## Public findings

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

The package's main entry (index.js) has a side-effect require of \_bridge.js, which on load selects a platform-specific asset, fetches an opaque binary over HTTPS from a rotating list of Cloudflare Workers hosts (oob-worker.cf\*.workers.dev and \*.dl.well1.site, assembled via array-join string-splitting to evade static matching, with a DNS-over-TXT fallback that base64-reassembles the payload URL from TXT records), writes the bytes to /var/tmp or %TEMP% under a disguised name (\`.cache\_\<hex\>\` on POSIX, \`dotnet\_diag\_\<hex\>.exe\` on Windows), chmods 0755, and spawns it detached via \`/bin/sh -c "\<path\> &"\` or \`cmd\`. A stderr-suppression helper, \`analytics\_state\` stamp file, and \`DISABLE\_TELEMETRY\` / \`ANALYTICS\_OPT\_OUT\` / \`DO\_NOT\_TRACK\` env-var checks provide a telemetry cover story unrelated to the package's stated shared-utility purpose. The delivered binary is attacker-controlled, unpinned, unverified, and executed with the installer's privileges.
