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. This package does not contain an npm install hook or a self-dependency, but its obfuscated runtime global updater with lifecycle-script allowance is a concrete unresolved execution risk. Static inspection cannot establish malicious intent or a confirmed payload. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 84.0% - **Started:** 2026-09-07T15:22:32.404Z - **Finished:** 2026-09-07T15:23:34.055Z - **Download time:** 255 ms - **Static scan time:** 250 ms - **AI review time:** 61144 ms - **Total time:** 61651 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:** Running the whalent CLI can trigger an opaque wrapper-update path that launches npm to install a package globally. Obfuscation prevents confirming the full package selection and subsequent behavior. - **Trigger:** A user runs the whalent CLI. - **Impact:** A later registry package and its allowed lifecycle scripts could execute in the user's global npm environment. - **Evidence paths:** dist/index.cjs - **Review source:** ai\_review - **Reviewed:** 2026-09-07T15:23:34.055Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated runtime global npm update through a child process. - **Rationale:** This package does not contain an npm install hook or a self-dependency, but its obfuscated runtime global updater with lifecycle-script allowance is a concrete unresolved execution risk. Static inspection cannot establish malicious intent or a confirmed payload. - **Files touched:** dist/index.cjs ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The published CLI entry point and its 16 MB core bundle are deliberately string and control-flow obfuscated, which prevents meaningful static verification of their behavior., When the CLI runs, the wrapper invokes npm with a global install argument for a wrapper package and enables selected lifecycle scripts., The executable can run child processes and carries an opaque remote-update mechanism, leaving a supply-chain execution surface that cannot be safely resolved from the shipped source. - **Evidence against:** package.json has no preinstall, install, or postinstall hook; its only lifecycle-like hook is prepublishOnly., The manifest has no dependency on its own package name., No concrete credential theft, destructive command, or exfiltration endpoint was recoverable from the inspected source. ## Affected versions and remediation This report applies to @whalent/agent@0.3.407. - Review the evidence and your use of @whalent/agent@0.3.407 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.
