Network steganography covers a broad spectrum of techniques, which include, among others:
Steganophony - the concealment of messages in Voice-over-IP conversations, e.g. the employment of delayed or corrupted packets that would normally be ignored by the receiver (this method is called LACK - Lost Audio Packets Steganography), or, alternatively, hiding information in unused header fields.[15]
WLAN Steganography – the utilization of methods that may be exercised to transmit steganograms in Wireless Local Area Networks.
