Class: Trojan-Notifier
Malicious programs of this type are designed to send messages to inform the malicious user controlling it when an infected computer is online. The malicious user will receive information about the infected computer, such as its IP address, the number of the open port, email addresses, etc. The information can be sent by a range of methods: email, a specially crafted request sent to the malicious user’s website, or via instant messaging. Notifiers are used in multi-component Trojans in order to notify malicious users of the successful installation of malicious programs on victim computers.Read more

Command and Control
The adversary is trying to communicate with compromised systems to control them. Command and Control consists of techniques that adversaries may use to communicate with systems under their control within a victim network. Adversaries commonly attempt to mimic normal, expected traffic to avoid detection. There are many ways an adversary can establish command and control with various levels of stealth depending on the victim's network structure and defenses.

Non-Application Layer Protocol
Adversaries may use an OSI non-application layer protocol for communication between host and C2 server or among infected hosts within a network. The list of possible protocols is extensive. Specific examples include use of network layer protocols, such as the Internet Control Message Protocol (ICMP), transport layer protocols, such as the User Datagram Protocol (UDP), session layer protocols, such as Socket Secure (SOCKS), as well as redirected/tunneled protocols, such as Serial over LAN (SOL).
