Nouveau: Securisez vos certificats avec GouvCheck [DD-000347-D3534] _{^(2024-10-14)}

Overview

Threat actors collecting personal information, credit card and LuxTrust credentials

Explanation

This phishing campaign involves collecting personal information, credit card and LuxTrust credentials by impersonating “Centre commun de la sécurité sociale (CCSS)”.

The fake email claims that the application “GouvCheck” is required to validate certificates related to CCSS & CNS. The activation of this application is supposedly done by clicking the “Activer mon GouvCheck” button.

Clicking the button redirects the user to a landing page where they are first asked to provide some personal information. The next page also requests private data, such as the phone number and address. Following that, the user is prompted to enter their credit card details. Finally, LuxTrust credentials are requested.

Afterwards, a confirmation message appears, and once the phishing attack is completed through the “Finir” button, the user is redirected to the legitimate CCSS website. All the previous steps have taken place on pages under the malicious domain ‘gouvcheck-ccss[.]com’ .

Prevention

If you are uncertain about the authenticity of an email, do not hesitate to contact the entity that seems to have sent you the email using a safe communication manner, using the phone for example (no phone number from the untrusted email must be used in order to verify the authenticity).
If you are working for the Luxembourgish government or are using any of the GOVCERT.LU services, it is important to forward phishing emails to us (using Reporting an incident or the Outlook button). This will allow us to take down phishing websites and protect members of our constituency.
