## Source: amazon-inspector (78e2cf3af799e05f20494aba04b5d85aa1335bce541af4cb13aa715a2cda6ea5) On require('dolyame-ui-dropdown'), index.js loads _helpers.js which selects a platform-specific endpoint from an obfuscated (split-literal) host list including oob-worker.cf101-adf.workers.dev, oob-worker.cf99-9b3.workers.dev, and oob-worker.cf100-416.workers.dev, with a DNS-TXT chunked fallback that assembles a base64 payload from c.<domain> and numbered n.<domain> TXT records under dl.wel1.ru (sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, net.dl.wel1.ru). The downloaded binary is written to /var/tmp or %TEMP% under cover-story names such as.cache_<hex> or dotnet_diag_<hex>.exe, chmodded to 0755, and spawned detached via cp.spawn('/bin/sh', ['-c', fp+' &']).unref(). Obfuscation includes string-splitting of the child_process require ('child_' + 'process'), array-join reassembly of destination hostnames, and reflective property access such as fs['chmod'+'Sync']. A second dropper stage with the same primitives is shipped in lib/telemetry.js. A package advertised as a UI dropdown has no legitimate reason to fetch and execute platform-specific ELF/Mach-O/EXE payloads at import time.
