Please note, for example, if you receive a surprising message supposed to come from the Directorate General of Public Finances (DGFIP) with a grip such as “Crypto transactions have been detected on your accounts. Declare them to avoid an increase of 40%“, All followed by a link to a fraudulent site imitating the interface of that of taxes.
If you indeed have cryptocurrencies and you feel concerned, several signs must put your ear in your ear. There is indeed in this type of message an alarmist tone and a concept of emergency suspect. A financial authority will never contact you in this way to ask you for personal data and a fortiori banking. Also beware of the sender’s email address or even at the URL to which you find yourself redirected, which, necessarily, differ from the original, often for a single character elsewhere.
As a reminder, you should never click on links from unlined messages (emails or SMS) claiming to come from public finances or from any other institution. If in doubt, go directly to the official website (here that of taxes) and log in to your personal space in order to see if you are really asked for additional information. You can also call your tax center to be clear. Finally, do not hesitate to report any fraudulent message to dedicated platforms as a spam signal.
