According to Sophos reearchers, spammers recently began sending out phishing e-mails that pose as a warning from Amazon.com that the user's account is about to expire -- the e-mails then claim that an attached form needs to be filled out to continue using Amazon.

"Sophos products detect the attached file as Troj/Phish-AZ and intercept the message as spam," writes Sophos' Graham Cluley.

"If you made the mistake of opening the attachment, you would be faced with a web form which asks you for your credit card details, date of birth and so forth before uploading them to a remote web server," Cluley writes.

Go to "Amazon phishing attack claims your account is about to expire" to read the details.
