Title: Innovations by Jeonghyun Yi in Malicious Behavior Detection
Introduction
Jeonghyun Yi is an accomplished inventor based in Daejeon, South Korea. He has made significant contributions to the field of cybersecurity, particularly in the detection and deobfuscation of malicious programs. With a total of 2 patents, his work focuses on innovative methods to enhance the security of software applications.
Latest Patents
One of Jeonghyun Yi's latest patents is a "Malicious behavior detection method for detecting malicious behavior by analyzing program code, recording medium and apparatus for performing the same." This method involves generating a first control flow graph (CFG) through dynamic analysis of a program. It also includes generating a second CFG by extracting code blocks likely to be executed by conditional branch instructions. By comparing these CFGs, the method detects hidden code within the program and identifies whether it is malicious. This approach significantly reduces the time required to discover and respond to new types of malicious code.
Another notable patent is the "Deobfuscation method for deobfuscating an obfuscated malicious program, a recording medium and a deobfuscation device that performs the same." This method allows for the deobfuscation of malicious programs that have been obfuscated using various techniques. It involves executing the malicious program to extract memory information containing trampoline code, classifying the type of obfuscation, and then deobfuscating the program accordingly. This innovation enables the effective deobfuscation of techniques related to Original Entry Point (OEP) and Import Address Table (IAT).
