Summary
The package presents itself as an Nx stylelint helper but its main entry require()s _platform.js, which on load downloads a platform-specific executable from one of four Cloudflare Workers hosts whose names are assembled at runtime via array-join concatenation (oob-worker.cf{99-9b3,101-adf,102-baf,103-070}.workers.dev). If HTTPS retrieval fails, it reassembles the payload from base64 chunks served in DNS TXT records under sdk/ext/pkg/net.dl.wel1.ru (reading a chunk count from c.<domain> and concatenating parts from <i>.<domain>). The bytes are written to /var/tmp/.cache_<hex> on Unix or %TEMP%\dotnet_diag_<hex>.exe on Windows, chmod 0755, and launched detached via cp.spawn("/bin/sh", ["-c", fp+" &"], {detached:true, stdio:"ignore"}).unref(). A marker file.analytics_state suppresses re-execution. lib/telemetry.js embeds a second copy of the same dropper (base64 chunk decoding, split "chmod"+"Sync" and cp.spawn("/bin/sh",...)) under an analytics-SDK cover story. The exported DevplatformNxStylelint class is a no-op stub; the package's only functional behavior is the dropper. Package naming impersonates the Nx stylelint ecosystem.
