A misconfigured AWS S3 bucket is the root cause of a data leak that impacted 2.4 million Blur users, reported the online privacy firm Abine.

Blur is a popular password manager developed by the online privacy firm Abine, it also implements private browsing features and masked email. The application was developed to secure the personal information users put online.

Last week Abine disclosed a data leak that potentially exposed personal information of Blur users. Leaked data included email addresses, password hashes ( bcrypt hashes with a unique salt for each user), IP addresses and, in some cases, first and last names and password hints.

Abine discoverd the data leak on December 13.

“On Thursday, December 13th 2018, we became aware that some information about Blur users had been potentially exposed and immediately began working to ensure our systems and data were secure, to determine what happened, and to inform and help our users.” reads the security update published by the company.

“Importantly, there is no evidence that our users’ most critical data has been exposed, and we believe it is secure. There is no evidence that the usernames and passwords stored by our users in Blur, auto-fill credit card details, Masked Emails, Masked Phone numbers, and Masked Credit Card numbers were exposed. There is no evidence that user payment information was exposed,”

According to SecurityWeek, roughly 2.4 million users were impacted by the data leak.

According to Abine, the exposed bucket was containing data related to users who had registered an account prior to January 6, 2018.

The company recommends users to change their passwords.

“As a privacy and security focused company this incident is embarrassing and frustrating. These incidents should not happen and we let our users down. We apologize and are working very hard to ensure we respond quickly and effectively to this incident and make sure we do everything we can to not let anything like it happen again,” Abine concludes.

Albine hired a security firm to help it in investigating the incident and reported it to authorities.
