Beware of phishing messages imitating Guichet.lu

There are currently phishing attempts via SMS. Fake SMS messages are being sent to people informing them that they are entitled to a refund and inviting them to visit a fake website that looks like Guichet.lu. On this website, the user is then asked to select their bank and to enter their LuxTrust login details.

If you receive such an SMS, please do not click on the link. If in doubt, please contact the Guichet.lu helpdesk on +352 247 82000.

The right reflexes are:

  • With the exception of users who have activated the eTracking function, Guichet.lu and MyGuichet.lu never contact you via SMS;
  • Always check the web address (URL) in your browser: The URLs used by Guichet.lu and MyGuichet.lu are:
    • Guichet.lu: https://guichet.public.lu/
    • MyGuichet.lu: https://services-publics.lu/
