Quora fue hackeada y se expusieron datos de usuarios

by Ignacio Van Droogenbroeck4 diciembre, 2018

Uno más y van, Quora, el servicio de preguntas y respuesta, algo más pro que Yahoo Answers, revelo hoy, mediante un correo electrónico enviado a sus usuarios que el viernes, “terceras partes” maliciosas accedieron a sus sistemas y se hicieron con información de los usuarios. 

Según el email aún no tienen precisiones acerca del leak pero que están investigando y que contrataron a una empresa externa que los ayude con la investigación. 

¿Qué se filtro?

  • Información de las cuentas, tales como nombre, email, IP, User ID, passwords encriptados y configuraciones de la cuenta. 
  • Actiones publicas, tales como preguntas, respuestas, preguntas en el borrador, comentarios, votos, etc. 
  • Información importada desde otros servicios como Linkedin. Contactos, intereses, Tokens de Acceso (que según ellos ya invalidaron)

Si bien los passwords estaban encriptados, no es algo menor, ya que si usamos la misma contraseña para acceder a otros servicios, esto podría no ser tan bueno y eventualmente, quienes tienen estos datos podrían intentar y seguir robando información. Así que la recomendación, si es que tenés alguna cuenta en Quora y usas la misma contraseña para otros servicios, es que la cambies. Más vale prevenir que amamantar decía una ex. 

Acá les dejo el texto del email enviado por Quora esta mañana. 

Dear Nacho Van Droogenbroeck,We are writing to let you know that we recently discovered that some user data was compromised as a result of unauthorized access to our systems by a malicious third party. We are very sorry for any concern or inconvenience this may cause. We are working rapidly to investigate the situation further and take the appropriate steps to prevent such incidents in the future.

What Happened

On Friday we discovered that some user data was compromised by a third party who gained unauthorized access to our systems. We’re still investigating the precise causes and in addition to the work being conducted by our internal security teams, we have retained a leading digital forensics and security firm to assist us. We have also notified law enforcement officials.
While the investigation is still ongoing, we have already taken steps to contain the incident, and our efforts to protect our users and prevent this type of incident from happening in the future are our top priority as a company.

What information was involved

The following information of yours may have been compromised:

Account and user information, e.g. name, email, IP, user ID, encrypted password, user account settings, personalization data

Public actions and content including drafts, e.g. questions, answers, comments, blog posts, upvotes

Data imported from linked networks when authorized by you, e.g. contacts, demographic information, interests, access tokens (now invalidated)

Questions and answers that were written anonymously are not affected by this breach as we do not store the identities of people who post anonymous content.

What we are doing

While our investigation continues, we’re taking additional steps to improve our security:
We’re in the process of notifying users whose data has been compromised.
Out of an abundance of caution, we are logging out all Quora users who may have been affected, and, if they use a password as their authentication method, we are invalidating their passwords.
We believe we’ve identified the root cause and taken steps to address the issue, although our investigation is ongoing and we’ll continue to make security improvements.
We will continue to work both internally and with our outside experts to gain a full understanding of what happened and take any further action as needed.

What you can do

We’ve included more detailed information about more specific questions you may have in our help center, which you can find here.
While the passwords were encrypted (hashed with a salt that varies for each user), it is generally a best practice not to reuse the same password across multiple services, and we recommend that people change their passwords if they are doing so.

Conclusion

It is our responsibility to make sure things like this don’t happen, and we failed to meet that responsibility. We recognize that in order to maintain user trust, we need to work very hard to make sure this does not happen again. There’s little hope of sharing and growing the world’s knowledge if those doing so cannot feel safe and secure, and cannot trust that their information will remain private. We are continuing to work very hard to remedy the situation, and we hope over time to prove that we are worthy of your trust.
