Hi Morning,

The attached file is SCANNED DOCS,jpg.z which is a type of compressed file. If you have the right file decompression software, it will extact a malicious executable SCANNED DOCS,jpg.exe which has a VirusTotal detection rate of 17/55.

According to various automated analysis tools [1] [2] [3] it drops a file %TEMP%\XP000.TMP\M.exe which itself has a detection rate of 19/54. Out of all the standard analysis tools I have used, only Comodo CAMAS identified the network traffic, a POST to:

eyeseen.net/swift/gate.php

This is hosted on a SoftLayer IP of 198.105.221.5 in Singapore. A quick look at VirusTotal indicates a lot of badness on this IP address, so it is probably one worth blocking.

The payload is Pony / Fareit, which is basically a password stealer.
