setup

RUN sed -i -re 's/([a-z]{2}.)?archive.ubuntu.com|security.ubuntu.com/mirror.kakao.com/g' /etc/apt/sources.list

dockerfile이 주어지면 제일먼저 위 구문을 상단에 박아둔다. 한국에 있기 때문에 apt 서버를 카카오미러로 바꾸면 매우 빠르게 도커 파일을 빌드할 수 있음.

run 할 때 -v 옵션과(호스트 머신과 FS공유하기 위함) --cap-add=SYS_PTRACE를 통해 debuggable하게 설정해주면 된다.

베트남 화이트햇 하러 왔다가 메시지를 받고 짬짬이 푼 문제들 !

사실 대회보다 재밌었다 ㅜㅜ. 시간이 별로 없어 올클 하지 못한게 아쉽다 흑흑

obfuscator말고는 모든 문제를 열어보았다. 각 문제별 설명과 풀이는 아래에 있다.

한국가서 나머지 문제 풀어봐야겠다.
