In November 2008, the major pharmacy benefit management firm said it received an anonymous letter that included the names, Social Security numbers, birth dates and, in some cases, prescription information of 75 members. The writer or writers threatened to release millions of more records if the business failed to pay an unspecified sum of money.

In the last two months, based on new information from the extortionists, Express Scripts began notifying more than 700,000 victims of their personal information may have been compromised.

After initially notifying only the 75 victims from last year, the company in August was told by the FBI that “…the perpetrator of the earlier action had recently forwarded a letter and data file to a law firm,” according to the company's website.

Maria Palumbo, spokeswoman for Express Scripts, would not elaborate on the contents of the letter.

“The FBI is conducting the investigation that was opened last fall,” she told SCMagazineUS.com Thursday. “It is still ongoing.”

The website points out, however, that FBI special agents contacted Express Scripts immediately, and the news was not good.
