Background
Danbot is a backdoor that was initially developed in C#, with more recent builds written in C++. It hands a remote operator capabilities including running cmd commands and uploading, downloading, moving, and copying files. Commands reach the implant over either HTTP or DNS and are wrapped in an XML file written to disk; the backdoor component then reads that XML file and decodes and decrypts the instructions it contains.
