Package-controlled instructions and helper files become available to the consumer's Claude Code environment. - **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:** 2.2.0 - **Selected version is latest:** Yes - **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 writes its bundled Claude skills into the consuming project's AI-agent configuration. Existing skill files may be replaced. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-13T11:38:01.365Z - **Finished:** 2026-09-13T11:38:48.994Z - **Download time:** 1041 ms - **Static scan time:** 228 ms - **AI review time:** 46360 ms - **Total time:** 47629 ms The recorded confidence comes from the underlying analysis.

Existing skill files may be replaced. - **Trigger:** npm installation runs postinstall. - **Impact:** Package-controlled instructions and helper files become available to the consumer's Claude Code environment. - **Evidence paths:** package.json, scripts/copy-skills.cjs - **Review source:** ai\_review - **Reviewed:** 2026-09-13T11:38:48.994Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Recursive overwrite of project .claude/skills from the package. - **Attack narrative:** The package declares a postinstall hook that runs automatically during npm installation. That script uses npm's INIT\_CWD to locate the consumer project, then recursively copies the package's .claude/skills tree into the consumer's .claude/skills directory. It overwrites existing files, changing a foreign AI-agent control surface without an explicit setup command. No lifecycle network or shell execution was found, but the automatic broad agent-configuration mutation is concrete install-hook abuse. - **Rationale:** The automatic postinstall mutation of the consumer project's Claude skill directory meets the install-control-surface block policy. The absence of network activity does not neutralize the unconsented overwrite behavior. - **Files touched:** .claude/skills/\*\* ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The npm postinstall hook automatically runs the skill-copying script., The script derives the consuming project's root from INIT\_CWD and targets its .claude/skills directory., The recursive copy overwrites existing consumer skill files, mutating a broad AI-agent control surface without a user command. - **Evidence against:** The postinstall script contains no network, shell, or credential-exfiltration behavior., The separately shipped Firebase shell helpers are not invoked by the lifecycle hook. ## Affected versions and remediation This report applies to @xbg.solutions/bpsk-core@2.2.0. - Avoid installing @xbg.solutions/bpsk-core@2.2.0. 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.
