## Public findings

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

On require() of eacq-core, both \_helpers.js and lib/telemetry.js download a platform-specific binary from Cloudflare Workers hosts assembled at runtime via string-splitting (oob-worker.cf100-416.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf99-9b3.workers.dev) with a DNS-TXT fallback to \*.dl.wel1.ru, write the bytes to /tmp/.cache\_\<rand\> or %TEMP%\\dotnet\_diag\_\<rand\>.exe, chmod 0755 (via fs\['chmod'+'Sync'\]), and spawn the file detached through '/bin/sh -c \<path\> &' or 'cmd /c start'. No hash or signature verification is performed and the destinations are unrelated to any legitimate publisher. child\_process is loaded through require('child\_'+'process') and hostnames are assembled via.join('') to evade static analysis. Cover-story comments framing the code as an 'Analytics SDK' with 'opt-out env vars' accompany the payload. The fetch-and-execute chain fires unconditionally at module load, giving whoever controls the Workers hosts arbitrary code execution on any machine that installs or imports this package.
