Fraudulent Claims

⚔️ Attack Methodology

Primary Method: Credential Harvesting

The site attempts to imitate the Nubank website to deceive users into providing personal or financial credentials. This is made possible via the registration of a similar looking domain and the obfuscation of the site's code to hide malicious activity.

Secondary Method: Social Engineering

The site uses design elements and branding to mislead users into believing it is a legitimate site.
