React UI components and hooks for EmbarkAI authentication and Account Abstraction
AI Security Review
scanned 4mo ago · by lpm-firewall-aiStatic inspection shows suspicious primitives are attributable to browser wallet/auth functionality: bundled wasm-bindgen glue, user-invoked OAuth/backup/network calls, and iframe messaging. There is no lifecycle execution, hidden exfiltration, remote decoded code execution, persistence, destructive action, or AI-agent control-surface mutation.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
User imports the UI kit and invokes provider/auth/wallet/backup/OAuth flows in a browser.
Impact
Expected auth, wallet signing, keyshare backup/restore, and UI behavior; no unconsented install-time execution or credential harvesting found.
Mechanism
Package-aligned browser fetch, iframe postMessage, localStorage, OAuth popup, and bundled WASM crypto operations.

Decision evidence
public snapshotAI called this Clean at 86.0% confidence as Benign with medium false-positive risk.
Evidence for AI clean decision
- dist/iframe/main.js ships dkls23_wasm_bg.wasm and wasm-bindgen glue with new Function/module.require imports.
- dist/index.cjs and dist/iframe/main.js send auth tokens/keyshare data to EmbarkAI vault/TSS APIs during wallet backup/auth flows.
- dist/iframe/oauth/telegram.js loads Telegram widget and posts OAuth result to opener with wildcard target.
Evidence against
- package.json has no install/preinstall/postinstall lifecycle hooks; scripts are build/dev only.
- dist/index.cjs import-time action only injects packaged CSS into document head when a browser document exists.
- Network calls are aligned with UI wallet/auth, backup, bridge, explorer, and OAuth features and are user/runtime invoked.
- dist/iframe/main.js fetches local dkls23_wasm_bg.wasm via import.meta.url; no remote decoded payload found.
- No child_process usage found; scanner hit appears to be noisy.
- postMessage handling checks iframe origin for SDK messages and OAuth popup origins are constrained by iframe origin in caller.

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