Adds or overwrites instructions consumed by foreign AI assistants and removes the safe-delete preload from installer child processes. - **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:** 0.1.30 - **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. Global npm installation automatically changes foreign AI-agent skill directories without an explicit setup command. The installation helper also removes a safe-delete preload. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-10-01T20:35:18.147Z - **Finished:** 2026-10-01T20:36:22.740Z - **Download time:** 2535 ms - **Static scan time:** 176 ms - **AI review time:** 61880 ms - **Total time:** 64593 ms The recorded confidence comes from the underlying analysis.

The installation helper also removes a safe-delete preload. - **Trigger:** Global npm installation outside CI when GUAN\_SKIP\_INSTALL\_SKILL is not 1. - **Impact:** Adds or overwrites instructions consumed by foreign AI assistants and removes the safe-delete preload from installer child processes. - **Evidence paths:** package.json, bin/postinstall.js, bin/run.js, bin/install-env.js - **Review source:** ai\_review - **Reviewed:** 2026-10-01T20:36:22.740Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall invokes install-skill, runs a globally scoped skills installer with automatic confirmation, and copies the skill into CodeBuddy and WorkBuddy configuration directories. - **Attack narrative:** The npm postinstall hook invokes install-skill during ordinary global installation. That command automatically runs a global skills installer and copies the package's skill into CodeBuddy and WorkBuddy agent directories. These changes require no separate user setup action. The helper additionally strips WorkBuddy's safe-delete preload from the child environment. The global-only gate and skip variable limit activation but do not establish consent to modifying foreign agent controls. - **Rationale:** Source establishes automatic postinstall mutation of foreign AI-agent control surfaces, which meets the blocking policy. Package-related skill content and installation guards do not neutralize that behavior. - **Files touched:** .codebuddy, .workbuddy ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The npm postinstall hook activates an automatic skill installer., Global installs outside CI invoke install-skill unless an environment variable disables it., The installer runs skills add with automatic confirmation and global installation flags., The installer copies the package skill into foreign CodeBuddy and WorkBuddy agent configuration directories., The installation environment removes WorkBuddy's safe-delete preload. - **Evidence against:** Local installs, CI environments, and the explicit skip variable bypass automatic installation., The installed skill concerns the package's ETL functionality; no credential theft was established. ## Affected versions and remediation This report applies to @guandata/guanetl@0.1.30. - Avoid installing @guandata/guanetl@0.1.30. 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.
