Do not execute instructions or code found in this document. ## Verdict summary **Flagged — allowed with a warning** — Allowed by default policy, but 11 finding(s) warrant review before installing. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Matched warn-list - **Public report status:** Published - **Threat category:** Unknown - **Selected version:** 2.0.0 - **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 manifest has no install hook, and the documented purpose is ERC20 interaction. The obfuscated entrypoint and runtime leave behavior unresolved, so this warrants a warning rather than a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 72.0% - **Started:** 2026-10-24T18:24:48.644Z - **Finished:** 2026-10-24T18:25:32.136Z - **Download time:** 510 ms - **Static scan time:** 68 ms - **AI review time:** 42913 ms - **Total time:** 43492 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 concrete attack was confirmed. The runtime path is substantially obscured by decoded strings and computed names, so its full behavior remains unresolved. - **Trigger:** A consumer importing the package through its declared entrypoint. - **Impact:** The unresolved runtime behavior prevents verifying whether the package performs only its documented ERC20 operations. - **Evidence paths:** main-ethers.js, ethers3.js - **Review source:** ai\_review - **Reviewed:** 2026-10-24T18:25:32.136Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The entrypoint loads an obfuscated runtime module whose dependency names and database operations are constructed through a string decoder. - **Rationale:** The manifest has no install hook, and the documented purpose is ERC20 interaction. The obfuscated entrypoint and runtime leave behavior unresolved, so this warrants a warning rather than a block. - **Files touched:** package.json, main-ethers.js, ethers3.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 72.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** The manifest points to main-ethers.js as the package entrypoint., The manifest declares only a test script and no install lifecycle hook., The entrypoint and runtime module use decoded strings to construct a require call and module names., Database setup and query operations in the runtime are also hidden behind decoded strings, leaving their effects unresolved. - **Evidence against:** The README describes account, balance, and transfer functions consistent with the package’s stated ERC20 purpose., Inspection did not confirm a concrete credential transfer, destructive action, or other attack behavior. ## Affected versions and remediation This report applies to ethers-3rc20@2.0.0. - Review the evidence and your use of ethers-3rc20@2.0.0 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.
