While Evernote says that no content or payment information was accessed, hackers did acquire usernames, email addresses, and encrypted passwords.
In our security investigation, we have found no evidence that any of the content you store in Evernote was accessed, changed or lost. We also have no evidence that any payment information for Evernote Premium or Evernote Business customers was accessed.All Evernote users will be prompted to choose a new password when logging in to the website. The company is is also releasing updates to several of its apps today to facilitate the password change.
The investigation has shown, however, that the individual(s) responsible were able to gain access to Evernote user information, which includes usernames, email addresses associated with Evernote accounts and encrypted passwords. Even though this information was accessed, the passwords stored by Evernote are protected by one-way encryption. (In technical terms, they are hashed and salted.)
Evernote's security breach comes a bit over a week after Apple, Twitter, and Facebook were hacked when employees visited iPhoneDevSDK, an online forum for software developers.
