Earlier this year, a careless employee at an investment firm learned a painful lesson: Sharing files through peer-to-peer Web sites like LimeWire can easily expose internal data in a corporate network. In this case, the employee worked for Washington-based Wagner Resource Group, which counts several politically connected people, including U.S. Supreme Court Justice Stephen Breyer, among its clients. The employee's actions revealed the personal data of Breyer and the firm's 2,000 or so other clients -- and the breach was not discovered for some six months.
