## Public findings

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

The postinstall lifecycle script runs ensurePlatformBinary, which when the optionalDependency install fails to populate the platform package falls back to fetching a.tgz over HTTPS from a hardcoded bare-IP endpoint, https://218.90.133.98:4443/onecode\_tgz/, with rejectUnauthorized:false disabling TLS certificate verification. The fetched archive is extracted with tar, the extracted binary is chmod 0755 and hardlinked into bin/.onecode, and that binary becomes the CLI invoked as \`onecode\`. No hash or signature verification is performed, the host is a bare IP rather than a publisher-owned domain, and the URL always constructs \`onecode-linux-x64-\<version\>.tgz\` regardless of the detected platform/arch. Whoever controls the endpoint at 218.90.133.98:4443 — or any on-path attacker, given TLS verification is disabled — can deliver arbitrary executable content to any installer whose optional platform dependency fails to install.
