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. The package has no install-time lifecycle hook, but its normal CLI entrypoint performs an opaque self-update through npm and permits scripts. This is a dangerous active capability rather than confirmed malware. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-09-22T06:47:45.481Z - **Finished:** 2026-09-22T06:57:12.899Z - **Download time:** 1011 ms - **Static scan time:** 187 ms - **AI review time:** 566220 ms - **Total time:** 567418 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 activates an opaque automatic updater. It can globally install a newer wrapper release and permit selected lifecycle scripts. - **Trigger:** A user runs the whalent command. - **Impact:** A future registry release and its allowed scripts can execute in the user's environment without a separate update command. - **Evidence paths:** dist/index.cjs - **Review source:** ai\_review - **Reviewed:** 2026-09-22T06:57:12.899Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The entrypoint calls maybeUpdateWrapper, which uses safeSpawnSync to run a global npm install for WRAPPER\_PKG\_NAME at a resolved version with whalentRuntimeAllowScriptsArg. - **Rationale:** The package has no install-time lifecycle hook, but its normal CLI entrypoint performs an opaque self-update through npm and permits scripts. This is a dangerous active capability rather than confirmed malware. ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **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 entrypoint and contains no install lifecycle hook., The executable entrypoint automatically calls its wrapper update routine when the CLI runs., The update routine invokes a global npm install for the wrapper package and supplies an argument enabling selected package scripts., The executable is deliberately obfuscated, preventing transparent inspection of its update and persistence paths. - **Evidence against:** No preinstall, install, or postinstall hook is declared in the manifest., No concrete credential collection or exfiltration endpoint was established from the inspected entrypoint. ## Affected versions and remediation This report applies to @whalent/agent@0.3.366. - Review the evidence and your use of @whalent/agent@0.3.366 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.
