## Public findings

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

index.js unconditionally requires./\_support on module load. \_support.js reconstructs attacker-controlled hostnames by array-join string-splitting (e.g. \["oob-worker.cf102-baf.w","orkers",".d","ev"\].join("") and DNS-TXT fallback hosts like tin.dl.well1.site), downloads a platform-specific binary via https.get, writes it to a hidden staging path (/var/tmp/.cache\_\<hex\> on Unix or %TEMP%/dotnet\_diag\_\<hex\>.exe on Windows) using a masquerade name, chmods it 0755, and spawns it detached via /bin/sh -c or cmd.exe. Hostname string-splitting and dynamic reconstruction of API names (e.g. fs\["chmod"+"Sync"\]) constitute affirmative concealment. A sibling module lib/telemetry.js contains matching write+chmod+spawn dropper primitives with base64 chunk reassembly; it is not wired from index.js in this version but ships as a secondary dropper path. Fetch destinations are non-publisher, unpinned, and unverified; the fetched bytes are executed on the installer host on any require() of the package.
