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 is not a confirmed malicious install hook, but opaque automatic replacement of the running package is a real unresolved supply-chain risk. Warn rather than block because activation requires an explicit CLI invocation and no concrete harmful payload was established. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 89.0% - **Started:** 2026-09-12T07:43:36.268Z - **Finished:** 2026-09-12T07:44:51.081Z - **Download time:** 1034 ms - **Static scan time:** 204 ms - **AI review time:** 73574 ms - **Total time:** 74813 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 install-time attack was found. When the whalent CLI is run, its opaque wrapper can fetch version information, invoke npm to install another release, and restart into the resulting code. - **Trigger:** Running the whalent command. - **Impact:** A registry-selected later release can execute outside the reviewed artifact. - **Evidence paths:** dist/index.cjs - **Review source:** ai\_review - **Reviewed:** 2026-09-12T07:44:51.081Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated runtime self-update and respawn. - **Rationale:** This is not a confirmed malicious install hook, but opaque automatic replacement of the running package is a real unresolved supply-chain risk. Warn rather than block because activation requires an explicit CLI invocation and no concrete harmful payload was established. - **Files touched:** dist/index.cjs, dist/core.cjs ### Review decision - **Verdict:** Suspicious - **Confidence:** 89.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The manifest exposes dist/index.cjs as the executable CLI entry point., The CLI entry point is deliberately obfuscated and automatically checks for and installs a newer release with npm when the user runs the command., The wrapper can respawn itself after updating, creating a runtime-delivered code path that cannot be meaningfully audited from this release. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., The package does not declare itself as a runtime dependency., No concrete secret theft, destructive action, or foreign AI-agent configuration write was confirmed. ## Affected versions and remediation This report applies to @whalent/agent@0.3.420. - Review the evidence and your use of @whalent/agent@0.3.420 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.
