dynmx

dynmx プロトタイプ dynmx （ダイナミクスと発音）は、Windows API呼び出しシーケンスに基づいた、行動的なマルウェア特徴のシグネチャベース検出アプローチです。簡略化して言えば、 dynmx は、マルウェアサンドボックスから得られるAPI呼び出しトレース（いわゆるファンクションログ）に対する一種のYARAと考えることができます。したがって、この検出アプローチのデータ基盤は、静的に解析されるマルウェアサンプル自体ではなく、マルウェアサンドボックス内での動的解析中に生成されるデータです。現在、 dynmx は以下のマルウェアサンドボックスのファンクションログをサポートしていま...
