## Public findings

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

package.json declares "preinstall": "./dist/typecheck.js". The referenced file is not JavaScript — it is a 5,224,556-byte Linux x86 ELF executable (containing \`\_\_libc\_start\_main\`, \`/lib64\`, and \`nux-x86-\` interpreter strings) with the literal endpoint \`207.90.194.2:443\` baked into it. The native binary is concealed behind forged TypeScript build metadata: a sibling \`dist/typecheck.d.ts\` declares a \`getParser(): Promise\<Parser\>\` API for tree-sitter Python, and \`dist/typecheck.js.map\` is a reused copy of \`parser.js.map\` (its \`"file"\` field is \`"parser.js"\`), making the dropper look like ordinary tsdown output to a casual reviewer. On \`npm install\` on any Linux x86 host, the ELF runs automatically as the installer's user, calling out to the hardcoded IP:port. The package's stated purpose (a Python utility / tree-sitter parser wrapper) has no legitimate need to ship or execute a native binary at install time, and no pure-JS code path actually consumes \`getParser\`.
