Its Jupyter sidecar can execute protocol-supplied Python, but no concrete unconsented attack chain was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 83.0% - **Started:** 2026-08-22T01:50:20.893Z - **Finished:** 2026-08-22T01:51:41.434Z - **Download time:** 1015 ms - **Static scan time:** 231 ms - **AI review time:** 79294 ms - **Total time:** 80541 ms ## Security analysis ### Published attack-surface review - **Summary:** Runtime invocation launches an obfuscated CLI wrapper with update/core-selection behavior. Its Jupyter sidecar can execute protocol-supplied Python, but no concrete unconsented attack chain was found. - **Trigger:** User invokes the whalent CLI or sends an execute request to its sidecar. - **Impact:** Opaque runtime updates could change executable behavior; no specific exfiltration, persistence, or destructive action was confirmed. - **Evidence paths:** package.json, dist/index.cjs, dist/core.cjs, dist/jupyter\_sidecar.py - **Review source:** ai\_review - **Reviewed:** 2026-08-22T01:51:41.434Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** obfuscated runtime wrapper and requested code execution - **Rationale:** The package is not proven malicious, but its obfuscated executable bundles and runtime-update path prevent a trustworthy clean determination. Warn rather than block because activation is runtime/user-driven and no concrete attack behavior was established. - **Files touched:** dist/index.cjs, dist/core.cjs, dist/jupyter\_sidecar.py ### Review decision - **Verdict:** Suspicious - **Confidence:** 83.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** The CLI entrypoint is heavily obfuscated, preventing normal source audit., Obfuscated runtime code includes wrapper-update and alternate core-entry logic., The bundled sidecar executes Python supplied through its runtime protocol. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., The exposed sidecar protocol requires an explicit execute request; no unsolicited exfiltration or destructive action was identified., No concrete credential harvesting, foreign AI-agent config mutation, or fixed malicious endpoint was established. ## Public findings ### 1.
