| | Hello World - Spoofing Techniques |
| | Spoofing attack can also be suppressed by configuring routers in such a way that they filter the incoming packets and reject the ones that claim to be from a machine internal to the network. | | | One can prevent ARP spoofing attacks by either stopping the usage of ARP for obtaining the hardware address of a trusted host or by keeping a permanent entry of the hardware address of the trusted host in the ARP caches of the trusting machines. | | | As the majority of our readers are computer science students and taking into consideration the fact that subject like spoofing is not included in the universities educational programs I decided to jump on the question and write an article on it. |

| | Address Resolution Protocol - Wikipedia, the free encyclopedia |
| | The sender broadcasts an ARP packet containing the Internet address of another host and waits for it to respond with its MAC address, which is then stored in a cache for later use. | | | In computer networking using the Internet Protocol suite, the Address Resolution Protocol (ARP) is the method for finding a host's MAC address when only its IP address is known. | | | In addition, InARP is actually implemented as an extension to ARP. |

| | Why spoofing is the number one security problem on the Internet, and how we should fight it |
| | DNS spoofing: This spoofing method will convince the target machine that the machine that it wants to contact (for example www.somecompany.com) is the machine of the attacker, or in an other implementation that the name of the attacker machine is a name with elevated access rights. | | | The use of spoofed ARP responses makes it possible for an attacker to disrupt the network, but more than that makes it possible for the attacker to implement a simple man-in-the middle attack, or in its simplest form to sniff a switched network that would otherwise be non-sniffable. | | | Although full static ARP tables may not be possible as implicit configuration, a partial implementation will also improve the security of shared-segment networks. |

| | Going up the wireless stack |
| | Remember that ARP is a stateless protocol, so the two computers make the assumption that they had previously sent ARP requests and will update their ARP caches with this new, poisoned information. | | | Attackers can use a technique known as ARP spoofing to convince two machines that they are communicating with each other, when both are actually connected to a third computer under hostile control. | | | ARP updates the cache of ARP-to-IP mappings whenever an ARP request (or reply) is received. |

| | TCP/IP Address Resolution Protocol(ARP) |
| | This process is known as ARP Spoofing, and it allows a computer to sniff network traffic even if there is a switch. | | | Since ARP Cache Poisoning results from a lack of security in a protocol that is required for TCP/IP networking to function, you can't fix it. | | | The hacker begins by sending a malicious ARP "reply" (for which there was no previous request) to your router, associating his computer's MAC address with 192.168.0.12 (see Diagram 3). |

| | The ARP program looks in the ARP cache and, if it finds the address, provides it so that the data packet can be sent to the destination. | | | ARP (in Host 1) updates the ARP cache for future reference and then sends the data packet to the destination. | | | A table, usually called the ARP cache, is used to maintain a correlation between each MAC address and its corresponding IP address. |

| | The reason for this is because normal ARPs just tell you their info and sit there, but programs like ettercap want to make sure their fake MAC can't be overwritten by any other valid incoming ARPs, and so consistently rewrite your arp tables every 3 seconds or so. | | | The reason we'd need to block both requests and replies is because the windows ARP table can be overwritten by sender/receiver data in either (even when a persitant entry is made), so to be secure we'd really have to stop both. | | | An attacker has to send arp response very often, because he never knows, if someone or somethings deletes the arp cache in his computer. |

| | Since with ARP spoofing the attacker can make two machines “talk” to each other through his computer, rather than directly, the attacker can control which packets each side can receive, making for a much more reliable hijack. | | | The first step for the attacker (Host Z) is to poison the ARP cache of host X with a spoofed ARP reply, telling Host X that the IP Address of host Y is now associated to the MAC address of the attackers computer (00:00:00:00:00:12). | | | ARP cache poisoning results from a lack of security in the protocol itself. |
