Wormhole Attack

A network security attack where an attacker captures data packets at one location in a network, tunnels them to another location, and then replays them, disrupting communication or bypassing security measures. This attack is commonly seen in wireless networks, such as ad hoc or sensor networks.

Example: In a corporate Wi-Fi network, an attacker sets up rogue devices to intercept data packets from employees' laptops, tunnels them to a remote server, and replays them to gain unauthorised access to confidential business data.
