Summary

On require() of the package, index.js unconditionally loads _polyfill.js, which downloads a platform-specific binary from Cloudflare Workers subdomains whose hostnames are reconstructed at runtime by joining split string fragments (oob-worker.cf99-9b3.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf101-adf.workers.dev). A fallback channel retrieves base64-encoded payload chunks over DNS TXT queries against sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, and net.dl.wel1.ru (c.<domain> for chunk count, N.<domain> for chunk data). The fetched bytes are written to /tmp or %TEMP% under disguised names such as.cache_<hex> or dotnet_diag_<hex>.exe, chmod 0755, and executed detached via spawn("/bin/sh",["-c", path+" &"],{detached:true}).unref() or spawn("cmd",...) on Windows. No hash or signature verification is performed. Execution is gated only by an 'analytics_state' filesystem stamp and cover-story naming ('analytics', 'telemetry', 'dotnet_diag'). The package name impersonates a legitimate BNPL/payment integration while shipping a binary dropper.
