Remove SuperCard X Android Malware

SuperCard X is a sophisticated Android malware that targets users primarily in Italy. It exploits Near Field Communication (NFC) technology to perform real-time relay attacks, allowing cybercriminals to carry out unauthorized transactions using victims’ payment cards. Distributed through Malware-as-a-Service (MaaS), it spreads via deceptive social engineering tactics such as smishing (SMS phishing) and fraudulent phone calls. Victims are tricked into installing malicious applications disguised as legitimate security tools.

Threat Overview

SuperCard X tricks users into installing a malicious app that acts as a fake security verifier. Once installed, the app captures data from the victim’s NFC-enabled payment card when placed near the device. This information is relayed to an attacker’s device, which then emulates the victim’s card to execute fraudulent transactions via Point-of-Sale systems or ATMs.

Threat Summary

In-Depth Analysis

How Did I Get Infected?

Infection typically begins with a deceptive SMS or WhatsApp message posing as a security alert from your bank. The message urges the recipient to call a phone number. Once connected, scammers impersonating bank employees instruct the victim to install a fake “security” app. When the victim brings their payment card close to the infected phone, the app captures NFC data, unknowingly handing it over to the attacker.

What Does It Do?

The malware uses the NFC data collected from the victim’s card and transmits it to a second device operated by the cybercriminal. This device uses a companion app to mimic the card, allowing it to make purchases or withdraw money. The communication between devices is secured using encryption protocols, and the app requests minimal permissions to avoid suspicion, helping it evade detection.

Should You Be Worried for Your System?

Yes. SuperCard X is highly dangerous due to its ability to execute real-time payment fraud through contactless technology. Users who frequently use NFC payments are especially at risk. Its use of social engineering and advanced communication encryption makes detection and prevention challenging without professional tools.
