MAL-2026-13194 Malicious code in dolyame-ui-textarea (npm)

The package's main entry unconditionally requires./loader.js on load. loader.js assembles mirror hostnames from split string arrays to build a set of .workers.dev endpoints (e.g. oob-worker.cf10x-.workers.dev), fetches a platform-specific binary over https.get, and falls back to base64-chunked DNS TXT records under *.dl.wel1.ru subdomains when the HTTP mirrors are unavailable. The fetched bytes are written to /var/tmp or %TEMP% under masquerade filenames (.cache<rand> on Unix, dotnet_diag<rand>.exe on Windows), chmodded to 0755, and spawned detached via /bin/sh -c or cmd.exe with stdio ignored and unref(). Environment variables named DISABLE_TELEMETRY / ANALYTICS_OPT_OUT / DO_NOT_TRACK and a cache filename.analytics_state disguise the dropper as telemetry. A second variant of the same dropper (base64 chunk assembly, chmod 0755 via dynamic property name fs['chmod'+'Sync'], detached /bin/sh spawn) is bundled in lib/telemetry.js under an 'analytics SDK' cover story. The package name resembles a UI component library but ships no textarea functionality; its only on-load behavior is the drop-and-execute chain.
