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. 27 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:** 1.5.61 - **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 agent-related excerpts do not establish a malicious action, and the postinstall script shows local archive extraction. The required archive is non-UTF-8 and cannot be assessed from source; this unresolved required artifact prevents a clean decision, while the inspected source does not independently establish a warning or attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 63.0% - **Started:** 2026-10-09T07:58:25.381Z - **Finished:** 2026-10-09T07:59:15.526Z - **Download time:** 6698 ms - **Static scan time:** 11079 ms - **AI review time:** 32367 ms - **Total time:** 50145 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 was identified in the inspected executable source. The postinstall hook unpacks a bundled archive, but the archive’s contents could not be evaluated as UTF-8 source. - **Trigger:** npm installation triggers the package postinstall hook. - **Impact:** The archive contents remain unresolved, so static source inspection cannot establish whether the extracted binaries are benign or harmful. - **Evidence paths:** package.json, scripts/unpack-tools.cjs, tools/archives/difftastic-arm64-linux.tar.gz - **Review source:** ai\_review - **Reviewed:** 2026-10-09T07:59:15.526Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook selects a platform-specific archive and extracts it into the package tools directory. - **Rationale:** The inspected agent-related excerpts do not establish a malicious action, and the postinstall script shows local archive extraction. The required archive is non-UTF-8 and cannot be assessed from source; this unresolved required artifact prevents a clean decision, while the inspected source does not independently establish a warning or attack. - **Files touched:** scripts/unpack-tools.cjs, tools/archives/difftastic-arm64-linux.tar.gz ### Review decision - **Verdict:** Manual Review - **Confidence:** 63.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The package has a postinstall hook that runs a local tool-unpacking script; the inspected script selects a platform archive and extracts it into the package tools directory., The named agent configuration locations inspect Claude settings and project paths; the inspected excerpts do not establish a configuration write or plugin installation., The MCP launcher starts its package-local bridge and forwards arguments and environment to it., A required compressed archive is non-UTF-8 and cannot be assessed through source citations; static inspection does not establish what it contains. - **Evidence against:** The postinstall script’s shown behavior extracts platform-specific archives shipped with the package rather than fetching a remote payload., The inspected agent-configuration excerpts show path selection and memory-override checks, not agent-control mutation. ## Affected versions and remediation This report applies to thalamus@1.5.61. - Review the evidence and your use of thalamus@1.5.61 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.
