Looking inside ESE 🫣
During incident investigations, we at PT ESC IR regularly encounter the need to analyze databases in the ESE (Extensible Storage Engine) format, since such artifacts can contain a lot of interesting information.
To work with such files more efficiently, it is important to understand how this format is structured internally. Therefore, based on the results of our research, we have prepared a detailed breakdown of the internal structure of ESE (also known as Jet Blue) — Microsoft’s built-in DBMS, which is used in many of the company’s products.
In the article, we explain how data storage is organized at a low level, how pages and records are structured, and also examine implementation details of the engine that may be useful when analyzing database contents and developing your own parsers for working with such files.
🫱 Details — on Habr.
