FIFA is warning that a long-established e-mail fraud scam now claims to be connected to the World Cups being organized in Russia and Qatar.
FIFA says it has been alerted to e-mails inviting people to submit tenders for World Cup contracts or claim competition prizes.
Recipients are asked to provide personal information or advance payments to the fraudsters.
The scam is known as a "419," named for a section of the Nigerian legal code it violates.
FIFA says the e-mails have no authorization from it, the 2018 World Cup being hosted by Russia or the 2022 tournament in Qatar.
