Future agent events execute the package-owned binary through configured shell hooks. - **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:** 0.8.0 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Install-time setup mutates detected foreign AI-agent hook/plugin configurations to run kbglow commands. No exfiltration endpoint was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 95.0% - **Started:** 2026-08-14T13:10:56.685Z - **Finished:** 2026-08-14T13:12:41.597Z - **Download time:** 519 ms - **Static scan time:** 118 ms - **AI review time:** 104274 ms - **Total time:** 104912 ms ## Security analysis ### Published attack-surface review - **Summary:** Install-time setup mutates detected foreign AI-agent hook/plugin configurations to run kbglow commands. No exfiltration endpoint was found. - **Trigger:** npm postinstall when supported agent configuration directories exist - **Impact:** Future agent events execute the package-owned binary through configured shell hooks. - **Evidence paths:** package.json, scripts/setup.js, bin/kbglow - **Review source:** ai\_review - **Reviewed:** 2026-08-14T13:12:41.597Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic cross-vendor AI-agent hook and plugin injection - **Attack narrative:** Installing the package runs setup without an explicit setup command. The setup detects several unrelated AI CLI configuration directories and writes or refreshes hooks/plugins that execute the bundled binary during agent events. This is an unconsented postinstall mutation of foreign, cross-vendor AI-agent control surfaces. - **Rationale:** The observable purpose is a keyboard notification utility, but its npm postinstall automatically injects executable hooks across third-party AI-agent configurations. That meets the firewall block boundary despite no observed network or credential theft. Product guard normalized a concrete AI-agent control hijack publish\_block to the blockable dangerous-capability shape. - **Files touched:** package.json, scripts/setup.js, bin/kbglow, ~/.claude/settings.json, ~/.gemini/settings.json, ~/.qwen/settings.json, ~/.config/opencode/plugins/kbglow.js ### Review decision - **Verdict:** Malicious - **Confidence:** 95.0% - **Recommended action:** publish\_block - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** npm postinstall invokes setup automatically., Setup writes executable hooks into detected third-party AI CLI configurations., It generates an opencode plugin that executes shell commands on agent events. - **Evidence against:** No network endpoint or credential-harvesting code found., The injected commands only invoke the bundled backlight binary., LaunchAgent persistence requires explicit --watch. ## Public findings ### 1.
