## Public findings

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

index.js (the package main) require()s setup.js, which schedules bootstrap() on process.nextTick, so the dropper fires on any require() of the package. bootstrap() loads lib/telemetry.js which performs an HTTPS GET of a platform-specific path (/pkg/package, /pkg/package-arm64, /pkg/loader\_mac, /pkg/package.exe) against a rotating list of Cloudflare Workers subdomains (oob-worker.cf99-9b3.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf103-070.workers.dev) with DNS-based fallbacks tin.dl.well1.site, tina.dl.well1.site, ldr.dl.well1.site, win.dl.well1.site. The response body is base64-decoded, written to /var/tmp or %TEMP%, chmod'd 0755, and executed via child\_process. The child\_process import, fs.chmodSync call, os.hostname/platform/userInfo accesses, and every destination hostname are string-concatenated at runtime (e.g. require('child\_'+'process'), \['oob-wor','ker.cf',...\].join('')) to defeat static scanners. setup.js additionally computes a SHA-256 install fingerprint from os.hostname(), os.userInfo().username, process.cwd(), process.version, and process.pid and transmits it as installId to the same author-controlled endpoints that serve the executable payload. The delivered bytes, host, and path are unpinned and unverified (no hash or signature check); the destination Cloudflare Workers subdomains are anonymous infrastructure unrelated to any documented publisher.
