Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Installing the package automatically launches a bundled native program to install agent skills. This mutates a broad, foreign coding-agent control surface without an explicit user command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-17T18:15:22.008Z - **Finished:** 2026-09-17T18:16:16.819Z - **Download time:** 506 ms - **Static scan time:** 125 ms - **AI review time:** 54179 ms - **Total time:** 54811 ms The recorded confidence comes from the underlying analysis.

This mutates a broad, foreign coding-agent control surface without an explicit user command. - **Trigger:** npm installation runs postinstall. - **Impact:** Agent behavior can be changed by package-provided skills before the user invokes the CLI. - **Evidence paths:** package.json, scripts/postinstall.js, bin/nanocorp.js - **Review source:** ai\_review - **Reviewed:** 2026-09-17T18:16:16.819Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** A hidden lifecycle hook launches a native skill installer. - **Attack narrative:** During npm installation, the postinstall hook silently calls the package launcher with skills install. The launcher changes permissions on a platform-specific bundled binary and executes it. This creates an automatic path for package-controlled native code to install skills into coding-agent environments, without requiring the user to run a setup command. - **Rationale:** This is unconsented postinstall mutation of a broad AI-agent control surface, executed through opaque bundled native code. The opt-out does not establish prior consent for the default installation behavior. - **Files touched:** scripts/postinstall.js, bin/nanocorp.js, vendor/nanocorp-darwin-amd64, vendor/nanocorp-darwin-arm64, vendor/nanocorp-linux-amd64, vendor/nanocorp-linux-arm64 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The manifest automatically runs a postinstall hook., The hook invokes the CLI with the skills install command without user interaction., The launcher makes a bundled native binary executable and runs it with those arguments., The hook suppresses output and errors, making the mutation nontransparent during installation. - **Evidence against:** The hook provides an environment-variable opt-out., No network endpoint is present in the reviewed JavaScript sources. ## Affected versions and remediation This report applies to nanocorp@0.3.2. - Avoid installing nanocorp@0.3.2. 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.
