There are numerous Covid scams and some of the scammers have moved off offering magic remedies and fake Covid tests to Covid passports and Travel certificates instead.
The email title is “IMPORTANT OFFICIAL Invitation for your Covid passport – Digital Covid-19 certificate (receipt #190934152220918221)”
Scammers seem to think that ridiculously long random numbers are somehow impressive.
The message contains paragraphs taken from the government website about vaccination certificates, to try to make it look genuine.
The message then claims that use of such a certificate means no need for PCR testing, quarantine or any other travel restriction or leaving or entering the country.
That bit is false of course even for genuine vaccination certificate holders.
The final part of the email is a link to click to accept the invitation and a link to click to reject it.
Both in fact lead to the same fake website designed to collect your personal information and send it to the scammer.
Make sure to use the correct government websites and to ignore such scam messages.
If you have any experiences with these scams do let me know, by email.
