Kategorie: Trojan-Dropper
Trojan-Dropper-Programme sind so konzipiert, dass bösartige Programme, die in ihren Code integriert sind, heimlich auf den Computer des Opfers installiert werden.Diese Art von bösartigem Programm speichert normalerweise eine Reihe von Dateien auf dem Laufwerk des Opfers (normalerweise im Windows-Verzeichnis, im Windows-Systemverzeichnis, temporären Verzeichnis usw.) und startet sie ohne jegliche Benachrichtigung (oder mit falscher Benachrichtigung über einen Archivfehler, ein veraltete Betriebssystemversion, etc.).
Solche Programme werden von Hackern verwendet, um:
Installiere heimlich Trojanische Programme und / oder Viren
Schutz bekannter Schadprogramme vor dem Aufspüren durch Antivirus-Lösungen; Nicht alle Antivirenprogramme können alle Komponenten in dieser Art von Trojanern durchsuchen.

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.

Virtualization/Sandbox Evasion: User Activity Based Checks
Adversaries may employ various user activity checks to detect and avoid virtualization and analysis environments. This may include changing behaviors based on the results of checks for the presence of artifacts indicative of a virtual machine environment (VME) or sandbox. If the adversary detects a VME, they may alter their malware to disengage from the victim or conceal the core functions of the implant. They may also search for VME artifacts before dropping secondary or additional payloads. Adversaries may use the information learned from Virtualization/Sandbox Evasion during automated discovery to shape follow-on behaviors.(Citation: Deloitte Environment Awareness)
Adversaries may search for user activity on the host based on variables such as the speed/frequency of mouse movements and clicks (Citation: Sans Virtual Jan 2016) , browser history, cache, bookmarks, or number of files in common directories such as home or the desktop. Other methods may rely on specific user interaction with the system before the malicious code is activated, such as waiting for a document to close before activating a macro (Citation: Unit 42 Sofacy Nov 2018) or waiting for a user to double click on an embedded image to activate.(Citation: FireEye FIN7 April 2017)

Discovery
The adversary is trying to figure out your environment.
Discovery consists of techniques an adversary may use to gain knowledge about the system and internal network. These techniques help adversaries observe the environment and orient themselves before deciding how to act. They also allow adversaries to explore what they can control and what’s around their entry point in order to discover how it could benefit their current objective. Native operating system tools are often used toward this post-compromise information-gathering objective.
