OS : IBM AIX 5.3 64 bit


프로젝트 홈페이지 : http://www.rootkit.nl/projects/rootkit_hunter.html
소스 다운로드 : http://sourceforge.net/projects/rkhunter/

이글을 쓰는 시점에 rootkit hunter 은 1.3.8 까지 나와있었다.

어느날 AIX 시스템내에 뭔가 불순한(?) 움직이 포착되었다...

뭐... 대부분 AIX 시스템 내부로 구축할 정도면

약간(?)의 규모 이상이라고 생각되며,

차라리 거대한 시스템이라면 방화벽, 네트워크 장비 정책등 훌륭히 갖추어 졌겠지만,

항상 문제는 아주 작지도 아주 크지도 않은 어설픈 시스템에 해당되는 사항이다.

3일동안 열심히 삽질했다...

1.3.8 버젼을 설치하고나선... 안되는것이었다 -_-ㅋ

아래와 같이

> rkhunter -c
Invalid BINDIR configuration option: Invalid directory found: .

업데이트도 해보고 갖은 것을 모두 해봤지만, 실행이 되질 않았따. -_-...

결국은 포기하고 그 이전버젼을 다운로드 받으려고 하는 순간.... 소스포지에서는 1.3.8버젼 밖에 안되는것이었다... 헉 -_-...

그래서 1.3.6을 어렵게 구해서 해보니 잘되었다.... -_-... 내 3일 ㅜㅜ

설치 방법과 절차이다.

1. 시스템 필요 요소
    - 호환되는 시스템이어야 한다.(홈페이지참조) -> 거의 리눅스 계열은 다 된다고 보면 됨..
    - BASH 쉘

2. 사전 준비
    a. BASH 쉘 설치하기
        - www.ibm.com 으로 가서 검색을 열심히 하면 찾을수 있다 -_-... 매번 헷갈린다. 이문서의 제일 위에 있는 bash-3.0-1.aix5.1.ppc.rpm 파일을 다운로드 받아 서버로 전송한다.
        - rpm 으로 되어 있기 때문에
          root로
          rpm -ivh bash-3.0-1.aix5.1.ppc.rpm 명령을 통해 설치하면 끝.... 
          $> bash 입력
          $> echo $SHELL ==> bash가 나오면 정상 설치 완료
     b. lynx or wget 등 설치하기
         - 검색 정보에 대한 데이터베이스를 웹을 통해 가지고 오는데 위의 해당 프로그램들이 설치되어 있지 않으면
           정보를 update하지 못한다.
         - rpm파일로 되어 있기 때문에 위의 a의 내용 참고
     c. rkhunter-1.3.6.tar.gz 파일을 설치하기(root로 실행)
         - 서버로 upload 로드 뒤
         - gzip 명령을 통해 압축을 푼다.
            gzip -d rkhunter-1.3.6.tar.gz
         - tar로 묶여져 있는 파일을 푼다.
            tar xvf rkhunter-1.3.6.tar
         - 설치하기
            위의 tar를 풀면 rkhunter-1.3.6 디렉토리 안에
            installer.sh 파일이 존재하며
           다음과 같이 간단히 설치할수 있다.
           $> installer.sh --install
            /usr/local/bin/rkhunter 파일이 생성된다.(기본 설치시...)
 $> installer.sh --install

몇일전 NAT를 걸어놨던 외부 IP로 부터 리눅스 시스템이 해킹을 당했다 -_-ㅋ

아놔....

무슨 광고 사이트가 뜨고 침입한 녀석 IP까지 찾았다...

외국 IP이라... 하앍....

오라클 리스너 설정 변경, apache 웹 시스템 적용 등

알수 없는 짓들만 실컷(?) 하고 나갔다....

그래서 간만에 rkhunter를 사용하여 점검중에 있다.

뭐 간단히 /tmp/에 파일을 복사하여 넣고

gzip -d rkhunter-1.3.6.tar.gz (압축 풀고)
tar xvf rkhunter-1.3.6.tar (타르 파일 풀고)


/tmp/rkhunter-1.3.6/ 디렉토리 파일이 풀린다...

뭐. 설치는 어렵지않다.

/tmp/rkhunter-1.3.6/installer.sh --install

/tmp/rkhunter-1.3.6/installer.sh 쉘을 치면 설명이 나온다.... 한번 읽어 보면 좋다.

# rhunter -c

자 끝났다... 실제 체크 옵션의 Warning 부분인데.. 어라.. 자세히 안나온다

자세한 내용은 /var/log/rkhunter.log를 살펴보자... 그럼 더 자세한 경고 문구들이 나온다.

조치방법은 워낙 많기 때문에 구글링(www.google.co.kr)을 통해 검색해 보자 ~
