Phishing threat

guichet.lu (Smishing)

Explanation

Threat actors are using a Guichet.lu phishing theme to collect personal information and credit card credentials.

The attack begins with a fake SMS asking to pay a fee.

The SMS text reads as follows:

Veuillez régulariser votre contravention avant sa majoration. Veuillez vous rendre sur: csa-services-public.com

from: +32 7700051066215

Please note the first use of - instead of . in the link and the top-level domain of com instead of lu. The legitimate link is https://csa.services-publics.lu/trpat-fo/jsp/display_home.

When clicking on the link, the victim is taken to the landing page, where they have to enter their license plate number and e-mail address.

Once this information is provided, personal information is requested, after which credit card credentials are asked.

Example

landing_page summary pii credit_card_credentials

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.
