INTERCEPTING & MODIFYING PACKETS Scapy can be used to: Create packets. Analyze packets. Send/receive packets. But it can't be used to intercept packets/flows. CLASSIC MITM SCENARIO MITM - SNIFFING DATA MITM - MODIFYING DATA 1. Execute the command -…
PACKET_SNIFFER Capture data flowing through an interface. Filter this data. Display Interesting information such as: Login info(username&password). Visited websites. Images. ...etc PACKET_SNIFFER CAPTURE & FILTER DATA scapy has a sniffer function.…
MODIFYING DATA IN HTTP LAYER Edit requests/responses. Replace download requests. Inject code(html/Javascript) Modifying HTTP Requests on the Fly: #!/usr/bin/env python from netfilterqueue import NetfilterQueue from scapy.layers.inet import IP, TCP fr…
Recalculating Content-Length: #!/usr/bin/env python import re from netfilterqueue import NetfilterQueue from scapy.layers.inet import TCP, IP from scapy.packet import Raw def set_load(packet, load): packet[Raw].load = load del packet[IP].len del pack…
Typical Network ARP Spoofing Why ARP Spoofing is possible: 1. Clients accept responses even if they did not send a request. 2. Clients trust response without any form of verification. 1. Run the following command on the victim - Windows 10 Machine. a…
HTTPS: Problem: Data in HTTP is sent as plain text. A MITM can read and edit requests and responses. -> not secure Solution: Use HTTPS. HTTPS is an adaptation of HTTP. Encrypt HTTP using TLS(Transport Layer Security) or SSL(Secure Sockets Layer). ARP…
Capturing passwords from any computer connected to the same network. ARP_SPOOF + PACKET_SNIFFER Target a computer on the same network. arp_spoof to redirect the flow of packets(become MITM) Packet_sniffer to see URLs, usernames, and passwords sent…
Cross-platform hacking All programs we wrote are pure python programs They do not rely on OS-specific resources. Result: They work on any OS with a python interpreter. If packaged, they will work on any OS if even if python is NOT installed.…
DICTIONARIES Similar to lists but use key instead of an index. LISTS List of values/elements, all can be stored in one variable. Improving the Program Using a List of Dictionaries: #!/usr/bin/env python import scapy.all as scapy def scan(ip): arp_req…
