Serialization and Deserialization

Free4 Points

Overview

Serialization converts objects into a stored or transferable format, while deserialization rebuilds those objects for application use.

In reverse engineering, serialized data is important because it can reveal class structure, state, assumptions, and how the application trusts restored values. Java applications often expose useful clues through object fields, class names, and deserialization paths.

In this lab, you practice analyzing a Java application's serialized data flow and understanding how object state affects program behavior.
