⚔️ Metodología de Ataque

Primary Method: Impersonation

The site uses the WhatsApp brand and logo to trick users into believing a fake lottery is legitimate, with the goal of obtaining sensitive data or installing malware. This is a common social engineering tactic.

Secondary Method: Social Engineering

The site uses promises of prizes and rewards ('undian') to create a sense of urgency and excitement, encouraging users to take actions that they normally wouldn't.
