Malware spam: "Foreman&Clark Ltd" / "Last Payment Notice" leads to Teslacrypt

This fake financial spam does not come from the long-defunct Foreman & Clark, but instead it comes with a malicious attachment that leads to ransomware.

In the sample I saw, the attachment was named copy_invoice_20419955.zip which contained this malicious obfuscated script which has a VirusTotal detection rate of 2/55. When deobfuscated it becomes a bit clearer as to what it does, with an attempted download from:

46.151.52.196/86.exe?1
softextrain64.com/86.exe?1

This pattern is the same as the spam run yesterday. The downloaded binary has an MD5 of 42b27f4afd1cca0f5dd2130d3829a6bc, a detection rate of 5/55 and the Malwr report indicates that it pulls data from the following domains:

graysonacademy.com
grassitup.com
grupograndes.com
crown.essaudio.pl
garrityasphalt.com
gjesdalbrass.no

The characteristics of this malware indicate the Teslacrypt ransomware.
