Exploits  CVE-2017-0143, SMB exploit CVE-2017-0146, SMB exploit  These 2 exploits are EternalBlue/Doublepulsar and are used to drop the Stage1 Dropper onto a system.  Installation The Gh0stRAT dropper arrives on a PC through the use of EternalBlue/DoublePulsar.  Once on a victim’s PC, the dropper executable is launched and it decrypts and loads the Gh0stRAT DLL into memory.  It then passes the config buffer to the extracted DLL and calls the exported function (Shellex)  [Screenshot 2] The mainthread of the code.  Note the call at the bottom that calls Shellex Gh0stRAT dll functionality An important note:  In its base state, this sample is damaged, therefore it will not install its services properly.  However, as the service information is included, I will list it anyways.  Additionally, samples downloaded from its distribution server DO install correctly,  and are downloaded during the base dll’s runtime
