What is DNS and ARP poisoning?

What is DNS and ARP poisoning?

ARP spoofing – Attacker links their MAC address to an authorized IP address already on the network. DNS spoofing – Attacker initiates a threat such as cache poisoning to reroute traffic intended for a specific domain name traffic to a different IP address.

What is the difference between ARP poisoning and DNS poisoning?

In ARP poisoning, the MAC (Media Access Control) address table of the victim host is ‘poisoned’ with false data. As a reactive measure, you can monitor the network traffic of hosts using tools such as Snort or xARP. With DNS poisoning, the DNS server is given information that it thinks is legitimate when it isn’t.

What is DNS poisoning attack?

DNS poisoning, also known as DNS cache poisoning or DNS spoofing, is a highly deceptive cyber attack in which hackers redirect web traffic toward fake web servers and phishing websites.

Are there any other attacks like ARP poisoning?

This is the place where ethical hackers are appointed to secure the networks. Like ARP poisoning, there are other attacks such as MAC flooding, MAC spoofing, DNS poisoning, ICMP poisoning, etc. that can cause significant loss to a network.

How does an ARP spoofing attack affect a network?

In an ARP spoofing attack, a malicious party sends spoofed ARP messages across a local area network in order to link the attacker’s MAC address with the IP address of a legitimate member of the network. This type of spoofing attack results in data that is intended for the host’s IP address getting sent to the attacker instead.

How to detect an ARP cache poisoning attack?

How to Detect an ARP Cache Poisoning Attack. Here is a simple way to detect that a specific device’s ARP cache has been poisoned, using the command line. Start an operating system shell as an administrator. Use the following command to display the ARP table, on both Windows and Linux: arp -a. The output will look something like this:

How to use ettercap to start ARP poisoning?

Step 11 − Click “start” and select “start sniffing”. This will start ARP poisoning in the network which means we have enabled our network card in “promiscuous mode” and now the local traffic can be sniffed. Note − We have allowed only HTTP sniffing with Ettercap, so don’t expect HTTPS packets to be sniffed with this process.
