Diageo, the owners of Guinness, has confirmed it has no link to messages offering prizes to WhatsApp users.
WhatsApp users in Northern Ireland have received the messages offering a hidden prize, but one that can only be claimed by clicking a link and then supplying personal information.
In a statement, Diageo said: "This is not a Guinness competition and appears to be a scam. We would advise anyone who has received this message to not open the link and delete it immediately."
The supposed competition appears on WhatsApp with the caption "Uncover the hidden prize in Guinness Father's Day giveaway". It is next to a photo of a fridge.
Users are asked to click on a link which then goes to a quiz where they are then offered to answer a quiz and choose from several boxes to find the 'golden ticket'.
They are told they have won and to share the link with 20 friends or five WhatsApp groups in order to claim the prize. The scammers appear to be trawling for personal information but it is not clear what monetary gain they are seeking.
It is similar to a WhatsApp-centred scam last year offering the chance to 'win' cans of Heineken, which was described as a scam by the Dutch beer owner.
