Unconsented persistence and control over Claude Code tool permissions across projects. - **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:** 0.1.4 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Installation mutates the user-wide Claude Code hook and settings control surface. It installs numerous enforcement hooks and a downloaded executable that affect later agent sessions. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-08-06T15:34:44.218Z - **Finished:** 2026-08-06T15:35:24.116Z - **Download time:** 1266 ms - **Static scan time:** 1466 ms - **AI review time:** 37164 ms - **Total time:** 39898 ms ## Security analysis ### Published attack-surface review - **Summary:** Installation mutates the user-wide Claude Code hook and settings control surface. It installs numerous enforcement hooks and a downloaded executable that affect later agent sessions. - **Trigger:** npm postinstall - **Impact:** Unconsented persistence and control over Claude Code tool permissions across projects. - **Evidence paths:** package.json, scripts/postinstall.js, hooks/harness-self-protection-guard.sh, hooks/achilles-protocol-activation-watcher.sh - **Review source:** ai\_review - **Reviewed:** 2026-08-06T15:35:24.116Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** global Claude hook installation, settings registration, and binary download - **Attack narrative:** On npm install, the package copies its skills and a large hook suite into the user-wide Claude Code directory and writes registrations into ~/.claude/settings.json. Those hooks observe prompts and agent calls and can deny Bash or Write/Edit operations. The same lifecycle script downloads an executable jq release asset to that global hook surface and runs it for version checking without cryptographic integrity verification. - **Rationale:** This is concrete, unconsented postinstall mutation of a foreign, broad AI-agent control surface, not merely an explicit CLI setup flow. The lifecycle persistence meets the block policy despite the absence of credential exfiltration. - **Files touched:** scripts/postinstall.js, hooks/, skills/, ~/.claude/hooks/, ~/.claude/hooks/bin/jq, ~/.claude/settings.json, \/.claude/skills/ - **Network endpoints:** https://github.com/jqlang/jq/releases/download/jq-1.7.1/ ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs scripts/postinstall.js automatically., scripts/postinstall.js copies skills and hooks into ~/.claude., scripts/postinstall.js registers broad PreToolUse/UserPromptSubmit hooks in ~/.claude/settings.json., Postinstall downloads and executes jq at ~/.claude/hooks/bin/jq without a cryptographic hash., Installed hooks can deny agent Write/Edit and Bash operations. - **Evidence against:** No credential harvesting or unrelated data exfiltration found., Network download is a named jq GitHub release asset. ## Public findings ### 1.
