Kategorie: Backdoor
Backdoors sollen bösartigen Benutzern die Fernsteuerung über einen infizierten Computer ermöglichen. In Bezug auf die Funktionalität ähneln Backdoors vielen Verwaltungssystemen, die von Softwareentwicklern entworfen und vertrieben werden.Diese Arten von bösartigen Programmen ermöglichen es, alles zu tun, was der Autor auf dem infizierten Computer möchte: Dateien senden und empfangen, Dateien starten oder löschen, Nachrichten anzeigen, Daten löschen, den Computer neu starten usw.
Die Programme in dieser Kategorie werden häufig verwendet, um eine Gruppe von Opfercomputern zu vereinigen und ein Botnet- oder Zombie-Netzwerk zu bilden. Dies gibt bösartigen Benutzern die zentrale Kontrolle über eine Armee von infizierten Computern, die dann für kriminelle Zwecke verwendet werden können.
Es gibt auch eine Gruppe von Backdoors, die sich über Netzwerke verbreiten und andere Computer infizieren können, wie Net-Worms es tun. Der Unterschied ist, dass sich solche Backdoors nicht automatisch verbreiten (wie Net-Worms), sondern nur auf einen speziellen "Befehl" von dem bösartigen Benutzer, der sie kontrolliert.

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.
T1059.001
PowerShell
Adversaries may abuse PowerShell commands and scripts for execution. PowerShell is a powerful interactive command-line interface and scripting environment included in the Windows operating system. Adversaries can use PowerShell to perform a number of actions, including discovery of information and execution of code. Examples include the
Start-Process cmdlet which can be used to run an executable and the Invoke-Command cmdlet which runs a command locally or on a remote computer (though administrator permissions are required to use PowerShell to connect to remote systems). 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.
T1547.001
Registry Run Keys / Startup Folder
Adversaries may achieve persistence by adding a program to a startup folder or referencing it with a Registry run key. Adding an entry to the "run keys" in the Registry or startup folder will cause the program referenced to be executed when a user logs in. These programs will be executed under the context of the user and will have the account's associated permissions level.
TA0004
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.

Registry Run Keys / Startup Folder
Adversaries may achieve persistence by adding a program to a startup folder or referencing it with a Registry run key. Adding an entry to the "run keys" in the Registry or startup folder will cause the program referenced to be executed when a user logs in. These programs will be executed under the context of the user and will have the account's associated permissions level.
