Пока получаются автоматически генерить вот такие саммари.
Движок генерит еще кучу артефактов:
- Исходный отчет в формате HTML
- PDF и HTML отчета, очищенный от рекламы и лишнего мусора
- Скрин сайта
- Текстовую модель отчета (текст, разбитый на главы, абзацы и предложения)
- Модель со связями значимых токенов в тексте (кто кого дропает, откуда качается зараза, кто для кого C2 и т.д.)
- Собственно JSON с индикаторами (движ умеет понять что в отчете идут связки MD5+SHA1+SHA256 (или иные комбинации) и объединить их в хэши одного бинаря)
Движок еще требует иногда заглядывать и проверять что он там нашел, но очень многое он уже делать без моего участия.
Еще потестю и переведу постинг на этот движок.
