To obtain a job, the Trojan builds a subdomain that has the following structure and issues a DNS query to the C2 server: c<unique identifier><job identifier padded with ‘0’ to make three digits><sequence number>c The generated subdomain is then subjected to a number-to-character substitution function that is the inverse of the Table 4, which effectively converts all the digits in the subdomain into characters
