Kromtech Security has reported that the sensitive personal information of more than 25,000 investors of Bezop cryptocurrency was exposed when a MongoDB database was left unsecured. The security incident is reported to be linked to a distributed-denial-of-service attack that occurred earlier this year.

The investors’ compromised information included their names, addresses, email addresses, photocopies of their driver’s licenses and passports, wallet information, encrypted passwords and other IDs.

Although the investors were notified in January of the incident, the data was reportedly accessible through March 30.
