クラス: Backdoor
バックドアは、悪意のあるユーザーが感染したコンピュータをリモートコントロールできるように設計されています。機能性の面では、バックドアはソフトウェア開発者が設計し配布する多くの管理システムに似ています。これらの種類の悪質なプログラムは、ファイルの送受信、ファイルの起動や削除、メッセージの表示、データの削除、コンピュータの再起動など、感染したコンピュータ上で必要な作業を可能にします。このカテゴリのプログラムは、被害者のコンピュータのグループを結びつけ、ボットネットまたはゾンビネットワークを形成するためです。これにより、悪意のあるユーザーは感染したコンピュータの軍隊を集中管理し、犯罪目的で使用することができます。 Net-Wormのように、ネットワークを介して拡散して他のコンピュータに感染することができるバックドアのグループもあります。違いは、このようなBackdoorは（Net-Wormのように）自動的に広がるのではなく、それらを制御する悪意のあるユーザーからの特別な「コマンド」に限られるということです。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: Backdoor.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.
T1497.002
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.
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.

TA0011
Command and Control
The adversary is trying to communicate with compromised systems to control them. Command and Control consists of techniques that adversaries may use to communicate with systems under their control within a victim network. Adversaries commonly attempt to mimic normal, expected traffic to avoid detection. There are many ways an adversary can establish command and control with various levels of stealth depending on the victim's network structure and defenses.
T1071.001
Web Protocols
Adversaries may communicate using application layer protocols associated with web traffic to avoid detection/network filtering by blending in with existing traffic. Commands to the remote system, and often the results of those commands, will be embedded within the protocol traffic between the client and server.
