The binary attachment is a threat that is often referred to as Fareit. Fareit is known to steal information such as credentials and account information from installed FTP clients and cryptocurrency wallets, and stored passwords in browsers.

For the two samples coming from these spam, we’ve seen them connecting to these to send information:

In addition to stealing data, these samples download other malware including Zeus P2P from:
• ip-97-*.net/zA6.exe
• 119*4/fF3krry.exe
• rot*.com/124Tzh.exe
• ww*
• dev*.com/1mHifVu.exe
• surfa*.com/DJm.exe
• kl*.com/Q4EzT.exe

Other malware seen installed in the system was Cryptolocker.

Samples are detected as Trojan.Pws.Tepfer and Trojan.GenericKD variants.
