World football body Fifa has warned that its name is being used in an international phishing scam.
Fifa said that several organisations describing themselves as lottery companies were sending out unsolicited e-mails to internet users, and using Fifa branding to steal personal information, including banking details.
The spoof e-mails tell recipients they have won a lottery prize and request they hand over personal data to claim their prizes.
The lotteries claim to be organised by or in association with Fifa, and the organisers of the Fifa World Cups in Germany and South Africa, in 2006 and 2010 respectively.
Fifa said it was considering taking legal action against the organisations behind the phishing e-mails.
A variant of the Sober worm earlier this year targeted users with the promise of World Cup tickets for next year’s tournament in Germany.
