MacKeeper researchers recently discovered more than 400 GB of publicly accessible data online with no password protection, linked to the printing and design company PIP Printing and Marketing Services. The data includes credit card numbers, billing information, and scanned documents relating to medical records, court cases, leading companies and celebrities -- including former NFL players' Social Security numbers and medical information, papers related to lawsuits against Hollywood studios, and thousands of confidential files from Hustler Hollywood stores. The researchers first discovered the data in October 2016. They tried to notify PIP Printing by email and phone, but received no response. Michael Bluestein, PIP's owner, told NBC News that the breach occurred when a third-party IT firm accidentally misconfigured its backup protocols. "We acted quickly to lock down access to our database and further secure our server and encryption," PIP stated.
