Hover Lab

Hover Lab, also known as Garo Sero Research Institute (Korean: 가로세로연구소), is a South Korean YouTube channel and think tank.

Hover Lab is widely considered to promote far-right political views, and has promoted misleading or fabricated information about celebrities, politicians, and politics on a number of occasions. It and its members have been found liable or guilty of a number of defamation lawsuits and criminal complaints. For example, its members lost cases brought by current South Korean president Lee Jae Myung and politician Cho Kuk. The organization is also currently facing several lawsuits and complaints, including several from YouTuber Tzuyang and actor Kim Soo-hyun.

The organization was founded by reporter and lawyer and politician Kang Yongseok. Kang's law license was suspended until 2030 after he was convicted of violating election law. Journalist was also a long-time contributor, until 2023, when he committed suicide after being convicted of sexual assault.
