The configuration data used by the backdoor has the following structure: #pragma pack(push, 1) struct st_cncconfig {   _WORD id;   _BYTE byte2;   _BYTE byte3;   _QWORD pCnCBeg;   _QWORD pCnCEnd;   _QWORD pLastElement; }; #pragma pack(pop) To be able to enter the data into the database, Linux.BackDoor.Fysbis.1 converts the configuration data into the following structure: #pragma pack(push, 1) struct st_crypted_config_data {   _WORD id;   _BYTE byte2;   _BYTE byte3;   char* pCnC;  }; #pragma pack(pop) Before the configuration data is encrypted with the RC4 algorithm, 11 signature bytes are added to the end of the data (11 bytes are stored in the backdoor's body)
