Classe: Trojan-Downloader
Programas classificados como Trojan-Downloader baixam e instalam novas versões de programas mal-intencionados, incluindo Trojans e AdWare, em computadores vitimados. Uma vez baixados da Internet, os programas são iniciados ou incluídos em uma lista de programas que serão executados automaticamente quando o sistema operacional for inicializado. As informações sobre os nomes e locais dos programas baixados estão no código do Trojan ou são baixadas pelo cavalo de Tróia a partir de um recurso da Internet (geralmente uma página da Web). Esse tipo de programa malicioso é freqüentemente usado na infecção inicial de visitantes de sites que contêm exploits.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-Downloader.Win32.Dofoil

Execution
The adversary is trying to run malicious code. Execution consists of techniques that result in adversary-controlled code running on a local or remote system. Techniques that run malicious code are often paired with techniques from all other tactics to achieve broader goals, like exploring a network or stealing data. For example, an adversary might use a remote access tool to run a PowerShell script that does Remote System Discovery.
T1203
Exploitation for Client Execution
Adversaries may exploit software vulnerabilities in client applications to execute code. Vulnerabilities can exist in software due to unsecure coding practices that can lead to unanticipated behavior. Adversaries can take advantage of certain vulnerabilities through targeted exploitation for the purpose of arbitrary code execution. Oftentimes the most valuable exploits to an offensive toolkit are those that can be used to obtain code execution on a remote system because they can be used to gain access to that system. Users will expect to see files related to the applications they commonly used to do work, so they are a useful target for exploit research and development because of their high utility.
