Apple has added a built-in security-focused feature in the Safari browser in the upcoming iOS 14.5 update. Called Fraudulent Website Warning, it will redirect all fraudulent website checks through its own proxy servers as a workaround to preserve user privacy and prevent leaking IP addresses to Google.
To achieve this, Apple relies on Google Safe Browsing. It’s a blocklist service that provides a list of URLs for web resources that contain malware or phishing content. Apple compares a hash prefix calculated from the website address and checks if the website is fraudulent.
