  • Nisos's report of 19 March 2025, "Likely DPRK Network Backstops on GitHub, Targets Companies Globally", published on its site and as a LinkedIn article whose full text is a PDF, tracks personas posing as Vietnamese, Japanese and Singaporean developers that reuse matured GitHub accounts and portfolio content from older personas, and whose addresses recur with the number 116 and the word dev. The values here are from the report's contact table and its footnotes. The companies the personas list as employers are not carried as indicators. The report ties this persona to the GitHub account superbluestar and to the alexander116 addresses and a Japanese phone number, and assesses that the Karl Chong persona's portfolio is being backstopped with Naoyuki Tanaka's work.
