LloydsTSB has posted a security notice on its Web site warning customers to beware of a new fraudulent e-mail scam.
The e-mails point customers in the direction of a fake Lloyds TSB site where they are encouraged to enter their Visa debit card details.
The latest scam follows a similar assault on Barclays Bank, which was forced to reduce payment transfer limits after some customers were duped into inputting their personal data at a bogus site.
LloydsTSB says it is aware of only one customer who divulged their details. The copycat site was shut down this morning following an all-night trawl by the bank and the National High Tech Crime Unit.
