SuperCard X is a stealthy Android malware that uses a phone's NFC reader to steal card data and enable instant fraud. Spread via social engineering through SMS or WhatsApp, it tricks users into installing a fake app. Once the victim taps their card on the infected phone, the malware relays card data in real time to an attacker’s device, enabling immediate unauthorized transactions. It’s hard to detect due to low permissions and highlights the need for strong security awareness and real-time threat monitoring.
