クラス: Email-Worm
Email-Wormsは電子メールで広がります。ワームは、電子メールメッセージへの添付ファイル、またはネットワークリソース上のファイルへのリンク（例えば、侵害されたWebサイトやハッカー所有のWebサイト上の感染ファイルへのURL）として自身のコピーを送信します。最初のケースでは、感染した添付ファイルが開かれた（起動された）ときにワームコードがアクティブになります。 2番目のケースでは、感染ファイルへのリンクが開かれたときにコードが有効になります。どちらの場合も、結果は同じです：ワームコードが有効になっています。 Email-Wormは、感染した電子メールを送信するためにさまざまな方法を使用します。最も一般的なのは、Windows MAPI機能を使用するMS Outlookサービスを使用してワームのコードに組み込まれた電子メールディレクトリを使用してSMTPサーバーに直接接続することです。 Email-Wormsは、感染した電子メールが送信される電子メールアドレスを見つけるためにいくつかの異なるソースを使用しています：MS Outlookのアドレス帳ハードドライブに格納されたWABアドレスデータベース.txtファイル：ワームはテキストファイルのどの文字列メールボックスは、受信ボックス内の電子メールアドレスを扱います（一部の電子メールワームは、受信ボックスにある電子メールにも「返信」します）。多くのEメールワームは、上記のソースのうちの複数を使用します。 Webベースの電子メールサービスに関連付けられたアドレス帳など、電子メールアドレスの他のソースもあります。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: Email-Worm.Win32.Warezov

Tactics and Techniques: Mitre*
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.
T1204.002
Malicious File
An adversary may rely upon a user opening a malicious file in order to gain execution. Users may be subjected to social engineering to get them to open a file that will lead to code execution. This user action will typically be observed as follow-on behavior from Spearphishing Attachment. Adversaries may use several types of files that require a user to execute them, including .doc, .pdf, .xls, .rtf, .scr, .exe, .lnk, .pif, .cpl, and .reg.
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.
T1497.003
Time Based Evasion
Adversaries may employ various time-based methods to detect and avoid virtualization and analysis environments. This may include enumerating time-based properties, such as uptime or the system clock, as well as the use of timers or other triggers to avoid a virtual machine environment (VME) or sandbox, specifically those that are automated or only operate for a limited amount of time.
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.
