Linux:使用RKHunter检测Rootkit后门

来自WHY42

下载Rootkit Hunter,进行安装 

tar zxf rkhunter-<version>.tar.gz
cd rkhunter-<version>
./installer.sh --install
./installer.sh --examples
./installer.sh --help

执行系统检测，只需要： 

/usr/local/bin/rkhunter --checkall

RkHunter检测的过程主要如下：

  1. 进行系统命令的检查，主要是系统的二进制文件包括MD5检测
  2. 检测常见的RootKit程序
  3. 第三部分在检测木马以及可疑的文档
  4. 对网络、系统端口、启动文件、用户组配置、SSH配置、文件系统等进行检测
  5. 对应用程序版本进行检测
  6. 进行一个检测总结
