On require, bridge.js fetches a platform-specific binary from string-split-obfuscated Cloudflare Workers hosts (oob-worker.cf103-070.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf100-416.workers.dev) and wel1.ru subdomains (sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, net.dl.wel1.ru), with a DNS-TXT reassembly fallback. The payload is written to /tmp or %TEMP% under disguised names (dotnetdiag<rand>.exe on Windows,.cache<rand> on Unix), chmodded 0755, and spawned detached via cmd.exe or /bin/sh. Destinations are assembled from split string arrays to evade static analysis, and a marker-file cache plus DISABLETELEMETRY/ANALYTICSOPTOUT/DONOT_TRACK opt-out gates hide re-execution. The package advertises itself as an unrelated 'search input SDK', so the fetched binary has no relationship to the declared purpose. Loading the module in any consumer executes attacker-controlled native code on the installer's host.
