"Payroll Received by Intuit" spam / Cryptowall

I haven't seen any fake Intuit spam for a while. This one comes with a malicious attachment:

Date:      Fri, 1 Aug 2014 07:59:12 -0600 [09:59:12 EDT]
From:      Intuit Payroll Services [IntuitPayrollServices@payrollservices.intuit.com]
Subject:      Payroll Received by Intuit

Dear, [redacted]
We received your payroll on August 01, 2014 at 09:01 AM EST.

Attached is a copy of your Remittance. Please click on the attachment in order to view it.

Please note the deadlines and status instructions below: If your payroll is received
BEFORE 5 p.m., your Direct Deposit employees will be paid two (2) banking days from the
date received or on your paycheck date, whichever is later.  If your payroll is received
AFTER 5 p.m., your employees will be paid three (3) banking days from the date received
or on your paycheck date, whichever is later.  YOUR BANK ACCOUNT WILL BE DEBITED THE DAY
BEFORE YOUR CHECKDATE. Funds are typically withdrawn before normal banking hours so
please make sure you have sufficient funds available by 12 a.m. on the date funds are to
be withdrawn. Intuit must receive your payroll by 5 p.m., two banking days before your
paycheck date or your employees will not be paid on time.  Intuit does not process
payrolls on weekends or federal banking holidays. A list of federal banking holidays can
be viewed at the Federal Reserve website. Thank you for your business.

Sincerely, Intuit Payroll Services

The attachment in this case is called Remittance.zip and it contains a malicious executable Remittance.exe which has a VirusTotal detection rate of 9/53.

According to the evidence of this very detailed ThreatTrack report [pdf], this is a version of Cryptowall. It makes network connections to various sites including the now-familiar 94.23.247.202.
