Researchers from German security firm Kromtech Security allege that until recently, MBM Company was improperly handling customer details. On February 6, they identified an unsecured Amazon S3 storage bucket, containing a MSSQL database backup file.

According to Kromtech Security’s head of communications, Bob Diachenko, further analysis of the file revealed it held the personal information for over 1.3 million people. This includes addresses, zip-codes, e-mail addresses, and IP addresses. He also claims the database contained plaintext passwords — which is a big security ‘no-no.’

In a press release, Diachenko said: “Passwords were stored in the plain text, which is great negligence [sic], taking into account the problem with many users re-using passwords for multiple accounts, including email accounts.”

The backup file was named ‘MBMWEB_backup_2018_01_13_003008_2864410.bak,’ which suggests the file was created on January 13, 2018. It’s believed to contain current information about the company’s customers. Records held in the database have dates reaching as far back as 2000. The latest records are from the start of this year.

Other records held in the database include internal mailing lists, promo-codes, and item orders, which leads Kromtech to believe that this could be the primary customer database for the company.
