Unconsented persistence and command execution through a foreign AI-agent control surface. - **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:** 0.2.0 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Install-time code mutates the user's Claude Code control configuration. It registers package commands as hooks that execute on agent events. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-08-06T13:20:13.547Z - **Finished:** 2026-08-06T13:20:44.789Z - **Download time:** 255 ms - **Static scan time:** 16 ms - **AI review time:** 30971 ms - **Total time:** 31242 ms ## Security analysis ### Published attack-surface review - **Summary:** Install-time code mutates the user's Claude Code control configuration. It registers package commands as hooks that execute on agent events. - **Trigger:** npm postinstall - **Impact:** Unconsented persistence and command execution through a foreign AI-agent control surface. - **Evidence paths:** package.json, scripts/setup.js, bin/kbglow, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-06T13:20:44.789Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** writes Claude Code command hooks into user settings - **Attack narrative:** On installation, package.json invokes scripts/setup.js with --postinstall. That script reads and backs up ~/.claude/settings.json, then writes hooks invoking its bundled binary for Notification, PostToolUse, UserPromptSubmit, and Stop. These hooks execute later through Claude Code without a separate user setup command. - **Rationale:** The package performs an unconsented postinstall mutation of the user's Claude Code settings, a foreign AI-agent control surface. Its stated keyboard-notification purpose and lack of network behavior do not remove that install-time control-surface write. - **Files touched:** scripts/setup.js, bin/kbglow, ~/.claude/settings.json, ~/.claude/settings.json.kbglow-bak, /tmp/kbglow.pid ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs setup.js in postinstall., scripts/setup.js writes ~/.claude/settings.json during install., Setup inserts command hooks for four Claude Code events., It backs up then modifies existing user agent settings. - **Evidence against:** README.md openly documents the automatic hook setup., No network endpoint or credential collection was found., Binary strings indicate local keyboard-backlight control. ## Public findings ### 1. High: Install Time Lifecycle Scripts - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Package defines install-time lifecycle scripts. Public source snippet (untrusted): ```json scripts.postinstall = node scripts/setup.js --postinstall ``` ### 2. Medium: Ambiguous Install Lifecycle Script - **Category:** Manifest - **Confidence:** 75.0% - **Path:** package.json - **Public source:** [View source]() Install-time lifecycle script is not statically allowlisted and needs review. Public source snippet (untrusted): ```json scripts.postinstall = node scripts/setup.js --postinstall ``` ### 3. Low: Non Install Lifecycle Scripts - **Category:** Manifest - **Confidence:** 80.0% Package declares lifecycle scripts that are not normally run for registry tarball installs. ### 4. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 5. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 6. Critical: Ai Agent Control Hijack - **Category:** Source - **Confidence:** 90.0% - **Path:** scripts/setup.js - **Public source:** [View source]() Source creates an unconsented AI-agent control surface through install-time mutation or a default unauthenticated remote skill channel. Public source snippet (untrusted): ```javascript L1: #!/usr/bin/env node L2: // Wire kbglow into Claude Code's hooks (~/.claude/settings.json) so the L3: // keyboard blinks while Claude is waiting for approval. ... L18: L19: const settingsDir = path.join(os.homedir(), '.claude'); L20: const settingsPath = path.join(settingsDir, 'settings.json'); ... L53: } L54: fs.writeFileSync(settingsPath + '.kbglow-bak', raw); L55: backedUp = true; ... L67: L68: fs.mkdirSync(settingsDir, { recursive: true }); L69: fs.writeFileSync(settingsPath, JSON.stringify(settings, null, 2) + '\n'); ``` ### 7. High: External Ai Agent Control Surface Mutation - **Category:** Source - **Confidence:** 94.0% - **Path:** scripts/setup.js - **Public source:** [View source]() Runtime or CLI source writes behavior-bearing configuration into a user or project AI-agent control surface. Public source snippet (untrusted): ```javascript Runtime or CLI code links a write operation to an explicit external AI-agent control path: #!/usr/bin/env node 'use strict'; const fs = require('fs'); const path = require('path'); const os = require('os'); const postinstall = process.argv.includes('--postinstall'); const remove = process.argv.includes('--remove'); const settingsdir = path.join(os.homedir(), '.claude'); const settingspath = path.join(settings ``` ### 8. Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 80.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** postinstall, prepare - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** kbglow - **Ecosystem:** npm - **Version:** 0.2.0 - **License:** MIT - **Version published:** 2026-08-06T12:37:59.096Z - **Package first seen:** 2026-08-06T13:20:44.789Z - **Package last seen:** 2026-08-14T13:12:41.597Z - **Known versions:** 6 - **Latest version:** 0.8.0 - **Appeal under review:** No - **Description:** Your Mac's keyboard backlight blinks while your AI agent (e.g. Claude Code) is waiting for approval - **Author:** totota-08 - **Keywords:** claude-code, claude, ai-agent, keyboard-backlight, notification, macos - **Supported OS:** darwin - **Artifact files:** 6 - **Artifact unpacked size:** 189,213 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
