LiME 및 Volatility를 활용한 메모리 포렌식 분석

LiME(Linux Memory Extractor)을 사용하여 Linux 메모리를 수집하고 분석합니다.

LiME 및 Volatility를 활용한 메모리 포렌식 분석란 무엇인가요?

이 스킬은 LiME(Linux Memory Extractor) 커널 모듈을 사용하여 Linux 시스템의 메모리 이미지를 수집한 후, Volatility 3를 이용해 포렌식 아티팩트를 추출하고 분석하는 방법을 제공합니다. 보안 사고 대응 시 메모리 포렌식 분석이 필요한 경우, 탐지 규칙을 구축하거나 위협 헌팅 쿼리를 작성할 때, SOC 분석가가 체계적인 절차를 따라야 할 때 유용합니다. 주요 분석 단계로는 프로세스 목록 확인(linux.pslist, linux.psscan), Bash 명령어 히스토리 추출(linux.bash), 네트워크 연결 확인(linux.sockstat), 로드된 커널 모듈 점검(linux.lsmod) 등을 포함하며, Volatility 3를 프로그래매틱 방식으로 사용할 수도 있습니다. Linux 환경에서 메모리 포렌식 워크플로우를 자동화하고 표준화하는 데 초점을 맞추고 있습니다.

LiME 및 Volatility를 활용한 메모리 포렌식 분석은(는) 무엇을 하나요?

사용 시기

  • LiME과 Volatility를 사용한 메모리 포렌식 분석이 필요한 보안 사고를 조사할 때
  • 이 도메인에 대한 탐지 규칙이나 위협 헌팅 쿼리를 구축할 때
  • SOC 분석가가 이 분석 유형에 대한 체계적인 절차를 필요로 할 때
  • 관련 공격 기술에 대한 보안 모니터링 적용 범위를 검증할 때

사전 요구 사항

  • 보안 운영 개념과 도구에 대한 이해
  • 안전한 실행을 위한 테스트 또는 실습 환경 접근
  • 필요한 종속성이 설치된 Python 3.8+
  • 모든 테스트 활동에 대한 적절한 권한

지침

LiME 커널 모듈을 사용하여 Linux 메모리를 수집한 후, Volatility 3로 분석하여 메모리 이미지에서 포렌식 아티팩트를 추출합니다.

# LiME 메모리 수집
insmod lime-$(uname -r).ko "path=/evidence/memory.lime format=lime"

# Volatility 3 분석
vol3 -f /evidence/memory.lime linux.pslist
vol3 -f /evidence/memory.lime linux.bash
vol3 -f /evidence/memory.lime linux.sockstat
import volatility3
from volatility3.framework import contexts, automagic
from volatility3.plugins.linux import pslist, bash, sockstat

# 프로그래매틱 방식의 Volatility 3 사용
context = contexts.Context()
automagics = automagic.available(context)

주요 분석 단계:

  1. LiME으로 메모리 수집 (format=lime 또는 format=raw)
  2. linux.pslist로 프로세스 목록 확인, linux.psscan과 비교
  3. linux.bash로 Bash 명령어 히스토리 추출
  4. linux.sockstat로 네트워크 연결 확인
  5. linux.lsmod로 로드된 커널 모듈 확인 (루트킷 탐지)

예시

# 전체 포렌식 워크플로우
vol3 -f memory.lime linux.pslist | grep -v "\[kthread\]"
vol3 -f memory.lime linux.bash
vol3 -f memory.lime linux.malfind
vol3 -f memory.lime linux.lsmod
