DNS poisoning is the most common, and most dangerous, type of Internet-based attack. DNS poisoning allows hackers to take control of a system and make it do bad things to its users.
A DNS poisoning attack is usually done through a DNS server that is compromised by a hacker. When that happens, the attacker will attempt to inject a malicious DNS query into the system and use it as a method of accessing the compromised system.
DNS poisoning attacks can be accomplished through a variety of methods. For example, a hacker may purchase a DNS server that is then used to launch a denial of service attack against other systems. Another method that can be used to execute a DNS poisoning attack is through a targeted DDoS attack. In this attack, the hacker will use a botnet to send a large number of UDP packets (and possibly TCP packets) to a variety of target systems.

The most common method of DDoS attack is through a DNS packet attack. The packet that is most commonly used to execute a DNS poisoning attack is the UDP packets that are sent to a target system. If a DDoS attack is successful, the victim will be able to connect to the target system and launch the attack. If a DDoS attack is unsuccessful, the victim will be able to connect to the target system and launch the attack again.
The most common method of ARP poisoning is through the use of an ARP attack. The target system will be able to connect to the victim’s network and send a small packet that contains an ARP request. If the packet is successful, the target system will respond with an ARP response containing the information needed to execute the attack. If the packet is unsuccessful, the target system will not respond at all.
For example, if you wanted to poison the victim network, your poison packet would first attempt to reach the victim’s DNS server, which will then try to resolve the poison packet. The victim’s DNS server will respond with the poison packet, which will then be dropped and never sent again.
ARP poisoning works a little differently because it sends a packet to the target system, but this time for an ARP request instead of a DNS request. The target system is responsible for responding to the ARP request with an ARP response containing the information needed to execute the attack. If the target system does not respond, then the attack will fail.
Both of these poisoning attacks work the same way on the DNS server in question, as the victim sends a DNS request to a valid server that, in turn, will send a DNS query to the target. The response contains the target’s IP address and the poison packets. If the DNS server is already responding to the request, then the DNS server will simply drop these packets and not send any more.
The most common use of this poisoning method is for the victim to request a large amount of data from a specific IP address and then to flood the victim’s DNS server with large amounts of data. The IP address is in the form of a hostname. Many people will simply choose a random one from a list of known IP addresses and use it as the target’s DNS server.
