Projects

  • Development of IDA Pro Plugins

    -

    [IDA Pro, IDAPython, Reverse Engineering]
    The purpose of this project is to add the reference gathering ability on IDA Pro, the most popular reverse engineering tool. Leveraging IDAPython APIs, RefHunter gathers function and data reference information in a selected code snippet, and shows them graphically. This project was introduced in IDA Plugin Contest 2021.

  • Development Static Binary Instrumentation Framework

    -

    [x86 Assembly, ELF, Python]
    Developed the static binary instrumentation framework, "Reassemblabla" which enhanced accuracy of reassembled linux coreutils binary from 0% to 100% using lazy symbolization, which I invented and granted the patient(KR 10-2019-0003090)

  • Development of Annotation Algorithm for Big Traffic Data

    -

    [OpenCV, Pandas, Machine Learning]
    The purpose of this project is to improve the speed of the annotation in machine learning. We improved the time and space complexity of big data annotation to O(n) while the existing sliding window method requires O(n2) for detecting all objects in the entire image. The experiment in the huge traffic dataset "SYNTHIA SET" shows 12 times improved speed in annotating data then the previous sliding window approach. This paper was officially published in…

  • Development of Windows Kernel Malware Detection Algorithm

    -

    [Windows system, Malware analysis]
    Developed open source Antivirus detects and removes kernel rootkit malware. Invented novel PIDB(Process ID Bruteforce) mechanism and succeeded to detect rootkit that can't be detected by COTS antivirus software(ex. V3, Alyac, Kaspersky)

Honors & Awards

  • 2022 HYUNDAI ALGORITHM CONTEST Winner

    Hyundai Mobis Algorithm Contest (현대모비스 알고리즘 경진대회: 일반부)

    Top 5% of all participants(1000+) and won an output award.
    전체 참가자 중 5%에 해당하는 성적으로 장려상을 수상하였습니다.

  • Best Paper Award

    Ministry of Public Administration and Security

    Received the Korean Minister's Award(1st Place), which is the Best Paper Award in the "Conference on Information Security and Cryptography-Winter 2018". I presented my paper "On Designing an Efficient Binary Reassembler".

  • Full Scholarship

    National Security Research Institute (NSRI)

    Received a full scholarship by the National Security Research Institute for masters degree.
    Scholarship: Cyber Security Professional education program for NSR (사이버보안 우수인재 고용계약형 시범사업 장학생)

  • Output Award

    Korea Information Processing Society

    Received the Output Award in the KIPS Spring Conference. In this conference, I presented my paper "Study on Detection Method and Development of the Kernel Mode Rootkit".

  • Bug Bounty Reward

    KISA(Korea Internet & Security Agency)

    Reported vulnerability on "Alyac", an Anti-Virus (AV) program widely used in Korea. By exploiting this vulnerability, an attacker could forcibly terminate the antivirus process, leaving the system exposed to additional threats. I was rewarded $300 from KISA(Korea Internet & Security Agency) by detecting and reporting this bug.
