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.
A successful ARP spoofing attack allows an attacker to perform a man-in-the-middle attack. Because ARP does not provide methods for authenticating ARP replies on a network, ARP replies can come from systems other than the one with the required Layer 2 address.
Attacks can be from two categories: "Passive" when a network intruder intercepts data traveling through the network, and "Active" in which an intruder initiates commands to disrupt the network's normal operation or to conduct reconnaissance and lateral movements to find and gain access to assets available via the network.
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).
Two common varieties are DNS cache poisoning [2] and ARP cache poisoning. Web cache poisoning involves the poisoning of web caches [3] (which has led to security issues in programming languages, including all Python versions at the time in 2021, and expedited security updates [4]). Attacks on other, more specific, caches also exist. [5] [6] [7]
Ettercap is a free and open source network security tool for man-in-the-middle attacks on a LAN.It can be used for computer network protocol analysis and security auditing.It runs on various Unix-like operating systems including Linux, Mac OS X, BSD and Solaris, and on Microsoft Windows.
Allegations that Silkwood's exposure to plutonium-239 was a deliberate act of radiation poisoning are fueled by the fact that she was in possession of potentially compromising evidence that linked Kerr-McGee with egregious safety violations, encompassing unsafe workplace conditions at the plant, faulty manufacture of fuel rod components that ...
