前沿

前四章我们已经成功安装了流影的各个功能，那么接下来我们就看看这个开源工具的实力，本实验将进行多个攻击手段（ip扫描，端口扫描，sql注入）攻击靶机，来看看流影的态感效果

攻击过程

首先本实验ens33网卡作为web控制配置，ens34作为靶机的受体，我们把探针部署在ens34网卡上并启动

[root@localhost ~]# lyprobe -T "%IN_SRC_MAC %OUT_DST_MAC %IPV4_SRC_ADDR %IPV4_DST_ADDR %PROTOCOL %L4_SRC_PORT %L4_DST_PORT %TCP_FLAGS %SRC_TOS %IN_PKTS %IN_BYTES %SRV_TYPE %SRV_NAME %SRV_VERS %DEV_TYPE %DEV_NAME %DEV_VEND %DEV_VERS %OS_TYPE %OS_NAME %OS_VERS %MID_TYPE %MID_NAME %MID_VERS %THREAT_TYPE %THREAT_NAME %THREAT_VERS %SRV_TIME %DEV_TIME %OS_TIME %MID_TIME %THREAT_TIME" -n 127.0.0.1:9995 -e 0 -w 32768 -G -i ens34  #这里作为输入命令

同时打开/etc/rc.local文件，确定有以下内容

#!/bin/bash
# THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES
#
# It is highly advisable to create own systemd services or udev rules
# to run scripts during boot instead of using this file.
#
# In contrast to previous versions due to parallel execution during boot
# this script will NOT be run after all other services.
#
# Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure
# that this script will be executed during boot.

touch /var/lock/subsys/local

~                                                    

然后查看进程

[root@localhost ~]# ps aux |grep lyprobe   #查看lyprobe探针是否启动

 然后浏览器输入http://ip地址:18080/ui,

点击配置> 规则，对各种规则进行设置（ip设置为0.0.0.0，流量如果小的话，阈值可以设置低点，要不然效果不明显，）关于规则具体的参数建议都设置小点（如果用的是流量包回放），不会的看官方文档：流影: 系统配置

然后导入流量包，我这里使用的是tcpreplay回放工具，可以先安装

# 安装tcpreplay回放工具
sudo yum install epel-release
sudo yum install tcpreplay


# 然后导入流量包（流量包在我前面的文章中有）
[root@localhost ~]# cd pcap_file
[root@localhost pcap_file]# ls
dnstun_cobalt_strike.pcap  ip_scan.pcap        mining_monerohash.pcap  sql_inject.pcap
icmptun_ptunnel_ssh.pcap   mining_common.pcap  port_scan.pcap
[root@localhost pcap_file]# tcpreplay -i ens34 dnstun_cobalt_strike.pcap
[root@localhost pcap_file]# tcpreplay -i ens34 ip_scan.pcap
[root@localhost pcap_file]# tcpreplay -i ens34 mining_monerohash.pcap
[root@localhost pcap_file]# tcpreplay -i ens34sql_inject.pcap
[root@localhost pcap_file]# tcpreplay -i ens34 icmptun_ptunnel_ssh.pcap
