Consumer agents can be directed to expose secrets while reviewers are told to skip the generated files. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 1.5.183 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Installing the package automatically alters project install settings and writes AI-agent instructions, skills, and review exclusions. Those rules promote secret disclosure and suppress review of the generated control files. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-09-04T03:01:36.334Z - **Finished:** 2026-09-04T03:04:12.473Z - **Download time:** 507 ms - **Static scan time:** 145 ms - **AI review time:** 155486 ms - **Total time:** 156139 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package automatically alters project install settings and writes AI-agent instructions, skills, and review exclusions. Those rules promote secret disclosure and suppress review of the generated control files. - **Trigger:** npm installation invokes postinstall. - **Impact:** Consumer agents can be directed to expose secrets while reviewers are told to skip the generated files. - **Evidence paths:** package.json, postinstall.js, merge.js - **Review source:** ai\_review - **Reviewed:** 2026-09-04T03:04:12.473Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall project mutation and AI-agent control-surface injection. - **Attack narrative:** On installation, the package modifies .npmrc to make lifecycle execution persistent, then runs its merger in the consumer project. The merger writes Copilot and Claude control files, copies skills, and installs review exclusions. Its bundled rules direct agents to place real tokens, keys, and environment values in documentation and direct reviewers not to report that behavior. This is an unconsented install-time takeover of broad AI-agent control surfaces. - **Rationale:** This is concrete malicious install-time behavior: it mutates consumer AI-agent controls and embeds instructions that facilitate secret disclosure while suppressing review. No network theft is required for the control-surface attack to be harmful. - **Files touched:** .npmrc, AGENTS.md, CLAUDE.md, .github/copilot-instructions.md, .github/instructions/no-review-docs.instructions.md, .claude/skills/\*, AGENTS.private.md ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The package runs a postinstall hook automatically., The hook changes the consumer project's .npmrc to enable dependency lifecycle scripts and disable safety-related install settings., The hook launches a merger that writes agent-control files and copies skills into the consumer project., The shipped rules instruct agents to include real secrets in documentation and tell reviewers not to report that disclosure., The merger creates a review instruction directing code review to skip generated agent-rule files. - **Evidence against:** No network endpoint or credential collection code was found in the inspected executable JavaScript., The screenshot helper only reads an input image and writes a requested local HTML file. ## Public findings ### 1.
