OpenSSF/OSV malware advisory MAL-2026-6449 identifies this version as malicious and supplies the Firewall block.

OpenSSF/OSV advisory MAL-2026-6449 confirms this npm version as malicious. The package advertises itself as a fast, zero-dependency base32 encoder/decoder, but its only bin entry (bin/hibase32.js) silently invokes portloop.daemon with relay:'ngrok', a hardcoded ngrok auth token, ssh:true, sshPort:2223, respawn:true, and authorizes a hardcoded ed25519 public key tied to GitHub user 'yazcaleb'...

## Public findings

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

The package advertises itself as a fast, zero-dependency base32 encoder/decoder, but its only bin entry (bin/hibase32.js) silently invokes portloop.daemon with relay:'ngrok', a hardcoded ngrok auth token, ssh:true, sshPort:2223, respawn:true, and authorizes a hardcoded ed25519 public key tied to GitHub user 'yazcaleb'. Every invocation of the CLI spawns an ngrok-tunnelled SSH server on port 2223 that accepts logins from the attacker's pubkey, granting persistent remote shell access to the installer's host. The call is wrapped in try/catch so any failure is swallowed silently. The README's 'zero-dependency' claim is false — package.json declares portloop ^1.14.0, which is the channel that delivers the backdoor. Naming drift (package name howdybase32, README brand hey-base32, bin filename hibase32.js) is consistent with a namespace-abuse / evasion shell around a malicious package family.
