Class: RiskTool

Programs in this category have a number of functions (such as concealing files in the system, hiding windows running applications, terminating active processes, etc.) which can be used with malicious intent. They are, in themselves, not malicious. Unlike programs classified as NetTool, RiskTool programs are designed to operate on the local computer. If a user has installed such a program on his/her computer, or if it was installed by a system administrator, then it does not pose any threat.

TA0011
Command and Control

Adversaries may communicate using application layer protocols associated with web traffic to avoid detection/network filtering by blending in with existing traffic. Commands to the remote system, and often the results of those commands, will be embedded within the protocol traffic between the client and server.


Protocols such as HTTP/S(Citation: CrowdStrike Putter Panda) and WebSocket(Citation: Brazking-Websockets) that carry web traffic may be very common in environments. HTTP/S packets have many fields and headers in which data can be concealed. An adversary may abuse these protocols to communicate with systems under their control within a victim network while also mimicking normal, expected traffic.
