Modified copy of Level Infinite's official https://na-webassets.playerinfinite.com/comm/nikke_launcher/assets/images.7fec4c32.js (4,358 bytes, ETag 481e9b5ab8fb93406bf31980b53e0578), Last-Modified 2026-09-27 06:41:57 GMT, served until Level Infinite replaced it on 2026-11-03 at 17:21 GMT. It loads https://insightjs.com/l.js?f=images. The added code decodes the loader URL from a Uint32Array with TextDecoder and loads it in the NIKKE PC launcher's embedded browser (tbs_browser.exe), falling back to insightjs.org. l.js then made the launcher download and run the LuaJIT agent insight.bundle (SHA-256 cc0ad05bfe85940a6067b3a72c182d3953339129206634141926d5d0b35973ec). Recovered from a victim's launcher cache (tbs_cache\Cache). Write-up and IOCs: https://gist.github.com/MotherSphere/d6c049a09ba8ac3085c51ee9df24a4e5
