使用 LiME 和 Volatility 分析記憶體鑑識

使用 LiME(Linux 記憶體提取器)進行 Linux 記憶體擷取,並以 Volatility 3 進行後續鑑識分析。

使用 LiME 和 Volatility 分析記憶體鑑識 是什麼?

此技能專為安全分析師與 SOC 團隊設計,提供完整的 Linux 記憶體鑑識工作流程:使用 LiME 核心模組擷取實體記憶體映像,再透過 Volatility 3 對映像進行深入分析。支援多種分析插件,如 linux.pslist(程序列表)、linux.bash(Bash 歷史命令)、linux.sockstat(網路連線狀態)及 linux.lsmod(核心模組檢查)等。可用於調查安全事件、建立檢測規則或驗證監控覆蓋範圍。腳本範例涵蓋命令列與 Python 程式化兩種使用方式,並清楚說明各分析步驟的目標與前置條件。此技能適用於任何支援 Volatility 3 的環境,並需在受授權的測試或實驗環境中執行。

使用 LiME 和 Volatility 分析記憶體鑑識 是做什麼的?

使用時機

  • 調查需要分析記憶體鑑識的安全事件時
  • 為此領域建立檢測規則或威脅獵捕查詢時
  • SOC 分析師需要此分析類型的結構化程序時
  • 驗證相關攻擊技術的安全監控覆蓋範圍時

前置條件

  • 熟悉安全運作概念與工具
  • 能存取安全執行的測試或實驗環境
  • 已安裝 Python 3.8+ 及所需依賴套件
  • 取得任何測試活動的適當授權

操作說明

使用 LiME 核心模組擷取 Linux 記憶體,再以 Volatility 3 從記憶體映像中萃取鑑識證據。

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

# Volatility 3 分析
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

# 程式化使用 Volatility 3
context = contexts.Context()
automagics = automagic.available(context)

關鍵分析步驟:

  1. 使用 LiME 擷取記憶體(格式為 lime 或 raw)
  2. 使用 linux.pslist 列出程序,並與 linux.psscan 比對
  3. 使用 linux.bash 提取 Bash 命令歷史紀錄
  4. 使用 linux.sockstat 列出網路連線
  5. 使用 linux.lsmod 檢查已載入的核心模組,以偵測 rootkit

範例

# 完整鑑識工作流程
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
