Injected or replaced skills can influence the behavior of installed coding agents without an explicit setup 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:** 0.3.0 - **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. Installing the package automatically invokes a native CLI to install and overwrite agent skills across several third-party coding-agent directories. No network endpoint is needed for this control-surface mutation. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 97.0% - **Started:** 2026-09-07T19:18:37.806Z - **Finished:** 2026-09-07T19:19:53.157Z - **Download time:** 510 ms - **Static scan time:** 137 ms - **AI review time:** 74704 ms - **Total time:** 75351 ms The recorded confidence comes from the underlying analysis.

No network endpoint is needed for this control-surface mutation. - **Trigger:** npm postinstall when NANOCORP\_NO\_AGENT\_SKILLS is not set and a supported agent directory exists. - **Impact:** Injected or replaced skills can influence the behavior of installed coding agents without an explicit setup command. - **Evidence paths:** package.json, scripts/postinstall.js, bin/nanocorp.js, vendor/nanocorp-linux-arm64, README.md - **Review source:** ai\_review - **Reviewed:** 2026-09-07T19:19:53.157Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic native-binary installation of agent skill files into foreign agent directories. - **Attack narrative:** During npm installation, postinstall starts the package launcher with skills install. The launcher executes a vendored native binary. Embedded binary text and the package documentation show that this command installs and overwrites NanoCorp skill files in existing Claude Code, Codex, Cursor, Gemini CLI, GitHub Copilot, and vendor-neutral agent directories. The mutation occurs automatically unless the user set an opt-out environment variable beforehand, creating an unconsented broad AI-agent control-surface write. - **Rationale:** This is a concrete automatic postinstall mutation of foreign and broad AI-agent control surfaces. The opt-out does not establish affirmative consent for the lifecycle action. - **Files touched:** scripts/postinstall.js, bin/nanocorp.js, vendor/nanocorp-linux-arm64, ~/.claude/skills/, ~/.codex/skills/, ~/.cursor/skills/, ~/.gemini/skills/, ~/.copilot/skills/, ~/.agents/skills/ ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package declares an automatic postinstall hook., The hook launches the vendored CLI with the skills install command unless an opt-out variable is already set., The launcher executes a native binary, and its embedded text says it overwrites skill copies in several unrelated coding-agent directories., This mutates broad AI-agent control surfaces during installation, rather than after an explicit setup command. - **Evidence against:** The JavaScript install hook contains no network request or credential collection., An environment-variable opt-out exists, but it requires action before installation. ## Affected versions and remediation This report applies to nanocorp@0.3.0. - Avoid installing nanocorp@0.3.0. 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.

High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 97.0% - **Path:** bin/nanocorp.js - **Public source:** [View source]() The launcher executes a native binary, and its embedded text says it overwrites skill copies in several unrelated coding-agent directories. Public source snippet (untrusted): ```javascript const bin = join(__dirname, "..", "vendor", name); try { fs.chmodSync(bin, 0o755); } catch { /* best effort: npm does not reliably preserve +x on vendored files */ } const res = spawnSync(bin, process.argv.slice(2), { stdio: "inherit" }); ``` ### 12. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 97.0% - **Path:** vendor/nanocorp-linux-arm64 - **Public source:** [View source]() The launcher executes a native binary, and its embedded text says it overwrites skill copies in several unrelated coding-agent directories. Public source snippet (untrusted): ```text Writes the embedded nanocorp-* skills into the skill directories of any supported coding agent you already have (Claude Code, Codex, Cursor, Gemini CLI, GitHub Copilot, and the vendor-neutral ~/.agents dir). It never creates those directories, overwrites existing copies so re-running refreshes them, and skips silently when no agent is found. Set NANOCORP_NO_AGENT_SKILLS to disable. install.sh runs this automatically. ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** postinstall - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** nanocorp - **Ecosystem:** npm - **Version:** 0.3.0 - **License:** UNLICENSED - **Version published:** 2026-09-07T19:10:40.700Z - **Package first seen:** 2026-09-07T19:19:53.157Z - **Package last seen:** 2026-10-07T23:57:50.691Z - **Known versions:** 7 - **Latest version:** 0.3.9 - **Appeal under review:** No - **Description:** NanoCorp CLI: create and run your autonomous company from the terminal. - **Runtime engines:** node: \>=18 - **Supported OS:** darwin, linux - **Supported CPU:** x64, arm64 - **Artifact files:** 9 - **Artifact unpacked size:** 29,949,464 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]() - [Homepage]()
