attack.
In the wake of the departure of Kalanick, the company has tried to clean up its image. Scandals from Kalanick's tenure are still haunting the firm.
In July, The Guardian reported on the leak of thousands of documents which showed how the company pushed into cities even if it meant violating local laws. Kalanick said that "violence guarantees success" after being confronted by other executives about concerns for the safety of drivers sent to a protest in France.
The events reported by The Guardian were not in line with the values of the company.
