Changes the behavior and instruction context of Claude, Cursor, and GitHub Copilot in projects that already contain those control surfaces. - **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:** 0.1.73 - **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 runs code that changes AI-agent instruction files in the consuming project. It can append a Claude reference, create a Cursor rule, and append GitHub Copilot instructions. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-13T14:34:16.960Z - **Finished:** 2026-09-13T14:34:58.653Z - **Download time:** 505 ms - **Static scan time:** 508 ms - **AI review time:** 40679 ms - **Total time:** 41693 ms The recorded confidence comes from the underlying analysis.

It can append a Claude reference, create a Cursor rule, and append GitHub Copilot instructions. - **Trigger:** npm installation runs the postinstall lifecycle hook. - **Impact:** Changes the behavior and instruction context of Claude, Cursor, and GitHub Copilot in projects that already contain those control surfaces. - **Evidence paths:** package.json, scripts/postinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-09-13T14:34:58.653Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic writes to consumer-project AI-agent configuration files. - **Attack narrative:** On installation, package.json invokes scripts/postinstall.js. The script uses the installer working directory as the consumer project root, then conditionally appends a reference to CLAUDE.md, creates .cursor/rules/lds.mdc, and appends content to .github/copilot-instructions.md. These are foreign AI-agent control surfaces and are altered without an explicit setup command or user confirmation. - **Rationale:** This package has a concrete automatic postinstall chain that mutates multiple consumer-project AI-agent instruction surfaces. The absence of exfiltration does not remove the unconsented install-time control-surface modification. - **Files touched:** CLAUDE.md, .cursor/rules/lds.mdc, .github/copilot-instructions.md, scripts/postinstall.js ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The manifest automatically runs a postinstall script., The install script modifies a consumer project's Claude instructions file., The install script creates Cursor rules and appends GitHub Copilot instructions without an explicit user command. - **Evidence against:** The script contains no network, credential-harvesting, shell-execution, or self-dependency behavior., The runtime bundle appears to be a React UI library and does not contain the install-time file-writing logic. ## Affected versions and remediation This report applies to @lawkit/ui@0.1.73. - Avoid installing @lawkit/ui@0.1.73. 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.
