How Scammers Steal Data From Legitimate Websites
You don't have to visit a shady website to have your financial details stolen. In a attack called form-jacking or Magecart, cybercriminals hack into legitimate online stores and inject invisible scripts into the checkout page.
When you type your credit card number, home address, or Social Security number into what looks like a completely normal payment form, the hidden script sends a copy of your information directly to the hacker's server.

Key Takeaway
Form-jacking occurs on real, legitimate shopping sites that have been compromised by hackers.
What is Data Loss Prevention (DLP)?
Data Loss Prevention (DLP) is like a digital vault monitor that watches over your sensitive numbers. Instead of trusting every webpage, your browser constantly checks what kind of information is being submitted.
If a form tries to send a valid credit card number, Social Security number, or sensitive private key without your explicit permission, the DLP system flags it and prevents the leak.

Key Takeaway
DLP inspects web form submissions right on your computer to ensure sensitive personal data isn't leaked.
Privacy-Preserving On-Device Data Loss Prevention
BrowserShield includes built-in Data Loss Prevention that scans form inputs locally in device memory at the moment of submission. Built on strict zero-telemetry privacy architecture, it also guards against clipboard hijacking data theft.
It uses smart mathematical verification (such as the Luhn algorithm for credit card numbers) to recognize sensitive data patterns instantly. Paired with Clipboard Protection against copy-paste theft, your typed information is never uploaded to BrowserShield servers—sensitive numbers are evaluated on-device before submission.
