[52], RCSession has the ability to use TCP and UDP in C2 communications. Parallel file access is not supported by a lot of clients to date. ICMP communication between hosts is one example. The DNS service can be mapped to a phone book service where we receive the phone number using the name of the person we are looking to communicate with. PLATINUM continues to evolve, find ways to maintain invisibility. a. [37], RARSTONE uses SSL to encrypt its communication with its C2 server. For this, an application creates a software emulation of a terminal at the remote host. Fidelis Cybersecurity.

TELNET provides communication facilities between two hosts using the CLI. The below image helps us to understand the working of this protocol : It can be used for testing and diagnosing remote web/mail servers. MQTT is a publish/subscribe protocol, which is effective for lightweight machine-to-machine (M2M) connectivity over TCP and minimizes data loss.
