From an article about Zheng Xiaoqing, an American convicted of spying for China:
According to a Department of Justice (DOJ) indictment, the US citizen hid confidential files stolen from his employers in the binary code of a digital photograph of a sunset, which Mr Zheng then mailed to himself.
EDITED TO ADD (2/14): The 2018 criminal complaint has a “Steganography Egress Summary” that spends about 2 pages describing Zheng’s steps (p 6-7). That document has some really good detail.
