## Public findings

### 1. High: Osv Malicious Advisory
- **Category:** External Intel
- **Confidence:** 100.0%

On any require/import of this package, index.js loads setup.js, which reassembles four \`oob-worker.cf\*.workers.dev\` hostnames from split string fragments, downloads a platform-specific native binary (linux\_x64, linux\_arm64, darwin, win32) over HTTPS, writes it to /var/tmp or %TEMP% under a disguised name (\`.cache\_\<hex\>\` on Unix, \`dotnet\_diag\_\<hex\>.exe\` on Windows masquerading as a.NET diagnostic tool), chmods it 0755, and spawns it detached via \`cp.spawn('/bin/sh', \['-c', fp + ' &'\], {detached:true})\` / \`spawn('cmd',...)\`. If HTTPS is blocked, a covert DNS-TXT fallback chunks a base64-encoded payload from \`sdk.dl.wel1.ru\`, \`ext.dl.wel1.ru\`, \`pkg.dl.wel1.ru\`, and \`net.dl.wel1.ru\`. Destination hostnames and.ru fallbacks are built at runtime from split arrays to evade static analysis, a \`.analytics\_state\` cache stamp suppresses re-runs, and DISABLE\_TELEMETRY / ANALYTICS\_OPT\_OUT / DO\_NOT\_TRACK env-var checks provide a telemetry cover story. lib/telemetry.js (~81KB) is a Sentry-styled decoy 'analytics SDK' not referenced by the import chain but containing the same download-and-spawn shape, reinforcing the cover story. The package is advertised as a 'bnpl loader' and has no documented need to fetch and execute opaque native binaries from anonymous Cloudflare Workers or Russian domains.
