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: MSWord

Defense Evasion
The adversary is trying to avoid being detected. Defense Evasion consists of techniques that adversaries use to avoid detection throughout their compromise. Techniques used for defense evasion include uninstalling/disabling security software or obfuscating/encrypting data and scripts. Adversaries also leverage and abuse trusted processes to hide and masquerade their malware. Other tactics' techniques are cross-listed here when those techniques include the added benefit of subverting defenses.

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.
