Attached is a malicious Word document adb-102288-invoice.doc which has a VirusTotal detection rate of just 1/53, the Malwr report shows there are macros in the document then try to run when it is open. If macros are enabled, this then downloads and executes a malicious binary from http://pro-pose-photography.co.uk/fair/1.exe which also has a pretty poor detection rate of 2/53.

According to the Malwr report, this binary then reaches out to the following URLs:$n=pS%3FgfE@%3Dx%7Efa/%24ysusij%2B%2C%2C%20kCbh2tc8ex%3Dnsgr_/%26$B6JR%2C+j3K2./%20SB$%2CIYA/9Y8STPqNxu/j2hfMb6S$%24zqFH.O%2BRg%20%20/T%2D

The IPs in question are (Virpus, US) and (Intergenia, Germany).

The Malware then drops another malicious binary 2.tmp (which looks like a DLL). The VirusTotal detection rate for this is only 1/54. The Malwr report is inconclusive.
