Ernst & Young has lost another laptop containing the social security numbers and other personal information of its clients' employees. This time, the incident puts thousands of IBM workers at risk.

The laptop was stolen from an Ernst & Young employee's car in January. The employee handled some of the tax functions Ernst & Young does for IBM's workers who have been stationed overseas at one time or another during their careers. As a result of the theft, the names, dates of birth, genders, family sizes, SSNs and tax identifiers for IBM employees have been exposed.
