tshark
提取TCP流量的data字段：
tshark -r 1.pcapng -Y tcp -T fields -e tcp.segment_data > tcp.txt
过滤器
抓包过滤器
抓取源地址为192.168.1.1，目的端口为80的流量
1 | src host 192.168.1.1 && dst port 80 |
抓取192.168.1.1和192.168.1.2的流量
1 | host 192.168.1.1 || host 192.168.1.2 |
过滤mac地址：
1 | ether host 00:88:ca:86:f8:0d |
过滤IP地址：
1 | host 192.168.1.1 |
过滤端口：
1 | port 80 |
过滤协议：
1 | arp |
结合逻辑符号综合过滤
1 | host 192.168.1.1 && port 8080 |
显示过滤器
过滤IP地址：
1 | ip.addr == 192.168.1.1 过滤该地址的包 |
过滤端口：
1 | tcp.port == 80 过滤tcp中端口号为80的包 |
结合逻辑符综合过滤：
1 | ip.src == 192.168.1.1 and ip.dst == 172.16.1.1 |
常用
Nmap扫描出的靶机开放的端口
TCP协议的三次握手
第一次：发送 SYN 包
第二次：服务器收到SYN包 同时自己也发一个SYN包 即 SYN+ACK 包 此时服务器进入SYN_RECV状态
第三次：客户端收到服务器的包 向服务器发送确认包 ACK 完成三次握手
因此可以得知：SYN标志表示建立连接，ACK表示响应，查看开放端口，肯定会返回ACK标志，找
端口即为找ACK标志
wireshark：
ip.src == 192.168.204.133 && tcp.flags.syn == 1 && tcp.flags.ack == 1
tcpdump：
tcpdump -n -r 1.pcapng 'ip src 192.168.204.133 and tcp[13] =18' | awk '{print $3}' | sort -u
USB流量
工具：knm
键盘流量
USB协议数据部分在Leftover Capture Data域中，数据长度为八个字节。其中键盘击键信息集中在第三个字节中。键位映射关系参考：《USB键盘协议中键码》中的HID Usage ID。
步骤：
tshark命令提取cap data
tshark -r usb.pcap -T fields -e usb.capdata > usbdata.txttshark -r usb.pcap -T fields -e usb.capdata | sed '/^\s*$/d' > usbdata.txt（去空行）将数据还原成键位
提取出来的数据可能会带冒号，也可能不带，但是一般的脚本都会按照有冒号的数据来识别。
有冒号时提取数据的

鼠标流量
USB协议鼠标数据部分在Leftover Capture Data域中，数据长度为四个字节。
第一个字节代表按键，当取0x00时代表没有按键，为0x01时代表按左键，为0x02时代表按右键。
第二个字节可以看成是一个signed byte类型，其最高位为符号位，当这个值为正时，代表鼠标水平右移多少像素，为负时，代表水平左移多少像素。
第三个字节与第二字节类似，代表垂直上下移动的偏移。
步骤：
tshark命令提取cap data
tshark -r usb.pcap -T fields -e usb.capdata > usbdata.txttshark -r usb.pcap -T fields -e usb.capdata | sed '/^\s*$/d' > usbdata.txt（去空行）将鼠标数据还原鼠标移动轨迹
