Washington's UW Medicine recently announced that 90,000 patients' personal information was exposed when a UW Medicine employee opened an e-mail attachment containing malware (h/t PHIprivacy.net).

"The malware took control of the computer, which had patient data stored on it," UW Medicine said in a statement. "UW Medicine staff discovered this incident the following day and immediately took measures to prevent any further malicious activity."

While it doesn't appear that the objective was to obtain patient information, the malware apparently accessed the data files of approximately 90,000 Harborview Medical Center and University of Washington Medical Center patients, including their names, medical record numbers, other demographics (which may include addresses and phone numbers), dates of service, charge amounts for services received, birthdates, and Social Security numbers or HIC (Medicare) numbers.

The incident has been referred to the FBI, and UW Medicine says it has implemented a "review, training and outreach effort" in response to the incident, though it's not clear what that effort may include.

ID Experts is managing a call center at (877) 271-1533, where patients can call with questions.
