On Windows it also creates a hidden launcher and desktop shortcut. - **Trigger:** npm postinstall - **Impact:** An npm install can install and configure an external AI agent and create persistent user-facing launch artifacts without an explicit command. - **Evidence paths:** package.json, scripts/postinstall.mjs, lib/hermes-runtime.mjs, lib/cli.mjs, lib/desktop-app.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-03T15:36:34.647Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote installer execution and user-home agent setup - **Attack narrative:** During npm installation, postinstall calls ensureHermesInstalled. If Hermes is absent, the package downloads a shell or PowerShell installer from hermes-agent.nousresearch.com, writes it to a temporary executable file, and runs it. The same hook initializes configuration and secrets in the user's Nelloz home; on Windows it creates a hidden PowerShell launcher and desktop shortcut. These actions occur without an explicit user command. - **Rationale:** The automatic lifecycle hook executes a remotely fetched installer and mutates a foreign AI-agent environment plus user-home and desktop state. This meets the install-hook abuse blocking policy. - **Files touched:** scripts/postinstall.mjs, lib/hermes-runtime.mjs, lib/cli.mjs, lib/desktop-app.mjs, ~/.hermes, ~/.nelloz, %LOCALAPPDATA%/Nelloz, Windows Desktop - **Network endpoints:** hermes-agent.nousresearch.com ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The package declares an automatic postinstall hook., Postinstall downloads and executes an unauthenticated remote Hermes installer., Postinstall creates Nelloz configuration under the user's home and a hidden Windows desktop launcher., This is an unconsented install-time mutation of an external AI-agent environment. - **Evidence against:** No runtime dependency on another release of nelloz was found., The remote installer is invoked with an explicit argument list rather than a shell string. ## Public findings ### 1.
