Classe: Trojan-Dropper
Os programas do Trojan-Dropper são projetados para instalar secretamente programas maliciosos embutidos em seus códigos nos computadores das vítimas. Esse tipo de programa malicioso geralmente salva vários arquivos na unidade da vítima (geralmente no diretório do Windows, no diretório de sistema do Windows, no diretório temporário, etc.) e os lança sem qualquer notificação (ou com notificação falsa de um erro de arquivamento). versão desatualizada do sistema operacional, etc.). Tais programas são usados por hackers para: instalar secretamente programas de Tróia e / ou vírus que protejam programas maliciosos conhecidos de serem detectados por soluções de antivírus; nem todos os programas antivírus são capazes de escanear todos os componentes dentro desse tipo de trojans.Plataforma: Win32
O Win32 é uma API em sistemas operacionais baseados no Windows NT (Windows XP, Windows 7, etc.) que oferece suporte à execução de aplicativos de 32 bits. Uma das plataformas de programação mais difundidas do mundo.Família: Trojan-Dropper.Win32.Agent

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.

Protocol Tunneling
Adversaries may tunnel network communications to and from a victim system within a separate protocol to avoid detection/network filtering and/or enable access to otherwise unreachable systems. Tunneling involves explicitly encapsulating a protocol within another. This behavior may conceal malicious traffic by blending in with existing traffic and/or provide an outer layer of encryption (similar to a VPN). Tunneling could also enable routing of network packets that would otherwise not reach their intended destination, such as SMB, RDP, or other traffic that would be filtered by network appliances or not routed over the Internet.
There are various means to encapsulate a protocol within another protocol. For example, adversaries may perform SSH tunneling (also known as SSH port forwarding), which involves forwarding arbitrary data over an encrypted SSH tunnel.(Citation: SSH Tunneling)
Protocol Tunneling may also be abused by adversaries during Dynamic Resolution. Known as DNS over HTTPS (DoH), queries to resolve C2 infrastructure may be encapsulated within encrypted HTTPS packets.(Citation: BleepingComp Godlua JUL19)
Adversaries may also leverage Protocol Tunneling in conjunction with Proxy and/or Protocol Impersonation to further conceal C2 communications and infrastructure.
