A package installation changes broad AI-agent control surfaces and enables package hook execution in later agent sessions. - **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:** 0.12.0 - **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 can automatically modify existing Claude and DSH agent homes. It installs agent payloads and registers a lifecycle bridge without an explicit setup command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-13T15:04:41.401Z - **Finished:** 2026-09-13T15:05:39.372Z - **Download time:** 774 ms - **Static scan time:** 181 ms - **AI review time:** 57015 ms - **Total time:** 57971 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 can automatically modify existing Claude and DSH agent homes. It installs agent payloads and registers a lifecycle bridge without an explicit setup command. - **Trigger:** npm install runs postinstall when ~/.claude or ~/.dsh already exists and CI is unset. - **Impact:** A package installation changes broad AI-agent control surfaces and enables package hook execution in later agent sessions. - **Evidence paths:** package.json, bin/dcs.js, dcs/bridge/index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-13T15:05:39.372Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic agent-home payload installation and DSH lifecycle registration. - **Attack narrative:** The postinstall hook selects existing Claude or DSH homes and installs its payload automatically. For DSH it writes a bridge registration and appends AGENTS.md, causing later agent lifecycle events to invoke installed Python hooks. This is unconsented install-time mutation of foreign, broad AI-agent control surfaces. - **Rationale:** This is a concrete automatic postinstall control-surface mutation, which meets the blocking policy. No network exfiltration was needed to establish the install-hook abuse. - **Files touched:** ~/.claude/dcs, ~/.claude/agents/dcs-\*.md, ~/.claude/skills/dcs-\*, ~/.dsh/dcs, ~/.dsh/agents/dcs-\*.md, ~/.dsh/skills/dcs-\*, ~/.dsh/AGENTS.md, ~/.dsh/profiles/web/cordis.patch.yml, ~/.dsh/dcs-install.json ### 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 invokes the installer., The installer targets existing ~/.claude and ~/.dsh agent homes without an explicit user command., It copies payloads and appends a DSH bridge mount and AGENTS.md block., The installed bridge can spawn Python hook scripts during agent lifecycle events. - **Evidence against:** No network endpoint, credential harvesting, or exfiltration code was found., package.json has no runtime self-dependency. ## Affected versions and remediation This report applies to dcs-command-system@0.12.0. - Avoid installing dcs-command-system@0.12.0. 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.
