A successful ARP spoofing (poisoning) attack allows an attacker to alter routing on a network, effectively allowing for a man-in-the-middle attack.. In computer networking, ARP spoofing (also ARP cache poisoning or ARP poison routing) is a technique by which an attacker sends Address Resolution Protocol (ARP) messages onto a local area network.
By contrast, in ARP spoofing the answering system, or spoofer, replies to a request for another system's address with the aim of intercepting data bound for that system. A malicious user may use ARP spoofing to perform a man-in-the-middle or denial-of-service attack on other users on the network. Various software exists to both detect and ...
The arptables computer software utility is a network administrator's tool for maintaining the Address Resolution Protocol (ARP) packet filter rules in the Linux kernel firewall modules. The tools may be used to create, update, and view the tables that contain the filtering rules, similarly to the iptables program from which it was developed.
Another example of geolocation spoofing occurred when an online poker player in California used geolocation spoofing techniques to play online poker in New Jersey, in contravention of both California and New Jersey state law. [9] Forensic geolocation evidence proved the geolocation spoofing and the player forfeited more than $90,000 in winnings.
Security features to prevent ARP spoofing or IP address spoofing in some cases may also perform additional MAC address filtering on unicast packets, however this is an implementation-dependent side-effect. Additional security measures are sometimes applied along with the above to prevent normal unicast flooding for unknown MAC addresses. [5]
ARP Spoofing: Sends fake ARP messages to associate the attacker’s MAC address with a target IP, intercepting local network traffic. DNS Spoofing/Poisoning: Redirects DNS queries to malicious servers, leading victims to fake websites. Session Hijacking: Steals session cookies or tokens to impersonate a legitimate user in an active session.
What is spoofing? Spoofing happens when a hacker sends an email that looks like it came from your email address. While AOL tries hard to make sure we take steps to guard against this, if you do suspect you've been spoofed there are steps you can take to secure your account.
An ARP cache [1] is a collection of Address Resolution Protocol entries (mostly dynamic), that are created when an IP address is resolved to a MAC address (so the computer can effectively communicate with the IP address). [2] An ARP cache has the disadvantage of potentially being used by hackers and cyberattackers (an ARP cache poisoning attack).
