Official statement following the phishing attempt of 09/12/2019 on Coinhouse

Julien Moretto – 13 Sep 2019

Following a fraudulent connection in the tool we use for mailing, Coinhouse was subject to a phishing attempt. This tool being external to our overall system, our platform was not attacked and all funds are in total security.

The attack took place yesterday, consisting in sending out emails to our clients and prospects in an attempt to obtain their login credentials. It started 6:47 PM, Paris time, when an email with the following title “Action required: Verify your Data”, inviting its recipients’ to click on “Verify” was sent. Users that clicked on this link were redirected to a fake website copying the Coinhouse page and its 2 Factor Authentication (2FA) process. Here, they were asked to identify themselves by submitting their mail, passwords, (and 2FA codes for those that had set it up). .

Immediate reaction of our team

Our teams were put on alert immediately and the fake website “app.colnnhouse.” (with an “L” in place of “i) was stated as fraudulent within less than an hour, and considered a dangerous website thanks to our rapid intervention. Coinhouse blocked all access to accounts on the platform for a period of 6 hours, precisely from 7PM to 1AM, Paris time as precautionary procedure. No one could access to the platform nor any of its accounts.

Our platform was not attacked and all funds are in total security. All cryptoasset delivery services are operational. We have however stopped all cryptoasset withdrawals for all assets stored on our platform

1.2. If you hope to do so, you can change your password on the Coinhouse log in section page.

1.3  Remain vigilant with regards to all future emails that you may receive. Whenever you click on a link embedded in an email, systematically verify that you are indeed redirected towards an official website. Put extreme precaution on the URL that you are redirected to, and the email address format of the email you have received. If you have any doubt, the most secure way to access our service is to log on https://www.coinhouse.com and click on “Sign In”
