An opaque executable can modify existing AI-agent configuration without an explicit user command. - **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:** 0.6.5 - **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 downloads an opaque native executable and runs it automatically. If existing Claude or Codex configuration directories are found, it runs the executable with install-hooks --all against those foreign agent control surfaces. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 97.0% - **Started:** 2026-09-17T01:26:23.012Z - **Finished:** 2026-09-17T01:27:06.983Z - **Download time:** 1040 ms - **Static scan time:** 29 ms - **AI review time:** 42901 ms - **Total time:** 43971 ms The recorded confidence comes from the underlying analysis.

If existing Claude or Codex configuration directories are found, it runs the executable with install-hooks --all against those foreign agent control surfaces. - **Trigger:** npm postinstall during package installation on a supported platform with $HOME/.claude or $HOME/.codex present - **Impact:** An opaque executable can modify existing AI-agent configuration without an explicit user command. - **Evidence paths:** package.json, scripts/install.js, bin/aegis.js - **Review source:** ai\_review - **Reviewed:** 2026-09-17T01:27:06.983Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote native payload download followed by automatic agent-hook installation - **Attack narrative:** The postinstall script downloads a platform-specific native binary, checksum-verifies it, installs it as vendor/aegis, and executes it. When either existing agent directory is present, this happens with install-hooks --all. The package does not include the native payload, so the hook behavior cannot be audited from the published source; this is an unconsented install-time mutation path for existing AI-agent control surfaces. - **Rationale:** The automatic postinstall chain fetches and executes an opaque native payload, then targets pre-existing Claude or Codex configuration through install-hooks --all. This is a concrete unconsented install-time AI-agent control-surface risk. - **Files touched:** vendor/aegis.tmp, vendor/aegis, $HOME/.claude, $HOME/.codex - **Network endpoints:** github.com, release-assets.githubusercontent.com ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** A postinstall lifecycle hook runs the installer automatically., The installer downloads a native executable, writes it under vendor, and executes it., On systems with existing Claude or Codex directories, installation automatically invokes install-hooks --all., The downloaded executable is opaque in this package, so its agent-config mutations cannot be source-audited. - **Evidence against:** The installer verifies the downloaded file against a bundled SHA-256 value., No credential harvesting or data exfiltration is present in the JavaScript source. ## Affected versions and remediation This report applies to @iliasalmerekov/aegis@0.6.5. - Avoid installing @iliasalmerekov/aegis@0.6.5. 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.
