Final answer:
To begin victim cache poisoning or sending Gratuitous ARP responses to a victim, you would need knowledge of network security and computer networking. These concepts fall under the subject of Computers and Technology.
Step-by-step explanation:
In order to begin victim cache poisoning or sending Gratuitous ARP responses to a victim, you would need to have knowledge and understanding of network security and computer networking. These concepts fall under the subject of Computers and Technology.
Victim cache poisoning involves an attacker sending false or malicious information to a victim device's cache memory. This can be done through techniques such as Address Resolution Protocol (ARP) spoofing or DNS cache poisoning. Gratuitous ARP responses, on the other hand, involve an attacker sending ARP response packets to a network with false information, attempting to manipulate the network's ARP cache.
It's important to note that engaging in any form of unauthorized or malicious activity, including victim cache poisoning, is illegal and unethical. It's always best to use your knowledge and skills in a responsible and legal manner.
