Scammers are exploiting WhatsApp's screen sharing feature to trick users into revealing one-time passwords (OTPs) and stealing funds. Attackers initiate screen sharing sessions under false pretenses, gaining real-time visibility into sensitive information such as OTPs used for two-factor authentication. This social engineering tactic bypasses technical controls by manipulating user trust and interaction. The threat primarily targets individuals but can have broader implications for organizations relying on WhatsApp for communication or authentication. No direct software vulnerability is exploited; rather, the attack leverages user behavior and the screen sharing capability. The ease of exploitation is moderate, requiring user interaction and deception. European organizations with employees or clients using WhatsApp are at risk, especially in countries with high WhatsApp penetration. Mitigation involves user education, strict policies on screen sharing, and alternative secure authentication methods. The threat is assessed as medium severity due to its impact on confidentiality and potential financial loss, despite requiring user cooperation.
