Last month, The Dental Network—a dental HMO owned by CareFirst BlueCross Blue Shield—discovered it had accidentally revealed personal data and Social Security numbers online for about 75,000 of its customers. It told the members about the screw-up three weeks later. “The company says that to its knowledge, no one has misused the information. But it says ‘the risk … should be taken seriously,'” and it’s offering affected members one year of credit monitoring. After that, as you know, the thread of identity theft plummets. Wait, what?
