Installing the package can automatically add or replace AI-agent skill content under .agents/skills/sino-bc-cli. - **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:** 1.8.15 - **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 modifies an AI-agent skills directory in the user's home area. No network attack was identified, but the lifecycle hook mutates a foreign agent control surface without an explicit user command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-09-23T22:16:12.788Z - **Finished:** 2026-09-23T22:17:26.589Z - **Download time:** 515 ms - **Static scan time:** 261 ms - **AI review time:** 73024 ms - **Total time:** 73801 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 modifies an AI-agent skills directory in the user's home area. No network attack was identified, but the lifecycle hook mutates a foreign agent control surface without an explicit user command. - **Trigger:** npm runs the package postinstall lifecycle hook. - **Impact:** Installing the package can automatically add or replace AI-agent skill content under .agents/skills/sino-bc-cli. - **Evidence paths:** package.json, scripts/postinstall.cjs, dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-23T22:17:26.589Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook launches dist/index.js with /init; the bundled code configures an always-written .agents skills target, removes the package skill directory, and copies bundled skill content into it. - **Attack narrative:** A registry install triggers postinstall, which launches the CLI initializer without requiring a separate user setup command. The initializer writes into the home AI-agent skills hierarchy and force-replaces its package-owned skill directory. This is unconsented install-time mutation of a foreign AI-agent control surface. - **Rationale:** The automatic postinstall chain reaches code that writes to the .agents AI-agent control surface. This is concrete install-hook abuse under the stated policy, despite the write being scoped to the package skill directory. - **Files touched:** .agents/skills/sino-bc-cli ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package defines an automatic postinstall lifecycle hook., The postinstall script starts the CLI with /init during installation., The bundled initializer targets the home .agents skills control surface with always-write enabled., The initializer force-removes its existing skill directory and copies package-provided content into it. - **Evidence against:** The observed writes are scoped to a sino-bc-cli skill subdirectory, rather than arbitrary files. ## Affected versions and remediation This report applies to sino-bc-cli@1.8.15. - Avoid installing sino-bc-cli@1.8.15. 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.
