There's a new variant of MiMail. It comes disguised as an email from Paypal. When you run the attachment you are presented with a form that asks for your creditcard details.
The body contains the following message:
Unfortunatly the 4304 DAT file (needed to detect it) for McAfee isn't available for download yet.Dear PayPal member,
PayPal would like to inform you about some important information regarding your PayPal account. This account, which is associated with this email address will be expiring within five business days. We apologize for any inconvenience that this may cause, but this is occurring because all of our customers are required to update their account settings with their personal information.
We are taking these actions because we are implementing a new security policy on our website to insure everyone's absolute privacy. To avoid any interruption in PayPal services then you will need to run the application that we have sent with this email (see attachment) and follow the instructions. Please do not send your personal information through email, as it will not be as secure.
IMPORTANT! If you do not update your information with our secure application within the next five business days then we will be forced to deactivate your account and you will not be able to use your PayPal account any longer. It is strongly recommended that you take a few minutes out of your busy day and complete this now.
DO NOT REPLY TO THIS MESSAGE VIA EMAIL! This mail is sent by an automated message system and the reply will not be received.
Thank you for using PayPal.
