• Executing a process using CreateProcess or through a CMD shell
• Listing and terminating processes
• Downloading and uploading files from and to C&C

Communication with the C&C is realized by sending and receiving packets of a fixed form through a TCP connection. The format of packets can be visualized on the diagram below and represent an array of bytes of dynamic length with a 77 bytes header that stores the RC4 key used for payload encryption (the key is created by concatenating each fourth byte)
