Hackers Break Into Computer-Security Firm's Customer Database

Guidance Software -- the leading provider of software used to diagnose hacker break-ins -- has itself been hacked, resulting in the exposure of financial and personal data connected to thousands of law enforcement officials and network-security professionals.

Guidance alerted customers to the incident in a letter sent last week, saying it discovered on Dec. 7 that hackers had broken into a company database and made off with approximately 3,800 customer credit card numbers. The Pasadena, Calif.-based company said the incident occurred sometime in November and that it is working with the U.S. Secret Service on a more detailed investigation.
