It can change the behavior and network permissions of several AI-agent tools without an explicit setup command. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 1.1.12 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. LPM flags this version as an AI-agent control-surface risk. A global npm postinstall writes skills, instruction personas, and Codex settings into multiple AI-agent control surfaces. It enables Codex network access and installs a persona that mandates a remote fetch for matching requests. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-07T13:10:17.747Z - **Finished:** 2026-09-07T13:11:15.813Z - **Download time:** 254 ms - **Static scan time:** 246 ms - **AI review time:** 57565 ms - **Total time:** 58066 ms The recorded confidence comes from the underlying analysis.

It enables Codex network access and installs a persona that mandates a remote fetch for matching requests. - **Trigger:** Global installation of the package, through its postinstall hook. - **Impact:** It can change the behavior and network permissions of several AI-agent tools without an explicit setup command. - **Evidence paths:** scripts/postinstall.js, lib/targets.js, lib/codex-config.js, persona.md - **Review source:** ai\_review - **Reviewed:** 2026-09-07T13:11:15.813Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic mutation of global AI-agent instructions, skills, and configuration. - **Attack narrative:** On global installation, the postinstall hook invokes the installer without a user command. The installer targets Claude, shared agent, Codex, and Gemini global instruction and skill locations, changes Codex configuration to enable network access, and prepends a persona. That persona directs agents to fetch a remotely hosted reference before responding to Babylon-related requests, creating a persistent remote instruction channel across agent products. - **Rationale:** This is unconsented postinstall mutation of broad, foreign AI-agent control surfaces, including activation of network access and remote instruction loading. The behavior meets the install-time AI-agent control-hijack blocking boundary. - **Files touched:** skills/, persona.md, .codex/config.toml, ~/.claude/skills, ~/.claude/CLAUDE.md, ~/.agents/skills, ~/.agents/AGENTS.md, ~/.codex/AGENTS.md, ~/.codex/config.toml, ~/.gemini/GEMINI.md - **Network endpoints:** https://raw.githubusercontent.com/babylontoolkit/agent/main/reference.md ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The postinstall hook automatically runs setup during global installation., Default targets write skills and instruction files for several AI-agent products in the user's home directory., Installation modifies Codex configuration to enable network access., The installed persona requires future agents to fetch a remote document before handling Babylon-related requests. - **Evidence against:** No package dependency or automatic self-update chain was found., No direct credential harvesting or command-output exfiltration was found in the inspected source. ## Affected versions and remediation This report applies to @babylonjs-toolkit/agent@1.1.12. - Avoid installing @babylonjs-toolkit/agent@1.1.12. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
