I analysed the following doc https://www.virustotal.com/en/file/2b16 ... /analysis/ It then drops https://www.virustotal.com/en/file/8564 ... /analysis/

I observed some HTTP trafffic to ( but not exluding ) hxxp://huaweideviceng.com/huawei/wp-inc ... /entry.jpg

Files all here - http://www.filedropper.com/potentialzeus

Thanks to MMD for this http://blog.malwaremustdie.org/2015/07/ ... v2000.html which identified the .jpg as the IOC i needed :D
