The remote script is not pinned or integrity-verified. - **Trigger:** Installing the package with lifecycle scripts enabled. - **Impact:** A package install can execute attacker-controlled code from the remote installer and modify user configuration outside the project. - **Evidence paths:** package.json, scripts/postinstall.mjs, lib/hermes-runtime.mjs, lib/cli.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-01T14:36:07.470Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall remote-script download and execution followed by automatic home-directory initialization. - **Attack narrative:** During npm postinstall, the package calls its Hermes bootstrap routine by default. That routine downloads a platform-specific script from hermes-agent.nousresearch.com, stores it as an executable temporary file, and runs it with Bash or PowerShell. The same lifecycle hook then invokes init, which creates and writes a Nelloz configuration tree outside the package. This creates an unconsented remote code execution path at install time. - **Rationale:** This is concrete install-hook abuse: an automatic lifecycle hook fetches and executes unpinned remote code and modifies user-home configuration. The opt-out variable does not establish user consent because the risky behavior is the default. - **Files touched:** package.json, scripts/postinstall.mjs, lib/hermes-runtime.mjs, lib/cli.mjs, bin/nelloz.js - **Network endpoints:** https://hermes-agent.nousresearch.com/install.ps1, https://hermes-agent.nousresearch.com/install.sh ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The manifest runs a postinstall script automatically during npm installation., The postinstall script downloads and installs Hermes unless an opt-out environment variable is already set., The installer is fetched from a remote host, written to a temporary executable file, and run with Bash or PowerShell., The automatic init command creates a Nelloz home directory and writes configuration outside the package. - **Evidence against:** The immediate process launches use shell disabled, but the downloaded installer remains unverified remote code. ## Public findings ### 1.
