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 reached this persona through nickdev0118, which co-authored commits with AnacondaDev0120, a previously identified likely DPRK IT-worker account, and found it listed on the Huy Diep website, whose photographs it shows to be the persona's head pasted onto stock images. The report states the persona appears to have been employed as a software engineer at a Japanese consulting company since September 2023. The Telegram handle superbluestar is one the report attributes jointly to this persona, Naoyuki Tanaka and Shaorun Zhang.

The report attributes the superbluestar username jointly to this persona and Naoyuki Tanaka, and shows the persona's linktr.ee photograph to be an advertising image of another person. The repository shaorun-dev116.github.io, held by github.com/kamaalsultan, is where the report shows the persona being built. The report gives the phone number as 323 412 8387 with no country code; 323 is a Los Angeles area code, so it is carried as a United States number.
