Talos has identified two different infection vectors associated with this particular campaign. In order to compromise their victims, the threat actors sent the trojanized Microsoft Word documents, probably via email. The first vector relies on a trojanized document that fetches a remote template and then uses a known exploit. The second vector is a trojanized Word document that prompts the victim to enable macros and run a Visual Basic script. Once the luncher.doc was downloaded, it used CVE-2017-11882, to execute code on the victim's machine
