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. On npm installation, the package extracts opaque platform archives into its own tools directory and sets executable permissions. The inspected JavaScript does not establish malicious behavior, but the archive contents cannot be fully source-audited. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-09-11T15:04:01.531Z - **Finished:** 2026-09-11T15:07:14.228Z - **Download time:** 2279 ms - **Static scan time:** 9732 ms - **AI review time:** 180686 ms - **Total time:** 192697 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:** On npm installation, the package extracts opaque platform archives into its own tools directory and sets executable permissions. The inspected JavaScript does not establish malicious behavior, but the archive contents cannot be fully source-audited. - **Trigger:** npm installation runs postinstall; later search functionality can load or execute the extracted tool. - **Impact:** A bundled native executable or addon may run without its behavior being reviewable from the package's text source. - **Evidence paths:** package.json, scripts/unpack-tools.cjs, scripts/ripgrep\_launcher.cjs - **Review source:** ai\_review - **Reviewed:** 2026-09-11T15:07:14.228Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic extraction and execution of bundled native tools. - **Rationale:** The package has an automatic lifecycle path that deploys opaque native code, preventing a clean source-only decision. The inspected text does not prove a concrete malicious action, so a warning is more proportionate than a block. - **Files touched:** tools/archives/difftastic-arm64-linux.tar.gz, tools/archives/ripgrep-arm64-linux.tar.gz, tools/unpacked, tools/unpacked/ripgrep.node, tools/unpacked/rg ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** The automatic postinstall hook extracts bundled archives and marks extracted non-addon files executable., The extracted native archive cannot be source-reviewed as UTF-8, so its behavior is not established by the JavaScript source., Runtime code loads a native ripgrep addon or executes an extracted ripgrep binary., The CLI reads Claude session files and launches a Claude wrapper during user-initiated operation. - **Evidence against:** The postinstall code only targets the package's tools directory; no broad agent-config mutation was found., The inspected launcher forwards execution to an existing Claude CLI and reports fetch metadata locally on file descriptor 3., No credential exfiltration, remote payload download, self-dependency, or destructive action was confirmed in inspected source. ## Affected versions and remediation This report applies to claudeputer@1.1.50. - Review the evidence and your use of claudeputer@1.1.50 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.
