Which tunneling method uses TCP packets with the ACK bit set to carry a backdoor application?

Explanation:
ACK tunneling relies on using TCP packets that have the ACK flag set to transmit a backdoor payload. In this approach, commands or data are carried within legitimate-looking TCP ACK traffic, so the backdoor can communicate over a normal TCP session without triggering obvious alarms. The ACK bit acts as a signaling mechanism within the TCP flow, making the channel difficult to distinguish from ordinary traffic because it doesn’t rely on a separate protocol like HTTP or ICMP. This stealthy use of TCP ACK packets for covert data exchange is what defines this tunneling method.
