Clase: Backdoor
Las puertas traseras están diseñadas para dar a los usuarios maliciosos el control remoto de una computadora infectada. En términos de funcionalidad, las puertas traseras son similares a muchos sistemas de administración diseñados y distribuidos por los desarrolladores de software. Estos tipos de programas maliciosos hacen posible hacer todo lo que el autor desee en la computadora infectada: enviar y recibir archivos, iniciar archivos o eliminarlos, mostrar mensajes, eliminar datos, reiniciar la computadora, etc. Los programas de esta categoría se utilizan a menudo para unir un grupo de computadoras de víctimas y formar una red zombi o botnet. Esto le da a los usuarios maliciosos control centralizado sobre un ejército de computadoras infectadas que luego pueden ser utilizadas con fines delictivos. También hay un grupo de puertas traseras que son capaces de propagarse a través de redes e infectar a otras computadoras como Net-Worms. La diferencia es que tales Backdoors no se propagan automáticamente (como Net-Worms), sino solo con un "comando" especial del usuario malintencionado que los controla.Más información

TA0002
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.

Scheduled Task
Adversaries may abuse the Windows Task Scheduler to perform task scheduling for initial or recurring execution of malicious code. There are multiple ways to access the Task Scheduler in Windows. The schtasks utility can be run directly on the command line, or the Task Scheduler can be opened through the GUI within the Administrator Tools section of the Control Panel. In some cases, adversaries have used a .NET wrapper for the Windows Task Scheduler, and alternatively, adversaries have used the Windows netapi32 library and Windows Management Instrumentation (WMI) to create a scheduled task. Adversaries may also utilize the Powershell Cmdlet `Invoke-CimMethod`, which leverages WMI class `PS_ScheduledTask` to create a scheduled task via an XML path.
TA0003
Persistence
The adversary is trying to maintain their foothold. Persistence consists of techniques that adversaries use to keep access to systems across restarts, changed credentials, and other interruptions that could cut off their access. Techniques used for persistence include any access, action, or configuration changes that let them maintain their foothold on systems, such as replacing or hijacking legitimate code or adding startup code.

Privilege Escalation
The adversary is trying to gain higher-level permissions. Privilege Escalation consists of techniques that adversaries use to gain higher-level permissions on a system or network. Adversaries can often enter and explore a network with unprivileged access but require elevated permissions to follow through on their objectives. Common approaches are to take advantage of system weaknesses, misconfigurations, and vulnerabilities. Examples of elevated access include: SYSTEM/root level, local administrator, user account with admin-like access, user accounts with access to specific system or perform specific function. These techniques often overlap with Persistence techniques, as OS features that let an adversary persist can execute in an elevated context.
