## Security analysis

### Published attack-surface review

- **Summary:** Calling the exported connect() sends caller-supplied data in a GET path to an obfuscated remote base URL. No install-time or import-time trigger was found.

- **Trigger:** Consumer explicitly invokes the exported connect() function.

- **Impact:** Caller input may be disclosed to an undisclosed endpoint.

- **Evidence paths:** package.json, README.md, index.js

- **Review source:** ai\_review

- **Reviewed:** 2026-07-30T11:02:54.078Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** Obfuscated outbound HTTP GET via axios.

- **Rationale:** The concealed outbound request and unrelated package documentation create unresolved security risk, but the source does not establish automatic theft or another concrete malicious chain.

- **Files touched:** index.js

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 87.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Unknown

- **False-positive risk:** Low

- **Evidence for:** index.js is deliberately obfuscated., index.js imports axios and builds a hidden API\_BASE\_URL., Exported connect() performs an axios GET to that URL plus caller input., README.md references a different package: evm\_account.

- **Evidence against:** package.json has no lifecycle hooks., Network call is only in exported connect(), not import-time., No source evidence of env/file harvesting, shell execution, or persistence.
