It can silently add package-provided skills to third-party coding-agent directories without an explicit user command. - **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:** 0.3.3 - **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. Installing the package automatically runs an opaque bundled skill installer. It targets identifiers associated with multiple coding-agent control surfaces. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-09-20T06:55:20.066Z - **Finished:** 2026-09-20T06:56:41.561Z - **Download time:** 770 ms - **Static scan time:** 111 ms - **AI review time:** 80613 ms - **Total time:** 81495 ms The recorded confidence comes from the underlying analysis.

It targets identifiers associated with multiple coding-agent control surfaces. - **Trigger:** npm post-install execution - **Impact:** It can silently add package-provided skills to third-party coding-agent directories without an explicit user command. - **Evidence paths:** package.json, scripts/postinstall.js, bin/nanocorp.js, vendor/nanocorp-darwin-arm64 - **Review source:** ai\_review - **Reviewed:** 2026-09-20T06:56:41.561Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The lifecycle hook invokes the package launcher with "skills install --quiet"; the launcher executes a vendored native binary. - **Attack narrative:** On installation, the package runs a post-install script that silently calls its vendored native executable to install skills. The binary contains markers for multiple coding-agent directories, so the automatic action reaches a broad foreign agent control surface rather than merely setting up the CLI. The opt-out requires pre-existing user knowledge and does not make this installation consensual. - **Rationale:** This is unconsented post-install mutation of third-party AI-agent control surfaces through an opaque native binary. The automatic, quiet execution meets the install-control-surface blocking policy. - **Files touched:** .claude, .cursor, .gemini, .codex ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package registers an automatic post-install hook., The post-install hook launches the bundled executable with a quiet skill-install command unless an environment opt-out is already set., The bundled executable contains identifiers for several third-party coding-agent directories, indicating a broad agent control surface., The hook suppresses child output and swallows failures, making the automatic mutation non-interactive and less visible. - **Evidence against:** No runtime dependency on the package's own name is declared., The hook has an environment-variable opt-out, but this does not establish installer consent. ## Affected versions and remediation This report applies to nanocorp@0.3.3. - Avoid installing nanocorp@0.3.3. 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.
