Latest Patents

Sunjun Lee's latest patents include a method for evaluating the risk of data leakage in applications. This method involves extracting a DEX (Dalvik Executable) file and a so (Shared Object) file from a mobile application's APK file. It further includes steps for parsing the DEX file, translating the content of the so file into Intermediate Representation (IR), and generating a call-reference structure to output weakness information based on designated risks. This innovation aims to extend the call-reference coverage of Android applications.

Another significant patent by Lee is a device and method for bypassing analysis evasion techniques. This method includes loading a dummy DEX file and parsing a dummy method from it. It identifies whether a function is a bypass target and changes the branch target point accordingly. This allows for the execution of a modulated framework with a bypass code, enhancing the security measures against analysis evasion.
