What is DNS Spoofing?
DNS spoofing is a part of computer hacking in which searched domain names are diverted to some other incorrect IP address due to which the traffic of the victim’s system is diverted to attacker’s system. Using DNS spoofing poison is injected into the address resolution protocol of the victim.
Consider that an attacker started DNS spoofing on the system of a victim and diverted the IP of facebook.com to the attacker’s own IP address. If the victim tries to open facebook.com, the DNS will open the attacker’s IP instead of facebook.com. If the attacker does that, there is a big probability of stealing data or cookies from the victim’s system.
