An agent may be induced to open a browser flow and install persistent commands and instructions into foreign global agent control surfaces without a direct user request. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.19.0 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. LPM flags this version as an AI-agent control-surface risk. A global npm install emits instructions intended to make an AI agent immediately start browser-based setup. The follow-on setup can install persistent guidance and command hooks into global AI-agent configuration. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-09-15T06:59:33.269Z - **Finished:** 2026-09-15T07:00:54.930Z - **Download time:** 503 ms - **Static scan time:** 2063 ms - **AI review time:** 79093 ms - **Total time:** 81661 ms The recorded confidence comes from the underlying analysis.

The follow-on setup can install persistent guidance and command hooks into global AI-agent configuration. - **Trigger:** A global npm installation whose postinstall output is read by an AI agent. - **Impact:** An agent may be induced to open a browser flow and install persistent commands and instructions into foreign global agent control surfaces without a direct user request. - **Evidence paths:** package.json, scripts/postinstall.mjs, dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-15T07:00:54.930Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Lifecycle-driven AI-agent coercion followed by global agent configuration and hook setup. - **Attack narrative:** Installing the package globally runs postinstall. That script addresses any AI agent reading the installer output and tells it to run browser-based setup immediately rather than present the command to the user. The setup path opens a browser, can keep a detached process waiting for completion, and is built to write global Claude and Codex instruction and hook files. This turns a package lifecycle message into a chain that can alter an AI agent's persistent control surface. - **Rationale:** The package uses an automatic install hook to socially engineer an AI agent into a follow-on setup flow that persists commands and instructions in global agent configuration. This is a concrete lifecycle-driven AI control-surface hijack risk despite the postinstall script not writing those files itself. - **Files touched:** scripts/postinstall.mjs, dist/index.js, ~/.claude/CLAUDE.md, ~/.claude/settings.json, ~/.codex/AGENTS.md, ~/.codex/hooks.json - **Network endpoints:** memgineering.com, https://api.memgineering.com ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The install lifecycle runs a package script after installation., The postinstall output directly instructs an AI agent to run setup immediately instead of asking the user., The instructed setup opens a browser flow and can continue in a detached child process., Setup writes guidance and hooks into global Claude and Codex control files. - **Evidence against:** The postinstall script itself only prints on global installs and does not directly write agent files., The API client uses a package-aligned default host; no environment harvesting was confirmed. ## Affected versions and remediation This report applies to memgineering@0.19.0. - Avoid installing memgineering@0.19.0. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
