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. npm installation downloads and executes an external native binary.

That binary is automatically told to install IDE and AI-agent hooks. - **Trigger:** npm postinstall - **Impact:** Can alter AI-agent or editor integrations without a separate user command; the downloaded binary is outside this source review. - **Evidence paths:** package.json, install.js - **Review source:** ai\_review - **Reviewed:** 2026-09-08T12:50:47.975Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Downloads, executes, and delegates hook installation to an opaque binary. - **Attack narrative:** Installing the package runs a postinstall hook. It downloads a native executable into ~/.autter/bin, executes it, and invokes install-hooks to configure IDE and agent integrations; source states the daemon rechecks those hooks daily. Because hook behavior resides in the downloaded binary and is activated without an explicit setup command, this is unconsented install-time AI-agent control-surface mutation. - **Rationale:** The package creates a concrete automatic chain from npm postinstall to an externally fetched executable that installs agent/editor hooks. This meets the install-control-surface blocking policy despite checksum verification and telemetry disclosure. - **Files touched:** package.json, install.js, ~/.autter/bin/autter - **Network endpoints:** https://github.com/autter-dev/autter-cli/releases/download/, https://us.i.posthog.com/capture/ ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package automatically runs install.js after npm installation., The hook downloads a platform binary from GitHub and writes it as an executable under the user home directory., The downloaded opaque binary is immediately executed with install-hooks, which sets up IDE and agent hooks and is described as being rechecked daily., Installation sends an opt-out telemetry event containing operating system, architecture, and release version to PostHog. - **Evidence against:** The download URL is pinned to the package release version by default., The script attempts SHA-256 verification against a release checksum file., The telemetry payload is limited in source to platform, architecture, version, and an install trigger, with an environment-variable opt-out. ## Affected versions and remediation This report applies to @autter/cli@1.7.2. - Avoid installing @autter/cli@1.7.2. 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.
