.cab file analysis

Hello all, I just received an email with the subject: “Bill number B81DB5488CC438A2” and the attachment is a lovely .cab file According to VirusTotal the detection rate is 13/57: https://www.virustotal.com/en/file/7342f33a266888e44e0b832fd2f9f339ca4525f35334c4e784ee49a809505035/analysis/1422428804/ so I decided to work on a little analysis of the file.
