In-app chat scams have evolved significantly, becoming increasingly sophisticated and targeting users within trusted applications by exploiting features like chat interfaces to deceive them into divulging sensitive information. Scammers employ various tactics, from basic phishing and social engineering to advanced AI-driven chatbots, fake customer support impersonations, and app hijacking, often creating a false sense of urgency to prompt immediate action from users. These methods leverage the familiarity and trust users have in popular apps, making them particularly vulnerable to fraudulent schemes involving requests for personal information or financial transactions.
