Employee theft of company data may be motivated by a desire to monetize that data, to embarrass or retaliate against an employer, or by simple ignorance. For example, a Tufts Health Plan employee recently pled guilty to data theft after stealing customer information for more than 8,000 Tufts customers in a scheme to collect fraudulent Social Security benefits and tax refunds. In another recent case, a disgruntled employee of Morrison's, a large UK supermarket chain, stole payroll information for thousands of the company's employees and posted it online as a "concerned Morrisons shopper," in addition to mailing copies to local newspapers. Finally, in one of the largest of the recent employee data theft cases, a Morgan Stanley financial advisor apparently obtained data from 350,000 Morgan Stanley clients by running internal reports on data he was not authorized to access.
