The package is published under a name suggesting a React UI text component, but its main entry (index.js) require()s./init on module load, which acts as a binary dropper. init.js reconstructs C2 hostnames at runtime from string-split arrays (resolving to oob-worker.cf*.workers.dev and *.dl.wel1.ru), downloads a platform-specific payload over HTTPS with a DNS-TXT base64 fallback channel (chunk-count read from c.<domain>, chunks reassembled from N.<domain>), writes the payload to /tmp (Unix) or %TEMP% (Windows) under decoy names such as.cache<hex> and dotnetdiag_<hex>.exe, chmods it to 0755, and spawns it detached via /bin/sh -c or cmd. A second dropper implementation in lib/telemetry.js, cover-labeled as an 'Analytics SDK', base64-decodes an embedded payload buffer, uses bracket-property obfuscation to hide chmodSync, and spawns the dropped file via /bin/sh -c. No published functionality relates to a UI text component; the delivered code, its obfuscation, and its execution path have no benign explanation.
