Existing Claude or Codex installations can receive or have this package's agent skills replaced without an explicit user 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:** 1.8.23 - **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. Installation automatically invokes an initializer that writes package-supplied skills into AI-agent control directories. This is an unconsented lifecycle mutation of foreign agent surfaces. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 97.0% - **Started:** 2026-09-23T22:16:12.805Z - **Finished:** 2026-09-23T22:17:31.633Z - **Download time:** 503 ms - **Static scan time:** 257 ms - **AI review time:** 78067 ms - **Total time:** 78828 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Installation automatically invokes an initializer that writes package-supplied skills into AI-agent control directories. This is an unconsented lifecycle mutation of foreign agent surfaces. - **Trigger:** npm postinstall runs after package installation. - **Impact:** Existing Claude or Codex installations can receive or have this package's agent skills replaced without an explicit user command. - **Evidence paths:** package.json, scripts/postinstall.cjs, dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-23T22:17:31.633Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook runs the CLI with /init; the bundled initializer selects agent skill roots, removes prior package directories, creates them, and copies SKILL.md files. - **Attack narrative:** Installing the package triggers its postinstall script, which silently invokes /init. The bundled CLI identifies Claude and Codex skill locations and removes then recreates package skill directories before copying supplied skill files. This mutates external AI-agent control surfaces during dependency installation without an explicit setup action. - **Rationale:** The automatic lifecycle chain performs concrete writes to foreign AI-agent skill directories. The bundled implementation is also obfuscated, reducing auditability of this install-time behavior. - **Files touched:** .claude/skills/sino-bc-cli/SKILL.md, .codex/skills/sino-bc-cli/SKILL.md ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package declares an automatic postinstall lifecycle hook., The postinstall hook starts the CLI with /init without user interaction., The bundled CLI targets Claude and Codex skill directories., The initializer removes an existing target directory and copies its skill file into it. ## Affected versions and remediation This report applies to sino-bc-cli@1.8.23. - Avoid installing sino-bc-cli@1.8.23. 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.
