PRECAUCION EN COINBASE / AUTHY

A todos los que utilizais Coinbase
Si teneis el sistema de verificación AUTHY.

Debeis de eliminar en ajustes la opcion de añadir mas dispositivos

Si teneis el AUTHY en 2 telefonos por ejemplo, anular eso. Si luego vais a a añadirlo en otro dispositivo, pues lo poneis sobre la marcha y luego lo quitais.

En caso de perder el dispositivo utilizar las llaves de seguridad que os dieron al añadir Coinbase a AUTHY

Hay un fallo se seguridad mediante el cual los hackers añaden dispositivos propiedad de ellos a tu cuenta, dejandola a merced de ellos. Por eso debeis anular esta opción y solo activarla si vais a añadir un nuevo dispositivo

Esperamos que este aviso sea de tu interés.

Transcribimos aqui el mensaje original de Coinbase- Authy:


Dear Coinbase user,

We are notifying you because you currently, or have previously, used the Authy app to protect access to a Coinbase account. Due to a recent increase in sophisticated attacks targeting Coinbase users, we are taking extra precaution to protect your account.

In combination with social engineering and password theft, attackers are porting phone numbers (also known as SIM swapping). Once they fraudulently gain control of a user’s phone number, attackers can add new devices to an existing Authy account and take over access to a linked Coinbase account.

To combat these attacks, we will be automatically disabling the Authy multi-device setting and limiting the ability to use SMS to install Authy.

Here are the steps you need to take:
  1. To avoid being locked out of your Coinbase account, please immediately install the Authy app on your current device if you have not already.
  2. If you need to install the Authy app on a new device, you will need to re-enable multi-device in the Authy app settings, though we recommend you disable it again after you have finished adding another device.
  3. Avoid sharing information regarding Coinbase or other bitcoin activity on social media.
  4. If you are still having trouble accessing your Coinbase account, please contact support@coinbase.com.

Thanks,

The Authy Team
