What is cache poisoning and what is its effect?

DNS cache poisoning is the act of entering false information into a DNS cache, so that DNS queries return an incorrect response and users are directed to the wrong websites. DNS cache poisoning is also known as ‘DNS spoofing. (Note that this does not actually disconnect the real websites from their real IP addresses.)

What is DNS cache poisoning attack?

Domain Name Server (DNS) spoofing (a.k.a. DNS cache poisoning) is an attack in which altered DNS records are used to redirect online traffic to a fraudulent website that resembles its intended destination.

What is ettercap in Kali?

Ettercap is a free and open source network security tool for man-in-the-middle attacks on LAN. It can be used for computer network protocol analysis and security auditing. It runs on various Unix-like operating systems including Linux, Mac OS X, BSD and Solaris, and on Microsoft Windows.

What is ARP spoofing and how it works?

ARP spoofing is a type of attack in which a malicious actor sends falsified ARP (Address Resolution Protocol) messages over a local area network. Once the attacker’s MAC address is connected to an authentic IP address, the attacker will begin receiving any data that is intended for that IP address.

What is a smart ARP attack?

It seems that these devices may be sending wrong packets which are considered as Smart ARP attacks. Smart ARP is a protocol or application defense which is activated when the machine receives a response to an unsolicited packet or ARP protocol (address resolution protocol)

What is ARP cheating?

In network the Address Resolution Protocol (ARP) is the standard protocol for finding a host´s MAC Address when only its IP Address is known. Anyhow, once there is ARP cheat in network, the data between computers and router will be sent to wrong MAC Address and the connection can’t establish normally.

What is ARP used for?

The Address Resolution Protocol (ARP) is a communication protocol used for discovering the link layer address, such as a MAC address, associated with a given internet layer address, typically an IPv4 address. This mapping is a critical function in the Internet protocol suite.

What is the difference between ARP poisoning and MAC spoofing?

Arp spoofing is more complicated and it includes poisoning the arp cache of target computer. But mac spoofing is legal and can be done without any particular software. Arp spoofing is used to perform a MITM attack as you mentioned.

What is detected ARP cache poisoning attack?

An ARP spoofing, also known as ARP poisoning, is a Man in the Middle (MitM) attack that allows attackers to intercept communication between network devices. The two devices update their ARP cache entries and from that point onwards, communicate with the attacker instead of directly with each other.

What does spoofing a MAC address do?

Spoofing in general means the diverse methods available to control and operate the fundamental address system in different computer networks. So the answer to what is MAC address spoofing is very simple as it means a method for changing or masking the factory-assigned MAC address of a network interface on a device.

What problems can occur with ARP?

In some cases, the use of ARP can lead to a potential security risk. ARP spoofing, or ARP poisoning, is a technique used by an attacker to inject the wrong MAC address association into a network by issuing fake ARP requests.

How do you fix ARP issues?

View the ARP cache on the computer that is experiencing the problem. Compare the output with the correct IPv4 address and MAC address combinations. If an entry is incorrect, clear the ARP cache to resolve the problem.

What is the risks of ARP poisoning in a network?

ARP poisoning allows the attacker to intercept or alter messages to the real MAC address. This attack can only be used on networks that utilize ARP.

What is ARP conflict?

ARP conflicts occur when two hosts with different MAC addresses resolve to the same IP address.
