## Verdict summary
**Soft block: AI-agent control surface** — Warn by default; block when configured. A remote installer gains code execution and can install or configure the Hermes AI agent on the user's machine.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Warn by default
- **Public report status:** Published
- **Threat category:** Soft block: AI-agent control surface
- **Selected version:** 0.48.2
- **Selected version is latest:** Yes
- **Analysis source:** AI Security Review (lpm-firewall-ai)

LPM flags this version as an AI-agent control-surface risk. Installing the package downloads and executes a third-party Hermes installer, then initializes Nelloz configuration. This mutates a foreign AI-agent environment without an explicit user command.

## Security analysis

### Published attack-surface review

- **Summary:** Installing the package downloads and executes a third-party Hermes installer, then initializes Nelloz configuration. This mutates a foreign AI-agent environment without an explicit user command.

- **Trigger:** npm postinstall during package installation.

- **Impact:** A remote installer gains code execution and can install or configure the Hermes AI agent on the user's machine.

- **Evidence paths:** package.json, scripts/postinstall.mjs, lib/hermes-runtime.mjs, lib/cli.mjs

- **Review source:** ai\_review

- **Reviewed:** 2026-08-26T15:48:38.181Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** Remote shell-script download and execution followed by automatic initialization.

- **Attack narrative:** During npm installation, the postinstall hook calls ensureHermesInstalled by default. That function fetches a platform-specific installer from hermes-agent.nousresearch.com, writes it to a temporary file, and runs it with bash or PowerShell. The hook then invokes nelloz init, which creates user configuration under the default Nelloz home. This is unconsented install-time execution and setup of a separate AI-agent control surface.

- **Rationale:** The package performs unverified remote code execution during postinstall to install a separate Hermes AI agent. This is a concrete unconsented lifecycle mutation of a foreign AI-agent control surface.

- **Files touched:** scripts/postinstall.mjs, lib/hermes-runtime.mjs, bin/nelloz.js, dist/payload/config/omni.env.example

- **Network endpoints:** https://hermes-agent.nousresearch.com/install.ps1, https://hermes-agent.nousresearch.com/install.sh

### Review decision

- **Verdict:** Malicious

- **Confidence:** 98.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** The postinstall hook automatically installs Hermes unless an environment opt-out is set., It downloads a remote installer and executes it with bash or PowerShell without integrity verification., The same install hook runs the package init command, which creates default user configuration.

- **Evidence against:** The displayed process calls set shell to false., The package's own init writes only its Nelloz configuration path.
