Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. LPM treats this as warn-only first-party agent extension lifecycle risk. At npm postinstall, the package fetches a platform binary into ~/.autter/bin and executes it with install-hooks. The downloaded binary is outside the inspected source and may alter IDE/agent integration state. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-08-16T18:20:18.967Z - **Finished:** 2026-08-16T18:20:57.530Z - **Download time:** 506 ms - **Static scan time:** 67 ms - **AI review time:** 37989 ms - **Total time:** 38563 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:** At npm postinstall, the package fetches a platform binary into ~/.autter/bin and executes it with install-hooks. The downloaded binary is outside the inspected source and may alter IDE/agent integration state. - **Trigger:** npm installation with lifecycle scripts enabled - **Impact:** Unconsented first-party agent/editor extension setup and ongoing daemon-managed hook lifecycle. - **Evidence paths:** package.json, install.js, bin/autter.js - **Review source:** ai\_review - **Reviewed:** 2026-08-16T18:20:57.530Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote native-binary bootstrap followed by automatic agent/editor hook setup - **Rationale:** This is a concrete install-time agent/editor integration lifecycle risk, not evidence of malicious exfiltration or a foreign control-surface hijack. Downgrade to warn because the postinstall executes an uninspectable remote native binary and automatically configures hooks. - **Files touched:** install.js, package.json, bin/autter.js, ~/.autter/bin/autter - **Network endpoints:** https://github.com/autter-dev/autter-cli/releases/download/${tag}/${file}, https://us.i.posthog.com/capture/ ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** postinstall runs install.js automatically., Installer downloads and executes a native binary, then invokes its install-hooks command., The install path explicitly sets up IDE/agent hooks and a daemon re-checks them daily. - **Evidence against:** Release URL is pinned to the package version and downloaded bytes are checksum-verified., Telemetry is documented as anonymous OS, architecture, and version data with an opt-out., No source evidence of credential harvesting, broad file collection, or exfiltration. ## Affected versions and remediation This report applies to @autter/cli@1.6.8. - Review the evidence and your use of @autter/cli@1.6.8 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
