Emotet Emotetは悪名高いマルウェアの一つで、最初は銀行情報を盗むためのトロイの木馬として登場しましたが、次第に他のマルウェアと結合して複数の機能を持つモジュール型マルウェアへと進化しました。主にスピアフィッシング攻撃を通じて初期侵入を試み、単なるランサムウェアにとどまらず、バックドアやダウンローダーなどさまざまな形態へと進化する特徴があります。特に、企業全体のシステムを危険にさらすことができる高度なネットワーク拡散機能を備えています。 ### 2. デモ攻撃シナリオ 1.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.plura.io/ja/video/demo/system/emotet.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
