Sometime late last year, an employee of a McLean investment firm decided to trade some music, or maybe a movie, with like-minded users of the online file-sharing network LimeWire while using a company computer. In doing so, he inadvertently opened the private files of his firm, Wagner Resource Group, to the public.
That exposed the names, dates of birth and Social Security numbers of about 2,000 of the firm’s clients, including a number of high-powered lawyers and Supreme Court Justice Stephen G. Breyer.
The breach was not discovered for nearly six months. A reader of washingtonpost.com’s Security Fix <http://blog.washingtonpost.com/securityfix/> blog found the information while searching LimeWire in June.
Services such as LimeWire, which are known as peer-to-peer networks, link computers directly, allowing users to swap digital movies, music and files with other users without the need of a central Web site to manage the exchange.
