React UI components and hooks for EmbarkAI authentication and Account Abstraction
AI Security Review
scanned 4mo ago · by lpm-firewall-aiThe scanner's critical remote decode/execute signal appears to conflate packaged WASM loading and wasm-bindgen glue with malicious dynamic execution. Static inspection found no install-time execution, exfiltration, shell execution, destructive behavior, or unauthorized persistence beyond expected browser localStorage for the SDK.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
User imports SDK components or opens the bundled iframe/social/KYC flows in a browser app.
Impact
Expected handling of access tokens, keyshare data in iframe localStorage, OAuth/KYC data, and wallet operations within user-invoked flows.
Mechanism
Browser auth wallet SDK with packaged WASM and API requests

Decision evidence
public snapshotAI called this Clean at 89.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- dist/iframe/main.js ships dkls23_wasm_bg.wasm and wasm-bindgen glue using WebAssembly plus new Function.
- dist/index.cjs and dist/iframe/main.js send auth-bearing requests to EmbarkAI/TSS/on-ramp APIs and some third-party OAuth/Google endpoints.
Evidence against
- package.json has no preinstall/install/postinstall/prepare lifecycle hooks; scripts are build/dev utilities only.
- main/module exports are React UI/auth SDK bundles; import-time code mostly defines modules and constants.
- dist/iframe/main.js new Function is wasm-bindgen/lodash glue, not decoded remote payload execution.
- WASM is loaded from packaged dist/iframe/dkls23_wasm_bg.wasm via import.meta.url, not an arbitrary remote asset.
- Network calls align with wallet auth, TSS, iframe, OAuth, KYC, balance, and on-ramp features described by package/README.
- No child_process use, filesystem harvesting, persistence outside browser storage, destructive actions, or AI-agent control-surface writes found.

Remote Asset Decode Execute
Source fetches a remote non-code asset, decodes its contents, and dynamically executes the decoded payload.
