SMS Guichet.lu (Smishing) _{^(2022-12-22)}

Overview

Threat actors collecting online banking credentials

Explanation

Threat actors are using a phishing campaign that mimics the appearance of the official Luxembourgish government website (https://gouvernement.lu/fr.html).

The attack begins with a seemingly legitimate SMS that tells the recipient that they are eligible for a tax refund and provides a link to follow. However, when the link is clicked, the user is redirected to a fake version of the gouvernement.lu website. On this page, the victim is asked to choose their bank from a list of options, including Bilnet, Spuerkees, ING, eboo banque and BGL BNP Paribas.

After selecting their bank, the victim is redirected to a fake login form that is themed to match the bank they selected.

The ultimate goal of this phishing attack is to collect the victim’s banking login 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.
