Wow. This company has records on 15% of the entire US population - and those records now appear to be in the hands of criminals.

Corporate custodians of confidential medical data should be closely monitoring events connected to a nightmarish computer security breach in the St. Louis region.

Express Scripts is one of the nation’s largest pharmacy benefits managers. The company, with headquarters in St. Louis County, handles approximately 500 million prescriptions per year for 50 million workers at 1,600 American companies. Early in October, it received an extortion letter, the details of which it released on Nov. 6.

The letter included personal information on about 75 Express Scripts clients — Social Security numbers, dates of birth and, in some cases, information about prescription medications. Whoever sent the letter demanded money from the company — the amount has not been disclosed — and threatened to use the Internet to reveal personal and medical information about millions of people if the demands were not met.

Last week, the criminal activity expanded: Express Scripts said that individual clients had received extortion letters directly.
