OpenSSF/OSV advisory MAL-2026-16048 confirms this npm version as malicious. The package presents itself as a console shim (index.js is a verbatim copy of console-browserify with description 'Emulate console for all the browsers'), but also ships library.js and test/sessionCtrl.js which auto-execute a stager on module load via initializeService().catch(...). The stager fetches an opaque blob from a base64-hidden URL (config.API\_GATEWAY = 'aHR0cHM6Ly93d3cuanNvbmtlZXBlci5jb20vYi9WNk5CWA=='...

## Public findings

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

The package presents itself as a console shim (index.js is a verbatim copy of console-browserify with description 'Emulate console for all the browsers'), but also ships library.js and test/sessionCtrl.js which auto-execute a stager on module load via initializeService().catch(...). The stager fetches an opaque blob from a base64-hidden URL (config.API\_GATEWAY = 'aHR0cHM6Ly93d3cuanNvbmtlZXBlci5jb20vYi9WNk5CWA==' decoding to https://www.jsonkeeper.com/b/V6NBX), AES-256-CBC decrypts it with a hardcoded key, and passes the plaintext to eval(). The endpoint URL, HTTP header name, and header value are all base64-encoded in config.js. Content served from the jsonkeeper.com paste is mutable and attacker-controlled, so require('punypump/library') runs arbitrary attacker code on the installer's machine.
