BEWARE of telephone, SMS and e-mail scams

The CNS is warning against scams currently being perpetrated by fake calls, text messages and emails trying to pass themselves off as the CNS.

Phishing campaign misusing the CNS and LuxTrust name and logo

In this new fraudulent campaign, they send emails using the identity of the CNS to inform insured persons that they cannot reimburse invoices because important information is missing. You will then be redirected to another fraudulent site, using the stolen identity of LuxTrust, where you will be asked to log in.

We would like to warn you that these messages do not come from the CNS or LuxTrust, do not click on the links and do not log in with your data!

These links lead to websites that are NOT CNS or LuxTrust websites, do not click on them and do not pass on any information!

Fake/scam scalls

The general aim of scam calls is to make the victim call back on a special premium rate number. The scammers normally use numbers registered abroad and when the victim takes the call, it cuts off immediately to prompt the desired call back.

So if you receive a call from a telephone number registered abroad that you do not recognise, remember the following advice:

  • Ignore the call without hanging up: that way, you do not indicate to the scammers that your number is still in service.
  • Never call back a foreign number you do not recognise.
  • Block the caller on your telephone.
  • If the scam calls continue, inform your service provider.
  • Check your telephone bill and file a complaint with the Police in the event of any loss.

There are, however, other forms of scam call, the purpose of which is to check whether your home is occupied. In this case, the caller pretends to work for a company, a government department or an institution, and asks if you are at home. As burglars may use this method, you should never answer questions about the composition of the household, or the times of day the occupants are at home.

Fraudulent phishing campaigns via SMS and email

Large-scale phishing campaigns, both via SMS and email, have been launched using the CNS and CCSS names and logos.

The fraudulent email and SMS messages use the identity and graphic charter of the CCSS/CNS to inform insureds that their social security card has expired.

We would like to point out that these communications do not originate from the CCSS or the CNS, and we warn you not to click on the link provided.

The links take you to web pages that are NOT the CNS or CCSS sites. Do not click on them or provide any information!

The following table will help you distinguish between the genuine website addresses used by the CCSS and the CNS and the falsified addresses used for phishing purposes:
