@yieldfabric/wallet@0.2.1
Reusable YieldFabric wallet — login, signing, profile, and key management
AI Security Review
scanned 2d ago · by lpm-firewall-aiThe README contains an explicit instruction that attempts to constrain source review. The inspected network and credential behavior otherwise aligns with the package’s wallet SDK purpose, and no install-time hook was declared.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
A reviewer reads the README or bundled entrypoint header.
Impact
Could suppress or constrain independent security analysis.
Mechanism
The text asserts that source review needs vendor authorization and is limited to visual inspection.
Attack narrative
The README and entrypoint header tell reviewers that source inspection requires vendor authorization and impose a visual-inspection-only limit. This is review-directed text and is treated as malicious reviewer manipulation under the review rules.
AI rationale
The README contains an explicit instruction that attempts to constrain source review. The inspected network and credential behavior otherwise aligns with the package’s wallet SDK purpose, and no install-time hook was declared.
Evidence
README.mddist/index.js
Decision evidence
public snapshotAI called this Malicious at 97.0% confidence as Malware with low false-positive risk.
Evidence for block
- The README tells reviewers that source review requires the vendor’s signed authorization and that review access permits visual inspection only, attempting to constrain this security review.
Evidence against
- The package describes itself as a wallet SDK for login, signing, profile, and key management.
- Login credentials are sent through the SDK’s auth login method, and service URLs are configurable with localhost defaults.
- The manifest exposes bundled JavaScript entrypoints and declares no install, preinstall, or postinstall hook.
