CBS Los Angeles reports that the Los Angeles Gay & Lesbian Center recently began notifying about 59,000 current and former clients that their personal information may have been compromised between around September 17, 2013 and November 8, 2013.

"Specifically, upon learning of the potential of this incident, we promptly took the following actions: (i) curtailed the intrusion; (ii) hired numerous experts, including two leading national forensic investigation firms, to help us investigate the situation and determine the individuals and information potentially affected; and (iii) began the process of notifying potentially affected individuals," Center privacy officer George Gati wrote in the notification letter [PDF].

While there's no indication that any information was actually stolen, the data potentially exposed includes names, contact information, credit card information, medical or health care information, Social Security numbers, birthdates and health insurance account numbers.

"The Center takes the privacy of our clients very seriously," Center CEO Lorri L. Jean said in a statement. "After learning of this attack, we took immediate steps to further safeguard the information currently on our servers and, though no organization can ever be assured that its data is 100 percent protected, we are working with data security and technology experts to guard against future attacks."

All those affected are being offered a free year of identity protection services through Experian's ProtectMyID Alert.
