Security experts have warned of a phishing attack claiming to be a customer survey about McDonald's.
The message links to a phoney survey site which asks a number of questions about the fast food chain, and promises to pay $90 (£58) for filling out the survey.
In order to receive the money, however, victims are asked to hand over financial details such as credit card numbers and security codes to 'process' the payment.
Security firm Sophos said that the unconventional nature and target of the attack could lead some users to fall for the scam.
"It's ironic that some internet users may actually be more likely to hand over their credit card information because they are more used to receiving phishing emails pretending to come from online banks, not burger joints," said Sophos senior technology consultant Graham Cluley.
"The truth is that phishers can use a multitude of disguises, posing not just as online banks, but as social networks, online stores, web email providers and now fast food giants."
