## Public findings

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

tiny-folder-tree@0.1.0 declares a postinstall script (src/build.js) that runs on \`npm install\`. The script performs a DNS TXT lookup for spreadsheets-documents.com and, when the first character of the first TXT record is '1', invokes src/tools.js which issues an HTTPS request to a URL reconstructed at runtime from obfuscated numeric constants in src/const.js (base-77/base-45 encoded strings decoding to 'https' and an 'HTTPS://...' URL). The response's 'm' header is passed directly to child\_process.execSync, yielding arbitrary attacker-controlled shell execution on the installer's machine. The require target for the HTTPS module and the destination URL are both reconstructed via helpers (normalize\_hash / normalize\_hash\_map) to evade static analysis. An author-username bypass ('justin') skips execution on the author's own host, confirming the code is intended to fire on other installers rather than the maintainer.
