Clase: Trojan-Downloader
Los programas clasificados como Trojan-Downloader descargan e instalan nuevas versiones de programas maliciosos, incluidos troyanos y AdWare, en las computadoras de las víctimas. Una vez descargados de Internet, los programas se inician o se incluyen en una lista de programas que se ejecutarán automáticamente cuando se inicie el sistema operativo. La información sobre los nombres y las ubicaciones de los programas que se descargan se encuentran en el código troyano, o se descargan del troyano desde un recurso de Internet (generalmente una página web). Este tipo de programa malicioso se utiliza con frecuencia en la infección inicial de visitantes de sitios web que contienen exploits.Más información

TA0010
Exfiltration
The adversary is trying to steal data. Exfiltration consists of techniques that adversaries may use to steal data from your network. Once they've collected data, adversaries often package it to avoid detection while removing it. This can include compression and encryption. Techniques for getting data out of a target network typically include transferring it over their command and control channel or an alternate channel and may also include putting size limits on the transmission.
T1567
Exfiltration Over Web Service
Adversaries may use an existing, legitimate external Web service to exfiltrate data rather than their primary command and control channel. Popular Web services acting as an exfiltration mechanism may give a significant amount of cover due to the likelihood that hosts within a network are already communicating with them prior to compromise. Firewall rules may also already exist to permit traffic to these services.
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.
T1102.002
Bidirectional Communication
Adversaries may use an existing, legitimate external Web service as a means for sending commands to and receiving output from a compromised system over the Web service channel. Compromised systems may leverage popular websites and social media to host command and control (C2) instructions. Those infected systems can then send the output from those commands back over that Web service channel. The return traffic may occur in a variety of ways, depending on the Web service being utilized. For example, the return traffic may take the form of the compromised system posting a comment on a forum, issuing a pull request to development project, updating a document hosted on a Web service, or by sending a Tweet.
