Virus e-mail “ATTN: Outstanding Invoices – [37B4C3] [April|May]”

I’ve had two emails today to different addresses with subject lines similar to:

“ATTN: Outstanding Invoices – [4AF8F5] [April|May]”
and
“ATTN: Outstanding Invoices – [37B4C3] [April|May]”

Both contained a .xls attachment.

VirusTotal Report which is currently undetected by all antivirus products.

“41160f6_37B4C3.xls” and “d4cb3b62_4AF8F5.xls”

The 41160f6 and d4cb3b62 (the bit before the _) contains the start of the address it was sent to. For example thecomputerperson_83F32F.xls

As with a lot of these files I’ve had through recently, the attachment appears to be corrupt so no further analysis can be undertaken in Excel.

When opened in notepad the leaks a few things such as the folder it was made in:
file:///C:/EC2C4CD9 aka. C:\EC2C4CD9

Some files seem to reference file:///C:/EC2C4CD1/1.htm and another referenced file:///C:/EC2C4CD9/9.htm. This might suggest there is at least 9 variants of the corrupt excel file they are sending.
