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.Adload

Stealth
The adversary is trying to hide and conceal their actions, appearing as normal behavior. Stealth consists of techniques that reduce the likelihood of detection by blending in with legitimate activity or minimizing observable signals. These techniques are characterized by concealment behaviors, such as avoiding, obfuscating, or mimicking normal operations, without modifying security controls or compromising collection and monitoring feeds. The goal is to remain indistinguishable from benign activity while leaving defensive systems intact.

Double File Extension
Adversaries may abuse a double extension in the filename as a means of masquerading the true file type. A file name may include a secondary file type extension that may cause only the first extension to be displayed (ex:
File.txt.exe may render in some views as just File.txt). However, the second extension is the true file type that determines how the file is opened and executed. The real file extension may be hidden by the operating system in the file browser (ex: explorer.exe), as well as in any software configured using or similar to the system’s policies. * © 2026 The MITRE Corporation.
