The following communication was sent via email to all the users whose data is involved in the leak. Keep reading after the email for more information.
“Our Security Team recently discovered and blocked suspicious activity on Cerberus
servers. The investigation found no evidence that your account was in any way accessed or compromised.
However, the attacker(s) were able to gain access to usernames and encrypted passwords for a subset of our users. No other personal data (emails, device information, etc.) has been accessed.
While the accessed passwords are encrypted, as an extra precaution we have immediately secured these accounts invalidating the current passwords.
Please create a new password by signing into your account at www.cerberusapp.com and selecting the “Forgot password?” option, or go directly here:https://www.cerberusapp.com/forgotpwd.php . Submit the form and you will receive an email with further instructions to set your new password.
After you reset the password, you can verify that no unauthorized commands have been sent to your Android device. Open Cerberus on your device, log in and select the “View Cerberus log” option at the bottom of the app settings.
We sincerely apologize for the inconvenience of having to change your password, we take security of our users very seriously and are constantly working to improve it.
If you have any questions, please do not hesitate to contact Cerberus Support at email@example.com
The Cerberus Team”
Here are some more details on the incident:
– The database was not accessed, password are hashed and uniquely salted multiple times there, and we will migrate to bcrypt soon
– The attacker was able to access a legacy log file that contained usernames and SHA-1 hashes of passwords, that was generated by the app logins between March 1 and March 21
– We have then deleted the log file, stopped the legacy logging procedure, invalidated the passwords for the accounts present into the log and notified the users involved
– A total of 96564 accounts had their password reset and have been notified with the email communication above. These accounts have not been accessed in any way.
– A total of 3 accounts were accessed by the attackers, before we blocked their activity and reset the passwords. Those 3 users were notified before the others with a different email communication.
– As of March 26, none of the data obtained by the attacker was released publicly, that we know of.
We are working closely with law enforcement on this matter, so unfortunately we can’t share any more details at the moment. We will update this post when we have any news.
If you received the email communication and use the same username/password combination for other services, we strongly recommend that you change the password for those services too.
We are deeply sorry for what happened. We have already contacted a security firm and in the next weeks we will do a thorough code audit and security assessment of our infrastructure and procedures.
We are a small team (3 people) and are trying our best to provide a secure service that you can trust to protect your devices and help you recover them if they are lost or stolen.
