The package injects package-selected guidance into tools that can influence developer and agent behavior. - **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:** 0.1.72 - **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 alters existing project AI-agent instruction files. It can append to CLAUDE.md and Copilot instructions or create a Cursor rule. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-12T09:45:59.273Z - **Finished:** 2026-09-12T09:46:45.312Z - **Download time:** 773 ms - **Static scan time:** 550 ms - **AI review time:** 44715 ms - **Total time:** 46039 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Installing the package automatically alters existing project AI-agent instruction files. It can append to CLAUDE.md and Copilot instructions or create a Cursor rule. - **Trigger:** npm installation runs the postinstall hook. - **Impact:** The package injects package-selected guidance into tools that can influence developer and agent behavior. - **Evidence paths:** package.json, scripts/postinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-09-12T09:46:45.312Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic writes to project AI-agent control surfaces. - **Attack narrative:** On installation, package.json launches scripts/postinstall.js. The script uses the consumer project's current directory, appends a reference to its own instructions into CLAUDE.md, creates a Cursor rule when that rules directory exists, and appends to GitHub Copilot instructions when present. These unconsented lifecycle changes target external AI-agent control surfaces. - **Rationale:** This is an automatic postinstall mutation of multiple pre-existing project AI-agent control surfaces. Although no exfiltration or network activity was found, the behavior meets the blocking policy for unconsented broad agent-control modification. - **Files touched:** scripts/postinstall.js, CLAUDE.md, .cursor/rules/lds.mdc, .github/copilot-instructions.md ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** Installation automatically runs a package script., The script appends a package instruction reference to an existing project CLAUDE.md., The script writes or appends instructions into existing Cursor and GitHub Copilot control files. - **Evidence against:** No outbound network, command execution, or credential collection was found in the inspected lifecycle script., The runtime bundle appears to be a React UI library and did not show additional install-time behavior. ## Affected versions and remediation This report applies to @lawkit/ui@0.1.72. - Avoid installing @lawkit/ui@0.1.72. 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.
