The personal data of users of LiteBit, a cryptocurrency exchange, may be on the street.
The Dutch company reported this in an email to customers on Wednesday.
This concerns personal data of Dutch users provided before December 2019.
According to the company, no passwords, ID documents or funds have been stolen.
LiteBit recently received a message stating that personal data of users of the platform is in the hands of third parties.
"There is a threat to disclose this personal data if LiteBit would not pay for this data," the company writes in the email.
However, LiteBit did not agree.
"Our position is that we do not want to contribute in any way to maintaining this type of criminal activity. Paying for data is not in line with our policy."
The company has reported the incident to the police and informed the Dutch Data Protection Authority (AP).
A team of experts is investigating the matter.
LiteBit was not available for a response to NU.nl.
