NSHC frames its SectorA01 custom proxy utility analysis around the difficulty of moving from threat-group attribution to nation-state attribution. The excerpt warns that custom malware, stolen code, repackaging, recreated functions, and false-flag strings or metadata can all distort conclusions if analysts rely on tooling alone. It says confidence should come from comparing tactics, techniques, procedures, code protectors, functions, and algorithms across multiple trusted events. SectorA01 is described as continuing attacks against financial sectors worldwide, but the excerpt does not support a stronger country-level attribution.
