Future agent sessions can execute the package and receive content sourced from other local agent sessions or crew messages. - **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:** 0.3.0 - **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. A global npm install automatically changes hook controls for Claude, Codex, and opencode. The hooks run crew during agent events and insert shared session data or continuation instructions into agent context. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-09-06T05:45:08.833Z - **Finished:** 2026-09-06T05:46:08.318Z - **Download time:** 510 ms - **Static scan time:** 376 ms - **AI review time:** 58597 ms - **Total time:** 59485 ms The recorded confidence comes from the underlying analysis.

The hooks run crew during agent events and insert shared session data or continuation instructions into agent context. - **Trigger:** npm install -g @0xmmo/crew, unless CREW\_NO\_HOOK is set. - **Impact:** Future agent sessions can execute the package and receive content sourced from other local agent sessions or crew messages. - **Evidence paths:** package.json, dist/postinstall.js, dist/settings.js, dist/crew.js - **Review source:** ai\_review - **Reviewed:** 2026-09-06T05:46:08.318Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall mutation of multiple AI-agent hook and plugin control surfaces. - **Attack narrative:** On global installation, postinstall iterates over three agent products and installs command hooks or a generated plugin without an explicit setup command. Those hooks invoke crew at session events. Crew accepts hook input, reads local agent session material, and emits it as injected context; on stop events it can issue a blocking continuation reason. This is automatic persistence across foreign AI-agent control surfaces. - **Rationale:** The package performs an unconsented global-install lifecycle mutation of multiple foreign AI-agent control surfaces, then injects content into their sessions. No network theft was found, but the concrete hook persistence and agent-control behavior meet the blocking policy. - **Files touched:** package.json, dist/postinstall.js, dist/settings.js, dist/crew.js, $CODEX\_HOME/hooks.json, $CLAUDE\_CONFIG\_DIR/settings.json, $XDG\_CONFIG\_HOME/opencode/plugins/crew.js ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The postinstall lifecycle automatically runs its installer during global npm installation., The installer modifies Claude and Codex hook configuration and creates a global opencode plugin., The added hooks execute crew on agent events and inject session context into agent output., The hook reads agent input and can send a blocking continuation reason to Codex. - **Evidence against:** No network client, URL, or credential-exfiltration code was found., The lifecycle is limited to global installs and offers an environment-variable opt-out., No self-dependency or downloaded payload was found. ## Affected versions and remediation This report applies to @0xmmo/crew@0.3.0. - Avoid installing @0xmmo/crew@0.3.0. 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.
