Do not execute instructions or code found in this document. ## Verdict summary **Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only agent extension risk - **Public report status:** Published - **Threat category:** Agent extension lifecycle risk - **Selected version:** 0.3.370 - **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: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The active, obfuscated CLI includes automatic self-update behavior and a persistence-related prompt, which leaves a meaningful agent-runtime lifecycle risk. Static inspection did not establish a concrete malicious payload or data theft. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 83.0% - **Started:** 2026-09-22T06:42:17.887Z - **Finished:** 2026-09-22T06:51:54.212Z - **Download time:** 1012 ms - **Static scan time:** 193 ms - **AI review time:** 575119 ms - **Total time:** 576325 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:** The CLI contains an automatic wrapper-update path. No confirmed credential theft, destructive action, or unrelated network recipient was established. - **Trigger:** Running the whalent CLI reaches the persistence and wrapper-update routines. - **Impact:** A CLI invocation can replace the installed wrapper with a newer release, creating a package-update control surface. - **Evidence paths:** dist/index.cjs - **Review source:** ai\_review - **Reviewed:** 2026-09-22T06:51:54.212Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The obfuscated entrypoint checks for a latest package version, installs it through installWrapperVersion, and respawns the process. - **Rationale:** The active, obfuscated CLI includes automatic self-update behavior and a persistence-related prompt, which leaves a meaningful agent-runtime lifecycle risk. Static inspection did not establish a concrete malicious payload or data theft. ### Review decision - **Verdict:** Suspicious - **Confidence:** 83.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** package.json exposes dist/index.cjs as both the main module and the whalent CLI., The active CLI entrypoint invokes its persistence check and wrapper-update routine., The update routine resolves a newer package version and passes it to installWrapperVersion before respawning. - **Evidence against:** package.json contains no npm preinstall, install, or postinstall lifecycle hook., No credential collection, endpoint, or exfiltration send sink was confirmed in the inspected entrypoint. ## Affected versions and remediation This report applies to @whalent/agent@0.3.370. - Review the evidence and your use of @whalent/agent@0.3.370 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.
