Scribd has announced that it suffered a minor hack earlier this week. The hack seems to have targeted just user login information, meaning only e-mails and passwords were at risk. Scribd adds that they believe less than 1 percent of users were affected by the attack and that they have contacted every account asking them to reset their password.
Because of the way Scribd securely stores passwords, we believe that the passwords of less than 1% of our users were potentially compromised by this attack...We have now emailed every user whose password was potentially compromised with details of the situation and instructions for resetting their password...Our investigation indicates that no content, payment and sales-related data, or other information were accessed or compromised. We believe the information accessed was limited to general user information, which includes usernames, emails, and encrypted passwords.
If you didn't receive an e-mail, you're probably not affected. If you're still concerned, Scribd has set up a website to allow you to check if your account was one of the affected accounts.
