The Washington Post: Hackers associated with the group D33D Company have posted online the usernames and passwords for 435,000 Yahoo Voice accounts. Formerly known as Associated Content, Yahoo Voice is a crowd-sourced content publishing service.
Security firm TrustedSec said that the passwords appear to have been stored as plain text, without any encryption. An analysis of the passwords reveal that many are particularly weak, with "123456" being the most common password chosen. Some observers believe the passwords may be from an old list, as many of the username password combinations appear not to work.
