The obfuscated CLI performs persistence prompting and runtime update/supervision. No install-time execution or confirmed unconsented control-surface mutation was established. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 84.0% - **Started:** 2026-08-09T14:10:43.962Z - **Finished:** 2026-08-09T14:11:39.466Z - **Download time:** 762 ms - **Static scan time:** 210 ms - **AI review time:** 54531 ms - **Total time:** 55504 ms ## Security analysis ### Published attack-surface review - **Summary:** The obfuscated CLI performs persistence prompting and runtime update/supervision. No install-time execution or confirmed unconsented control-surface mutation was established. - **Trigger:** User runs the whalent CLI. - **Impact:** Runtime-controlled updates and persistence behavior warrant caution, but no concrete malicious chain was proven. - **Evidence paths:** package.json, README.md, dist/index.cjs, dist/jupyter\_sidecar.py - **Review source:** ai\_review - **Reviewed:** 2026-08-09T14:11:39.466Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated runtime self-update and helper-release activation - **Rationale:** The package is highly obfuscated and has runtime update/persistence capabilities, creating unresolved lifecycle risk. It does not meet the blocking threshold because no install-time mutation or concrete malicious behavior was confirmed. - **Files touched:** dist/index.cjs, dist/core.cjs, dist/jupyter\_sidecar.py ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** dist/index.cjs is deliberately obfuscated., CLI runtime calls ensurePersistencePrompt before launching core., CLI runtime invokes maybeUpdateWrapper and supervises/restarts core., README documents runtime helper downloads and activation. - **Evidence against:** package.json has no preinstall/install/postinstall hook., The only lifecycle hook is prepublishOnly., jupyter\_sidecar.py is a local Jupyter NDJSON sidecar; no network client is present., No concrete credential-harvesting or foreign AI-agent config write was confirmed. ## Public findings ### 1.
