The proliferation of large botnets makes spoofing less important in denial of service attacks, but attackers typically have spoofing available as a tool, if they want to use it, so defenses against denial-of-service attacks that rely on the validity of the source IP address in attack packets might have trouble with spoofed packets.
The attacker with the IP 1.1.1.1 sends a packet with a spoofed source IP (3.3.3.3) to the destination 2.2.2.2. (This might already be a security risk, e.g. if 2.2.2.2 always trusts all packets from 3.3.3.3.) 2.2.2.2 now answers the alleged sender 3.3.3.3, which in reality never sent the packet. 3.3.3.3 therefore is receiving an unexpected ...
IP spoofing and ARP spoofing in particular may be used to leverage man-in-the-middle attacks against hosts on a computer network. Spoofing attacks which take advantage of TCP/IP suite protocols may be mitigated with the use of firewalls capable of deep packet inspection or by taking measures to verify the identity of the sender or recipient of ...
In 2021 and 2022 it was part of an investigation by numerous law enforcement agencies into frauds enabled by this caller ID spoofing. It was shut down in November 2022 as the result of Operation Elaborate, a multi-agency investigation led by the Metropolitan Police and supported by Netherlands Police, Europol and Eurojust. As of 2022, it is the ...
In computer networking, ingress filtering is a technique used to ensure that incoming packets are actually from the networks from which they claim to originate. This can be used as a countermeasure against various spoofing attacks where the attacker's packets contain fake IP addresses.
A Smurf attack is a distributed denial-of-service attack in which large numbers of Internet Control Message Protocol (ICMP) packets with the intended victim's spoofed source IP are broadcast to a computer network using an IP broadcast address. [1] Most devices on a network will, by default, respond to this by sending a reply to the source IP ...

The basic protocol used on the Internet is the Internet Protocol (IP), which is usually coupled with additional protocols such as TCP (Transmission Control Protocol [2]) or UDP (User Datagram Protocol). TCP/IP is the protocol set used for email and web browsing. Each protocol has a block of information, called a header, included near the front ...
