Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 28 low-signal pattern(s) reviewed. - **Verdict:** Manual Review - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Under Review - **Threat category:** Unknown - **Selected version:** 1.5.66 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. 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. The inspected source locations do not substantiate the scanner’s alleged encrypted-payload execution or agent-control mutation. The shipped binary archive cannot be cleared through source inspection, so the package remains unresolved. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 72.0% - **Started:** 2026-10-11T08:01:51.976Z - **Finished:** 2026-10-11T08:02:50.417Z - **Download time:** 3603 ms - **Static scan time:** 14938 ms - **AI review time:** 39899 ms - **Total time:** 58441 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 attack behavior was established in the inspected source excerpts. The packaged compressed binary archive remains unverified. - **Trigger:** The package postinstall hook runs during installation and unpacks a platform-specific archive. - **Impact:** No attack impact was confirmed; the unverified archive prevents a clean determination. - **Review source:** ai\_review - **Reviewed:** 2026-10-11T08:02:50.417Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The inspected hook extracts bundled tools; the inspected flagged code reads Claude project transcripts or writes friction metrics. The archive contents could not be verified as source. - **Rationale:** The inspected source locations do not substantiate the scanner’s alleged encrypted-payload execution or agent-control mutation. The shipped binary archive cannot be cleared through source inspection, so the package remains unresolved. - **Files touched:** scripts/unpack-tools.cjs, tools/archives/difftastic-arm64-linux.tar.gz ### Review decision - **Verdict:** Manual Review - **Confidence:** 72.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The install hook is a platform-specific tool unpacker; the inspected code extracts a packaged archive into the package tools directory., The flagged API locations read Claude project transcript files, and the flagged index locations compute and write friction metrics., The package also ships a compressed binary archive whose contents cannot be verified with source citations. - **Evidence against:** The inspected agent-related code reads Claude project data or writes metrics under the package’s configured data directory; these excerpts do not establish an agent-control mutation., The package manifest identifies the product as a Claude Code client and registers a postinstall tool unpacker. ## Affected versions and remediation This report applies to thalamus@1.5.66. - Review the evidence and your use of thalamus@1.5.66 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.
