Routing table injection refers to what type of attack?

• A. An attack where an attacker modifies the routing tables to redirect network traffic.
• B. A method to perform SQL injection.
• C. A technique to hijack wireless sessions.
• D. A method to spoof ARP tables.

Answer: (A)

Routing table injection is about tampering with the router’s view of the network so that decisions about where to forward packets are altered. An attacker who injects routes can cause traffic to be redirected through a device they control, enabling interception, modification, or disruption of communications. This is a network-layer attack that targets the routing infrastructure, not a database or application flaw.

This best fits the idea of changing how traffic is steered through the network by modifying routing information, whether via forged routing updates, compromised routers, or misconfigured protocols. It’s different from SQL injection, which targets databases; from session hijacking, which steals an active session token at the application/transport level; and from ARP spoofing, which operates at the local link layer to map IPs to the wrong MAC addresses.
