Which tool is used to implement ACK tunneling?

• A. AckCmd
• B. HTTP Tunneling
• C. Flooding
• D. ICMP protocol

Answer: (A)

ACK tunneling relies on a covert channel that smuggles data inside TCP acknowledgment packets, using the normal flow of TCP traffic to carry commands and responses without raising obvious alarms. AckCmd is a tool built specifically to implement this technique, providing the client and server components needed to encode data into ACK packets and decode it on the other end. This specialization is what makes it the best fit for implementing ACK tunneling in practice. Other options describe different approaches or protocols. HTTP tunneling uses HTTP requests to carry data, which is a different tunneling method and not focused on embedding payloads in TCP ACKs. Flooding is a DoS tactic aimed at overwhelming a target with traffic, not establishing a covert command-and-control channel. ICMP protocol is a network-layer protocol that can be used for simple messaging or, in some cases, tunneling, but it’s not the dedicated tool designed for ACK tunneling.
