Tax Spam Malware Warning

The spam filters are currently working overtime catching dubious email messages about tax payments having failed. As you might expect, this is a Tax Spam Malware Warning, so take care before opening anything that tells you that Your Tax Payment failed.

This email, which purports to be from US tax payment service Electronic Federal Tax Payment System (EFTPS), claims that the recipient’s tax payment has been rejected due to a submission error. The message, which includes a sender address and link that are seemingly valid EFTPS addresses, asks the recipient to click a link in order to review details about the error.

Obviously the email is not from the EFTPS, and the link in the message has been disguised so that it appears to point to the genuine EFTPS website. In fact, it is a phishing scam designed to steal personal information from recipients. A sample of the email appear below:

Your Tax Payment ID [random number] is failed

Your Federal Tax Payment ID: 32127292 has been rejected.
Return Reason Code R21 - The identification number used in the Company Identification Field is not valid.

Please, check the information to get details about your company payment in transaction contacts section:
