static_file_analysis
1.0.0
Анализ вредоносных файлов в глубине с правилами Clamsscan и Yara.
Этот инструмент, написанный в Python Langage, создает связь между моллюском и Ярой. Это может помочь вам забить файл подозреваемого, может создать график визуального дерева для быстрого отображения файлов (родительский тип, тип, подозреваемый или опасное содержание) и может вычислить индикатор компромиссии. Он использует CLAMAV для извлечения встроенных файлов и создания дерева JSON, затем отправляет все смеси по смещенным файлам в Yara с контекстом (в переменных Externs), чтобы проверить правила. Если правила соответствуют, это дает счет этого правила. Оценка правила MAX добавляется к вершине дерева, вы можете добавить счет Globale, который использует все оценки, найденные для показателя коэффициента. Дополнительная функция, инструмент может извлечь конкретный шаблон (URL, хост, IP, ...).
Мой Docker Contener содержит инструменты статического анализа и другие инструменты для глубокого анализа, когда соответствует правилам Yara:
Специальные инструменты
Декомпилятор
Эмулятор/песочница
Отладчик/DBI
Другие
Вы можете использовать другие инструменты, которые не включают в мой Docker Contener:

Чтобы создать правила Yara с помощью этого инструмента, вы должны использовать мета -поле:
Вы можете использовать внешние переменные построения с контекстом Clamav и отправить их в Yara с помощью сценария Python (analys.py):
Проверьте путь yara_rules для просмотра образцов!
Я добавил этот инструмент в Services. Я создал запрос на притяжение в сервисе CRITS, но он еще не подтвержден, но вы можете использовать мой репозиторий GitHub до сих пор.
