It silently expands the package's control over AI-agent sessions, trusts the current workspace, and may disclose session metadata and prompts to a remote service. - **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:** 6.0.1 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. A global npm postinstall installs persistent hooks into Claude settings, changes workspace trust, and configures MCP servers for multiple AI clients. Those hooks run during later agent sessions and can submit a session digest to a remote model service when an ambient key is available. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-28T04:58:11.614Z - **Finished:** 2026-08-28T04:59:52.690Z - **Download time:** 1007 ms - **Static scan time:** 10370 ms - **AI review time:** 89694 ms - **Total time:** 101076 ms ## Security analysis ### Published attack-surface review - **Summary:** A global npm postinstall installs persistent hooks into Claude settings, changes workspace trust, and configures MCP servers for multiple AI clients. Those hooks run during later agent sessions and can submit a session digest to a remote model service when an ambient key is available. - **Trigger:** Installing the package globally through npm outside CI. - **Impact:** It silently expands the package's control over AI-agent sessions, trusts the current workspace, and may disclose session metadata and prompts to a remote service. - **Evidence paths:** package.json, scripts/postinstall.cjs, install-hooks.sh, hooks-core/wire.mjs, plugin/hooks/lib/harvest.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-28T04:59:52.690Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Lifecycle-driven AI client configuration, hook persistence, and conditional session-digest transmission. - **Attack narrative:** On a global npm installation, postinstall launches the bundled installer without a consent prompt. The installer copies hooks, wires them into Claude session and tool events, marks the current workspace trusted, and registers the package as an MCP server in other AI client configurations. The installed hook code enables a remote Anthropic request whenever an ambient API key exists, sending a structured session digest. This is unconsented lifecycle mutation of broad, foreign AI-agent control surfaces. - **Rationale:** The package performs unconsented postinstall mutation of multiple AI-agent configurations and workspace trust state. This meets the firewall block boundary regardless of the scanner similarity hint. - **Files touched:** scripts/postinstall.cjs, install-hooks.sh, scripts/wire-hooks.mjs, plugin/hooks/lib/harvest.mjs, ~/.claude-global/hooks/token-optimizer, ~/.claude/settings.json, ~/.claude.json, ~/.cursor/mcp.json, .vscode/mcp.json - **Network endpoints:** https://api.anthropic.com/v1/messages ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** A postinstall hook automatically runs an installer during global installation without asking for confirmation., The installer copies persistent hooks and registers them for agent session, tool-use, and compaction events., The installer changes agent trust state and writes MCP entries for several unrelated AI clients., Installed hooks can send a session digest to Anthropic whenever an ambient API key is present. - **Evidence against:** The lifecycle hook skips ordinary dependency installs and CI., The hook-wiring helper preserves non-package hook entries, but this does not make the automatic foreign configuration changes consensual. ## Public findings ### 1.
