The package can alter the instructions and capabilities loaded by installed Cursor or Codex agent environments. - **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:** 1.8.19 - **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. Installing the package automatically starts its CLI and initializes packaged skills in external AI-agent control directories. This is an unconsented postinstall modification of foreign agent surfaces. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-09-23T22:16:12.755Z - **Finished:** 2026-09-23T22:17:23.277Z - **Download time:** 510 ms - **Static scan time:** 291 ms - **AI review time:** 69720 ms - **Total time:** 70522 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:** Installing the package automatically starts its CLI and initializes packaged skills in external AI-agent control directories. This is an unconsented postinstall modification of foreign agent surfaces. - **Trigger:** npm runs postinstall during package installation. - **Impact:** The package can alter the instructions and capabilities loaded by installed Cursor or Codex agent environments. - **Evidence paths:** package.json, scripts/postinstall.cjs, dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-23T22:17:23.277Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The lifecycle script invokes /init; the obfuscated bundle selects agent directories, removes an existing package skill directory, and copies in bundled skills. - **Attack narrative:** An npm installation runs scripts/postinstall.cjs, which silently invokes the package CLI with /init. The bundled, obfuscated CLI identifies external Cursor and Codex skill locations and replaces a skill subdirectory with package-provided content. This establishes an automatic path from dependency installation to modification of AI-agent control surfaces without an explicit user command. - **Rationale:** The automatic lifecycle hook performs broad, unconsented mutation of foreign AI-agent directories. This meets the install-control-surface policy for blocking publication. - **Files touched:** .cursor, .codex ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **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 launches the bundled CLI with /init without user interaction., The bundled CLI targets Cursor and Codex agent directories., Its initialization removes an existing skill directory and copies packaged skill content into it. - **Evidence against:** No network endpoint or credential-exfiltration sink was confirmed in the inspected lifecycle path. ## Affected versions and remediation This report applies to sino-bc-cli@1.8.19. - Avoid installing sino-bc-cli@1.8.19. 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.
