- **Analysis source:** OSV Malicious Advisory (OpenSSF/OSV)

Trusted malware advisory MAL-2026-16123 identifies this version as malicious. Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory.

OpenSSF/OSV advisory MAL-2026-16123 confirms this npm version as malicious. The package impersonates picomatch (name 'pinochiomathm', description copied from picomatch, homepage pointing at github.com/micromatch/picomach). On require, lib/pinochiomathm.js reads lib/parse.ts.map, base64-decodes it into parsetmp.js, and requires it.

## Public findings

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

The package impersonates picomatch (name 'pinochiomathm', description copied from picomatch, homepage pointing at github.com/micromatch/picomach). On require, lib/pinochiomathm.js reads lib/parse.ts.map, base64-decodes it into parsetmp.js, and requires it. The decoded module performs an HTTP GET to https://www.jsonkeeper.com/b/V6NBX with a decoded 'x-secret-key' header, AES-256-CBC-decrypts the response using a hardcoded password, and passes the plaintext to eval(). A second disguised file lib/init.ts.map contains an additional base64-wrapped payload of the same shape. After execution the loader unlinks lib/parse.ts.map, parsetmp.js, lib/init.ts.map and config.js to remove the staged payload from disk. The result is arbitrary remote code execution in the installer's Node process, controlled by whoever edits the jsonkeeper paste, with anti-analysis evasion via sourcemap-filename disguise, base64+AES wrapping, and post-execution cleanup.
