分析 Linux 内核 Rootkit
概述
Linux 内核 rootkit 在 ring 0 层级运行,通过修改内核数据结构来对用户态工具隐藏进程、文件、网络连接和内核模块。检测方法需要使用内存取证(使用 Volatility3 分析物理内存转储)或交叉视图分析(比对 /proc、/sys 和内核数据结构的不一致性)。本 skill 涵盖使用 Volatility3 Linux 插件检测 syscall 表 hook、隐藏内核模块和被修改的函数指针,以及使用 rkhunter 和 chkrootkit 进行实时系统扫描。
前置条件
- 已安装 Volatility3(pip install volatility3)
- Linux 内存转储(通过 LiME、AVML 或 /proc/kcore 获取)
- 与目标内核版本匹配的 Volatility3 Linux 符号表(ISF)
- 用于实时系统扫描的 rkhunter 和 chkrootkit
- 用于比对的已知良好内核镜像
步骤
步骤 1:获取内存转储
使用 LiME 内核模块或针对云实例的 AVML 捕获 Linux 物理内存。
步骤 2:使用 Volatility3 分析
运行 linux.checksyscall、linux.lsmod、linux.hiddenmodules 和 linux.check_idt 插件以检测 rootkit 痕迹。
步骤 3:交叉视图分析
比较来自 /proc/modules、lsmod 和 /sys/module 的模块列表,识别在某一视图中隐藏但在另一视图中存在的模块。
步骤 4:实时系统扫描
运行 rkhunter 和 chkrootkit,检测已知 rootkit 特征、可疑文件和被修改的系统二进制文件。
预期输出
JSON 报告,包含检测到的 syscall hook、隐藏内核模块、被修改的 IDT 条目、可疑的 /proc 差异以及 rkhunter 发现。
