The link in the email downloads goes through a legitimate hacked site and then downloads a RAR file from [donotclick]www.equilibrionutriesportiva.com.br/site/wp-admin/network/icons/equilib/fing3234/Planilha-Documento.docx_.rar which has a VirusTotal detection rate of 17/46 and is identified as a trojan downloader.

According to Anubis, the malware then attempts to download additional components from [donotclick]www.equilibrionutriesportiva.com.br/site/wp-admin/network/icons/equilib/fing3234/ie.exe but this seems to generate a 403 error.
