Дизассемблер

Дизассе́мблер — транслятор, преобразующий машинный код в программу на языке ассемблера.

По режиму работы с пользователем делятся на

• Автоматические
• Интерактивные

Примером автоматических дизассемблеров может служить Sourcer. Такие дизассемблеры генерируют готовый листинг, который можно затем править в тектовом редакторе. Пример интерактивного — IDA. Он позволяет изменять правила дизассемблирования, весьма удобный инструмент для исследования программ.

Чаще всего дизассемблер используют для анализа программы (или ее части), исходный текст которой неизвестен — с целью модификации, копирования или взлома. Реже — для поиска ошибок (багов) в программах и компиляторах.

Обычно используется параллельно с отладчиком.
