Some security breaches are just caused by raw stupidity at work. For instance - look at how the Boston Globe managed to give out personal info for a bunch of subscribers:

Credit and bank card numbers of as many as 240,000 subscribers of The Boston Globe and Worcester Telegram & Gazette were inadvertently distributed with bundles of T&G newspapers on Sunday, officials of the newspapers said yesterday.

The confidential information was on the back of paper used in wrapping newspaper bundles for distribution to carriers and retailers. As many as 9,000 bundles of the T&G, wrapped in paper containing subscribers' names and their confidential information, were distributed Sunday to 2,000 retailers and 390 carriers in the Worcester area, said Alfred S. Larkin Jr., spokesman for the Globe.

In addition, routing information for personal checks of 1,100 T&G subscribers also may have been inadvertently released.

One word for these guys: Shredder.
