All Gmail and Outlook users warned to 'search inbox' for three words immediately

Gmail and Outlook users have been urged to look out for a fake Asda email containing three words as police investigate a surge of reports. Action Fraud says it's been alerted to more than 1,700 of the scam, which offers Asda customers a free prize in exchange for completing a survey.

This freebie is a 36 piece Tupperware set which would normally cost several hundred pounds. "Action Fraud has received 1,754 reports in two weeks relating to fake emails purporting to be from Asda," Action Fraud wrote on X.

"The links in the emails lead to phishing websites that are designed to steal person and financial information." Asda has previously warned about scams using its brand, saying: "There are a number of messages circulating by text messages and emails that are nothing to do with us and may be an attempt to capture your personal details.

"Recent messages include supermarket voucher giveaways, prize draws, reminders to collect a package and money off promotions. Please always read a message carefully before clicking on it and check the link before you enter your details.

"An official Asda competition or giveaway should link to an Asda website such as asda.com or george.com. Spelling mistakes or grammatical errors are also clues that a post could be a fake." Don’t click on unsolicited links in messages, even if they appear to come from a trusted contact.

If you think you've fallen for a scam, report it to Action Fraud on 0300 123 2040 or use its online fraud reporting tool. Replying to Action Fraud, another Twitter user said; "I received a fake text from "Vodafone" stating that I had over 5000 points to use before they expired in 3 days' time. The message shows you a variety of different things to exchange the points for, electric toothbrush, amazon gift card 299, apple pay 299. Smart watch, buds."

"I am sorry to see that you have received this fake message about points to redeem from Vodafone. This is an issue that you can report to ourselves using our online reporting tool found at the Action Fraud website," Action Fraud replied.
