The "Nth Room" case[1] (Korean: n번방 사건) is a criminal case involving blackmail, cybersex trafficking, and the spread of sexually exploitative videos via the Telegram app between 2018 and 2020 in South Korea.[2][3] A man nicknamed god god (later identified as Moon Hyung-wook, 문형욱) sold sexual exploitation videos on Telegram channels and groups.
A copycat crime, known as the "Doctor's Room", (박사방; 博士房; baksabang) was operated by a man using the screen name Doctor (박사; Baksa, later identified as Cho Ju-bin[4][5]), who is accused of blackmailing dozens of women, forcing them to take sexually exploitative videos, with some involving rape.[6][7][8][9]
The number of confirmed victims is at least 103, including 26 minors.[10][11] It was revealed that the victims' pictures were shared and sold to over 260,000 IDs (narrowed down to about 60,000 users, taking into consideration overlapping profiles)[12] and were paid for anonymously in cryptocurrency.
A Netflix documentary about the case, entitled Cyber Hell: Exposing An Internet Horror, was released in 2022.
