content: I can only guess. Perhaps its an application that has been modified to include Galileo, like a trojan. EDIT: Fairly sure I'm right: https://github.com/hackedteam/melter/blob/master/main.cc This is the main melter for Windows EXE files (otherwise known as PE files). On lines 30-33 you can see the options for running the melter application. It takes an input exe file and an input "RCE Backdoor" (which I assume contains the code for the backdoor program) and outputs a melted exe, a combination of the two that looks to the user as if it is the unmodified original input exe. Verify your files, kids!
