クラス: Trojan-Dropper
Trojan-Dropperプログラムは、コードに組み込まれた悪質なプログラムを犠牲PCに秘密裏にインストールするように設計されています。この種の悪意のあるプログラムは通常、被害者のドライブ（通常はWindowsディレクトリ、Windowsシステムディレクトリ、一時ディレクトリなど）に一定の範囲のファイルを保存し、通知なしで起動します（またはアーカイブエラーの偽の通知、古いオペレーティングシステムのバージョンなど）。このようなプログラムは、以下の目的でハッカーによって使用されています。トロイの木馬プログラムおよび/またはウイルスを秘密裏にインストールして、既知の悪意のあるプログラムがウイルス対策ソリューションによって検出されないようにします。すべてのウイルス対策プログラムがこのタイプのトロイの木馬の中のすべてのコンポーネントをスキャンできるわけではありません。プラットフォーム: Win32
Win32は、32ビットアプリケーションの実行をサポートするWindows NTベースのオペレーティングシステム（Windows XP、Windows 7など）上のAPIです。世界で最も広く普及しているプログラミングプラットフォームの1つです。ファミリー: Trojan-Dropper.Win32.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.
T1497.001
System Checks
Adversaries may employ various system 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.
TA0007
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.
T1018
Remote System Discovery
Adversaries may attempt to get a listing of other systems by IP address, hostname, or other logical identifier on a network that may be used for Lateral Movement from the current system. Functionality could exist within remote access tools to enable this, but utilities available on the operating system could also be used such as Ping,
net view using Net, or, on ESXi servers, `esxcli network diag ping`. T1049
System Network Connections Discovery
Adversaries may attempt to get a listing of network connections to or from the compromised system they are currently accessing or from remote systems by querying for information over the network.
