Watch out for this domain name certificate scam
From ICANN, in an article titled "Fraudulent ICANN Domain Name Certificates":
It has been brought to ICANN's attention that some online entities have attempted to sell fraudulent "certificates", which they claim are required to protect generic top-level domain names. The perpetuators of this scam threaten registrants on the protection service with the objective of securing a fee from the registrant. The "certificates" look official and include an unauthorized use of the ICANN logo.
Please note that ICANN does not issue certificates to registrants and does not collect fees from registrants directly.
If you come across anyone trying to sell you a fraudulent certificate like this (or this), please steer clear. And if you ever have a question about the authenticity of anything domain related, we're always here to help.
