Findings for this version do not establish the status of other versions. AI assessment: manual review; recommendation: manual review. This assessment is supporting evidence; the published decision above determines the current policy. Inspected source does not substantiate the scanner’s alleged encrypted payload execution or a concrete attack. The clean disposition is blocked by the required nine-path citation coverage exceeding the eight-citation limit, so this remains manual review rather than a malicious finding. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 63.0% - **Started:** 2026-10-08T00:11:07.893Z - **Finished:** 2026-10-08T00:11:51.484Z - **Download time:** 5367 ms - **Static scan time:** 10464 ms - **AI review time:** 27759 ms - **Total time:** 43591 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:** No concrete malicious attack surface was identified in the inspected code. The install hook extracts bundled platform utilities into the package directory, while the inspected agent-related paths do not establish hidden configuration mutation. - **Trigger:** npm installation triggers the postinstall unpacker; the CLI bridge runs when its command is launched. - **Impact:** The observed behavior is consistent with supplying utilities for the package and supporting its CLI. No exfiltration, remote payload execution, or unconsented foreign agent control-surface mutation was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-08T00:11:51.484Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The unpacker selects local platform archives and extracts them under tools/unpacked. The inspected configuration code reads settings and derives paths; the CLI wrapper imports the package-owned bridge. - **Rationale:** Inspected source does not substantiate the scanner’s alleged encrypted payload execution or a concrete attack. The clean disposition is blocked by the required nine-path citation coverage exceeding the eight-citation limit, so this remains manual review rather than a malicious finding. - **Files touched:** tools/unpacked - **Network endpoints:** https://claude.ai/oauth/authorize, https://console.anthropic.com/v1/oauth/token ### Review decision - **Verdict:** Manual Review - **Confidence:** 63.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The postinstall hook invokes an unpacker that extracts platform-specific bundled utilities into the package tools directory., The flagged settings code derives ordinary Claude configuration and project paths; the inspected excerpts show path selection and transcript-related helpers, not installation-time configuration mutation., The CLI MCP wrapper imports its package-owned bridge when launched, and the OAuth endpoints shown are Claude and Anthropic endpoints. - **Evidence against:** Static hints allege encrypted payload execution, but inspection found no corresponding decrypt-and-execute path in the main bundle; observed subprocesses are associated with CLI, git, platform, or daemon operations., The archive unpacker selects named platform archives and extracts them to tools/unpacked; no remote payload fetch or foreign agent configuration write was established. ## Affected versions and remediation This report applies to thalamus@1.5.50. - Review the evidence and your use of thalamus@1.5.50 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.
