Protect Wire Transfer Fields in Banking from Session Replay
In banking, wire transfer is one of the most targeted data types. Standard HTML inputs expose it to session replay attacks. SmartField encrypts it at the keystroke level.
The Risk
Wire Transfer entered in a standard form is immediately accessible:
// Session Replay attack:
document.querySelector('input').value
// "Wire Transfer data here" ← stolen
The Fix
<smart-field type="password" encrypt-key="/api/sf-key"
placeholder="wire transfer"></smart-field>
Now the same attack returns AES-256-GCM encrypted data. The wire transfer never exists as plaintext in the browser.
What the Attacker Gets
document.querySelector('smart-field').value
// "eyJ2IjoxLCJpdiI6IkNxT3..." ← 600+ chars of encrypted gibberish
Useless without your server's RSA-2048 private key.
Compliance
SmartField uses NIST-approved algorithms: AES-256-GCM (SP 800-38D) and RSA-2048 (SP 800-56B). Compatible with PCI-DSS, HIPAA, GDPR, SOX, and FISMA requirements.
Frequently Asked Questions
How does SmartField protect wire transfer in banking?+
SmartField encrypts wire transfer at the keystroke level using AES-256-GCM. The data never exists as plaintext in the browser DOM. Session Replay Protection is achieved through 13 independent security layers including closed Shadow DOM and WeakMap isolation.
Can session replay attacks steal wire transfer?+
Not with SmartField. The .value property returns encrypted payloads only. The real wire transfer is stored in a WeakMap inside a closed Shadow DOM, invisible to any JavaScript including session replay attacks.
How do I implement this?+
Replace your standard input with smart-field. 2 lines of HTML. Install the server SDK (Node.js, Python, Java, Go, PHP, or Ruby) to decrypt on your backend.
