Internet Protocol (IP) spoofing
Internet Protocol (IP) spoofing is a type of malicious attack where the threat actor hides the true source of IP packets to make it difficult to know where they came from. The attacker creates packets, changing the source IP address to impersonate a different computer system, disguise the sender's identity or both.
