Existing Claude Code and Codex configurations can be modified during package install by an opaque binary the user did not invoke. - **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:** 0.6.10 - **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. On npm install, postinstall downloads the Aegis release binary and, if a Claude Code or Codex home directory already exists, runs it with install-hooks --all. That writes into foreign agent control surfaces without an install-time consent prompt. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-09-26T07:34:15.328Z - **Finished:** 2026-09-26T07:35:07.583Z - **Download time:** 764 ms - **Static scan time:** 30 ms - **AI review time:** 51461 ms - **Total time:** 52255 ms The recorded confidence comes from the underlying analysis.

That writes into foreign agent control surfaces without an install-time consent prompt. - **Trigger:** npm install lifecycle postinstall, when the user home already contains .claude or .codex and AEGIS\_NPM\_SKIP\_HOOKS is not 1. - **Impact:** Existing Claude Code and Codex configurations can be modified during package install by an opaque binary the user did not invoke. - **Evidence paths:** package.json, scripts/install.js - **Review source:** ai\_review - **Reviewed:** 2026-09-26T07:35:07.583Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** scripts/install.js downloads the platform binary, verifies its checksum, chmod 0755, then spawnSync(binary, \["install-hooks", "--all"\]). - **Attack narrative:** Installing @iliasalmerekov/aegis@0.6.10 runs scripts/install.js from postinstall. The script downloads a GitHub release binary into vendor/aegis, checks SHA256, and makes it executable. If ~/.claude or ~/.codex exists, it immediately executes that binary with install-hooks --all. Skipping requires a pre-set environment variable. The hook payload itself is not in the JavaScript, so install mutates foreign agent configs through an opaque binary without a consent prompt. - **Rationale:** Postinstall unconditionally launches a downloaded binary that installs hooks into existing Claude Code and Codex directories, which is an unconsented mutation of foreign agent control surfaces. An environment opt-out and a checksum do not supply user consent for that install-time write. - **Files touched:** vendor/aegis, ~/.claude, ~/.codex - **Network endpoints:** https://github.com/IliasAlmerekov/aegis-shellguard/releases/download/v0.6.10 ### Review decision - **Verdict:** Malicious - **Confidence:** 88.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** npm postinstall runs node scripts/install.js with no user prompt., When ~/.claude or ~/.codex already exists, postinstall runs the downloaded vendor binary as install-hooks --all. The only gate is the opt-out env AEGIS\_NPM\_SKIP\_HOOKS=1., That binary is fetched from the package GitHub release URL (or AEGIS\_NPM\_BASE\_URL), marked executable, and invoked during the same install. - **Evidence against:** Hook setup is skipped when neither agent directory exists, and the script does not create those directories., Shell-proxy setup is only printed; startup files are not edited in this script., The downloaded file is checked against checksums.json SHA256 values before it is kept. ## Affected versions and remediation This report applies to @iliasalmerekov/aegis@0.6.10. - Avoid installing @iliasalmerekov/aegis@0.6.10. 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.
