Clase: Trojan-Downloader
Los programas clasificados como Trojan-Downloader descargan e instalan nuevas versiones de programas maliciosos, incluidos troyanos y AdWare, en las computadoras de las víctimas. Una vez descargados de Internet, los programas se inician o se incluyen en una lista de programas que se ejecutarán automáticamente cuando se inicie el sistema operativo. La información sobre los nombres y las ubicaciones de los programas que se descargan se encuentran en el código troyano, o se descargan del troyano desde un recurso de Internet (generalmente una página web). Este tipo de programa malicioso se utiliza con frecuencia en la infección inicial de visitantes de sitios web que contienen exploits.Más información

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.

Masquerading
Adversaries may attempt to manipulate features of their artifacts to make them appear legitimate or benign to users and/or security tools. Masquerading occurs when the name or location of an object, legitimate or malicious, is manipulated or abused for the sake of evading defenses and observation. This may include manipulating file metadata, tricking users into misidentifying the file type, and giving legitimate task or service names.
Renaming abusable system utilities to evade security monitoring is also a form of Masquerading.(Citation: LOLBAS Main Site) Masquerading may also include the use of Proxy or VPNs to disguise IP addresses, which can allow adversaries to blend in with normal network traffic and bypass conditional access policies or anti-abuse protections.
