The payload will then notify the C2 it has successfully downloaded and executed the secondary PowerShell payload. It does so using either the HTTPS/HTTP or DNS channels, depending on which method is successful. The payload will construct a message that has the following structure that it will then send to the C2: bye<char uuid[35]>d The message above is sent via a simple HTTPS/HTTP POST request to the C2 server. If that fails, the payload will use DNS tunneling by first issuing a DNS query to resolve the following domain to notify the C2 that the payload will send data to it in subsequent DNS queries: ns1.
