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.Família: Trojan-Dropper.Shell.Agent

TA0005
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.
T1070.004
File Deletion
Adversaries may delete files left behind by the actions of their intrusion activity. Malware, tools, or other non-native files dropped or created on a system by an adversary (ex: Ingress Tool Transfer) may leave traces to indicate to what was done within a network and how. Removal of these files can occur during an intrusion, or as part of a post-intrusion process to minimize the adversary's footprint.
T1564.001
Hidden Files and Directories
Adversaries may set files and directories to be hidden to evade detection mechanisms. To prevent normal users from accidentally changing special files on a system, most operating systems have the concept of a ‘hidden’ file. These files don’t show up when a user browses the file system with a GUI or when using normal commands on the command line. Users must explicitly ask to show the hidden files either via a series of Graphical User Interface (GUI) prompts or with command line switches (
dir /a for Windows and ls –a for Linux and macOS). * © 2026 The MITRE Corporation. This work is reproduced and distributed with the permission of The MITRE Corporation.
