In December 2016, an employee login site was hacked and exposed, forcing Promedia, the world’s largest retailer, to suspend its payroll system and pay a $15 million fine.
The breach of the Promedias security system led to a compromise of customer data, including Social Security numbers and credit card numbers.
The data was stored in the company’s internal systems.
The company reported that it did not have a way to verify that the breach had occurred.
The employee login system was compromised by a “virus-infected botnet” that had gained access to user accounts and access to data stored in Promediacs data center, according to the company.
Promedia did not immediately respond to CNBC’s request for comment.
In March 2018, Promedicom, a major player in the home healthcare industry, announced it would begin paying employees via an employee security card to access their health information.
A year later, it started charging a fee for the service, and the service now costs $5.
Promedis customers can login through the website, but the company said it would not use the credit card information of customers who do not pay for the membership.
