In the cyber attack on the automotive supplier and tire manufacturer Continental, the hackers got their hands on masses of data.
In August, the Dax group made the attack public, and now the Hanoverians admitted on Monday that data was also leaking.
The investigation of the incident with the help of external experts is still ongoing, according to a statement from Conti.
"In the meantime, this investigation has shown that the attackers were able to steal part of the data from the affected IT systems, despite established security precautions."
In August, the group announced that no data had been encrypted on its own systems and that no ransom demands had been received.
Apparently, according to information from the “Handelsblatt”, the hackers later asked for money.
According to information from the newspaper, there should be a data volume of 40 terabytes.
According to a screenshot from the Internet, which reportedly shows a chat between hackers and experts on the Continental side, no money had flowed by mid-October.
A company spokesman declined to comment on the minutes of the conversation or possible ransom negotiations.
Hackers often use two ways to get a ransom after a data attack: In many cases, they encrypt data on company computers and make them unusable until the encryption can be reversed for a ransom.
In addition, they often threaten to publish sensitive data online, as is now the case with Conti.
