Class: Hoax

A hoax is a fake warning about a virus or other piece of malicious code. Typically a hoax takes the form of an e-mail message warning the reader of a dangerous new virus and suggesting that the reader pass the message on. Hoaxes cause no damage in themselves, but their distribution by well-meaning users often causes fear and uncertainty. Most anti-virus vendors include hoax information on their web sites and it is always advisable to check before forwarding warning messages.

Tactics and Techniques: Mitre*

TA0011
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.
T1071.001
Application Layer Protocol: Web Protocols
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.
