Yahoo confirmed Thursday that hackers broke into the company’s network and stole the login information of about 450,000 individuals who use Yahoo and other popular Internet e-mail services, including Google Inc.’s Gmail, AOL, Verizon.net, and MSN.

The hacker group, which calls itself D33D, broke into a list of the e-mail addresses and passwords of people signed up for the Yahoo Contributor Network, a place for budding writers, photographers, and videographers to publish their work on the Internet. Because users can opt to use an outside e-mail address to join the network, the stolen information included user names and passwords for accounts on a number of e-mail services.
