COPENHAGEN Reuters -- Personal data stolen from wind turbine maker Vestas by hackers in a so-called ransomware attack last month has been made public, the firm said late on Wednesday.
A Nov. 19 cyber security incident forced Vestas to shut down IT systems across multiple business units and locations to contain the issue.
The Danish company said it was able to continue operations but that data had been compromised.
The hackers managed to retrieve data from the compromised internal file share systems, and have made some of the compromised data public, Vestas said in a statement.
It said that the majority of compromised data includes personal information, such as names, contact details and CVs, as well as some cases of more sensitive information, such as social security numbers and bank account information.
It said that all employees and business partners should be alert to any indications of misuse of their personal data because of the potential risk caused by the leak of personal data.
Ransomware has dominated cybersecurity threats this year, encrypting victims' data and can include locking down an organisation's network or stealing data.
The victim will get a key in return for payments that can run into hundreds of thousands or even millions of dollars in the event of a hack.
