writes "Formspring, the Social Q&A portal focused on conversations and personal interests, admitted to being breached on Tuesday. The compromise led to the loss of 420,000 passwords, forcing the site to reset all member passwords. Mirroring the recent LinkedIn breach, Formspring said that it was alerted to a forum post that contained 420,000 password hashes. Engineers shutdown the service and confirmed the passwords were indeed theirs.
In less than a day, an investigation reveled that the attacker(s) had “broken into one of our development servers and was able to use that access to extract account information from a production database,” a blog post explains. There have been no reported incidents of individual account compromise, but there were reports of Phishing by some users on Twitter attempting to capitalize on the incident."Link to Original Source
