Read on 12 September 2026 from a listing on the pipu.cc marketplace whose product description is this curriculum vitae and whose product image is the photograph shown. The listing went up on 1 July 2025 from a seller account named after the CV's subject, one of 1,882 such listings posted between 26 June and 2 July 2025 that between them hold about 1,860 CVs. The address james.sungsoo.choi@outlook.com is what tied the listing to this site's index: it appears in DTEX's i3 Threat Advisory email-indicator appendix, which DTEX itself says is not evidence of a confirmed attribution and may list addresses whose real owners are uninvolved. Every other value here is read from the listing itself and is the listing's own claim. A CV in this set may be a real person's stolen document, so the name on it, and the employers and schools it lists, may belong to someone with no part in the operation.

Per DTEX's own advisory text: these IOCs are NOT indicative of a confirmed North-Korea-attributed hack — they may have associations with IT-worker operations and require further investigation if observed in your environment. Any connection to actual persons may be deliberate (an operator using a real person's identity) or incidental, and the actual owner of an email account listed here may be unaware their address is associated with this IOC list. Do not treat presence on this list as proof of wrongdoing by the account holder.
