1. Capturing Packets with Scapy:
--------------------------------

from scapy.all import sniff

def packet_callback(packet):
    print(packet.summary())

sniff(prn=packet_callback, count=10)


2. Extracting HTTP Requests:
----------------------------

import dpkt
import socket

def analyze_pcap(filename):
    with open(filename, 'rb') as f:
        pcap = dpkt.pcap.Reader(f)
        for timestamp, buf in pcap:
            eth = dpkt.ethernet.Ethernet(buf)
            if isinstance(eth.data, dpkt.ip.IP):
                ip = eth.data
                if isinstance(ip.data, dpkt.tcp.TCP):
                    tcp = ip.data
                    if tcp.dport == 80 and tcp.data:
                        print("HTTP Request:", tcp.data)

analyze_pcap("capture.pcap")

(Capture using tcpdump / Wireshark)


3. Challenge Task:
------------------
* Write a Python script to detect SYN scans by analyzing a pcap file.
* Identify IPs sending multiple SYN packets without completing handshakes.
