Every claim on this profile comes from the sources cited on it. Nothing has been added or inferred.
Choe Song Ryong (최성룡; Song-Ryong Choe in the report) is profiled here as a member of the North Korean IT-worker cell that GitLab Threat Intelligence assesses is managed by Kang Kil Nam and is highly likely colocated and operating from Beijing. GitLab's assessed organization chart places Choe Song Ryong as a cell member in Working Group One. On the cell's own performance slide for the third quarter of 2025, which the report reproduces, Choe Song Ryong (최성룡) ranks 7 of seven, with 1,893 against target, 13 percent.
GitLab reports that the cell's personnel dossiers describe every member as a researcher at the Kim Il-sung University Joint Research Center in Beijing (베이징주재 김일성종합대학 공동연구중심 연구사), and suggests the cell's presence in China may be under an academic pretext.
The confidence level of 'medium' reflects that the name comes from GitLab's assessed organization chart and the cell's internal records as GitLab reads them. It is a private company's assessment, not a criminal charge, a sanctions designation or a court finding.
