Evernote Compromised, But Says No User Data Affected

by in , , , , , 0

On Saturday 3/2/2013, Evernote, the online service that enables users to store and sync all kinds of data across multiple devices, sent out a notice to their users stating that their Operations & Security team had  discovered and blocked suspicious activity on the Evernote network that appeared to have been a coordinated attempt to access secure areas of the Evernote Service.


Evernote officials said that they did not think the attackers were able to gain access to any of the data that users store on the service. However, the company said it was requiring that all users change their passwords immediately.

Evernote users have the ability to store just about any kind of data on the service, including text, video and other information. Users can encrypt data within specific notes, and the company doesn't have a copy of users' keys, so if the passphrase is lost or compromised, there's no way for the company to recover that data.

Evernote sent all of its users an email detailing the incident and informing them that they need to change their passwords before logging in the next time (see below).

Dear Evernote user,

Evernote's Operations & Security team has discovered and blocked suspicious activity on the Evernote network that appears to have been a coordinated attempt to access secure areas of the Evernote Service.

As a precaution to protect your data, we have decided to implement a password reset. Please read below for details and instructions.

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.

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.)

While our password encryption measures are robust, we are taking steps to ensure your personal data remains secure. This means that in an abundance of caution, we are requiring all users to reset their Evernote account passwords. Please create a new password by signing into your account on evernote.com.

After signing in, you will be prompted to enter your new password. Once you have reset your password on evernote.com, you will need to enter this new password in other Evernote apps that you use. We are also releasing updates to several of our apps to make the password change process easier, so please check for updates over the next several hours.

As recent events with other large services have demonstrated, this type of activity is becoming more common. We take our responsibility to keep your data safe very seriously, and we’re constantly enhancing the security of our service infrastructure to protect Evernote and your content.

There are also several important steps that you can take to ensure that your data on any site, including Evernote, is secure:
Avoid using simple passwords based on dictionary words
Never use the same password on multiple sites or services
Never click on 'reset password' requests in emails - instead go directly to the service

Thank you for taking the time to read this. We apologize for the annoyance of having to change your password, but, ultimately, we believe this simple step will result in a more secure Evernote experience. If you have any questions, please do not hesitate to contact Evernote Support.

The Evernote Team
