ICMP Redirect Attack
ICMP Redirect Attack is a type of network attack in which an attacker sends fake ICMP redirect messages to a victim’s computer or router, tricking it into sending traffic to a different destination than intended.
ICMP stands for Internet Control Message Protocol, which is a protocol used to send error messages and operational information about network conditions.
The attack works by taking advantage of the ICMP Redirect feature, which is intended to help network administrators optimize traffic routing. When a computer or router receives an ICMP Redirect message, it updates its routing table to use the new suggested route for future traffic.
However, in an ICMP Redirect Attack, the attacker sends fake ICMP Redirect messages that suggest a malicious route to the target’s device. For example, the attacker could redirect the victim’s computer to send its traffic through the attacker’s server, where it can be intercepted or monitored.
This type of attack is particularly dangerous because it can be difficult to detect and can easily bypass firewalls or other security measures. To prevent ICMP Redirect Attacks, network administrators should implement strong security measures, such as filtering outbound ICMP redirects and disabling ICMP Redirects altogether in some cases.
