By manipulating the Address Resolution Protocol (ARP), attackers can intercept, modify, or block network traffic between devices without the victims being aware of it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Because ARP is a fundamental component of local network communication, successful ARP spoofing attacks can lead to data theft, session hijacking, and other security

addresses to physical device addresses, known as <strong>MAC addresses<\/strong>, within a local network.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When a device wants to communicate with another device on the same network, it first uses ARP to determine which MAC address corresponds to the target IP address.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This process allows network traffic to reach the correct device.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_ARP_Spoofing_Works\"><\/span>How ARP Spoofing Works<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">In an ARP spoofing attack, a malicious actor sends forged ARP messages to devices on the local network.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These fake messages associate the attacker&#8217;s MAC address with the IP address of another trusted device, such as:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>A workstation<\/li>\n\n\n\n<li>A server<\/li>\n\n\n\n<li>The network gateway<\/li>\n\n\n\n<li>A router<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">As a result, network traffic intended for the legitimate device is redirected to the attacker&#8217;s system.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The attacker may then:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Monitor network traffic<\/li>\n\n\n\n<li>Capture usernames and passwords<\/li>\n\n\n\n<li>Modify transmitted data<\/li>\n\n\n\n<li>Inject malicious content<\/li>\n\n\n\n<li>Block communications entirely<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Because the communication often continues to function normally, victims may not notice that their traffic is being intercepted.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\"

between two communicating devices and secretly intercepts all exchanged data.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This allows them to observe or modify information without either party

protecting data from interception on local networks.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">VPNs are particularly valuable when using:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Public Wi-Fi

networks for suspicious ARP activity and unexpected changes in MAC-to-IP address mappings.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Intrusion Detection Systems (IDS) can help identify potential ARP

class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Network devices can be configured to filter suspicious traffic and block forged packets that contain inconsistent or

class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Many enterprise-grade switches support <strong>Dynamic ARP Inspection (DAI)<\/strong>, which validates ARP packets before forwarding them across the network.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This feature helps prevent malicious ARP messages from reaching other devices.<\/p>\n\n\n\n<h3

class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">ARP spoofing is a network-based attack that manipulates ARP communications to redirect traffic through an attacker&#8217;s device. This enables attackers to intercept, monitor, modify, or block communications within a local network. Using encrypted protocols, VPNs, packet filtering, network monitoring, and security features such as Dynamic ARP Inspection can significantly reduce the risk of ARP spoofing attacks.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n<\/div>\n","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"template":"","format":"standard","manualknowledgebasecat":[10],"manual_kb_tag":[6406,6407,990,1763,6400,6401,6402,6403,6404,6405],"class_list":["post-8905","manual_kb","type-manual_kb","status-publish","format-standard","hentry","manualknowledgebasecat-safety","manual_kb_tag-dynamic-arp-inspection","manual_kb_tag-encrypted-connections","manual_kb_tag-network-security","manual_kb_tag-virtual-private-network","manual_kb_tag-arp-spoofing","manual_kb_tag-address-resolution-protocol","manual_kb_tag-mac-address-spoofing","manual_kb_tag-man-in-the-middle-attack","manual_kb_tag-local-area-network","manual_kb_tag-network-monitoring"],"_links":{"self":[{"href":"https:\/\/mybox.com\/help\/en\/wp-json\/wp\/v2\/manual_kb\/8905","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/mybox.com\/help\/en\/wp-json\/wp\/v2\/manual_kb"}],"about":[{"href":"https:\/\/mybox.com\/help\/en\/wp-json\/wp\/v2\/types\/manual_kb"}],"author":[{"embeddable":true,"href":"https:\/\/mybox.com\/help\/en\/wp-json\/wp\/v2\/users\/1"}],"version-history":[{"count":2,"href":"https:\/\/mybox.com\/help\/en\/wp-json\/wp\/v2\/manual_kb\/8905\/revisions"}],"predecessor-version":[{"id":8906,"href":"https:\/\/mybox.com\/help\/en\/wp-json\/wp\/v2\/manual_kb\/8905\/revisions\/8906"}],"wp:attachment":[{"href":"https:\/\/mybox.com\/help\/en\/wp-json\/wp\/v2\/media?parent=8905"}],"wp:term":[{"taxonomy":"manualknowledgebasecat","embeddable":true,"href":"https:\/\/mybox.com\/help\/en\/wp-json\/wp\/v2\/manualknowledgebasecat?post=8905"},{"taxonomy":"manual_kb_tag","embeddable":true,"href":"https:\/\/mybox.com\/help\/en\/wp-json\/wp\/v2\/manual_kb_tag?post=8905"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
