CCSS (Phishing)

Explanation

The objective of this phishing campaign is to obtain personal information and credit card credentials from unsuspecting individuals.

The fraudulent website used in this campaign closely replicates the appearance of the official CCSS site.
Victims are deceived into believing their social security card is no longer valid and are prompted to provide their personal details to facilitate the delivery of a new card.
Once the individuals have also provided their credit card and LuxTrust details, a confirmation screen is displayed.
Finally, after a brief delay, the user is automatically redirected to the official CCSS website.

All the previously described steps take place on pages under the malicious domain ‘ccss-lu[.]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.
