In January 2026, we analyzed NFCShare, an Android banking trojan distributed as a malicious APK through a phishing flow impersonating Deutsche Bank. The malware presented a fake card-verification interface, asked the victim to place a payment card near the phone, collected the card PIN, and exfiltrated NFC-derived payment-card data to a WebSocket endpoint.
Since 14 May 2026, we have observed a newer wave of NFCShare APKs impersonating Italian and European banking brands. The campaign we investigated started from an ad hoc phishing website, areaclienti-intesa.com, which mimicked the look and feel of Intesa Sanpaolo. After the victim entered home-banking credentials, the phishing flow prompted the user to update the banking application. At that point, the website visually directed the victim to a shortened URL, such as https://tinyurl[.]com/Intesa-Carte, which then redirected toward APKs hosted in the GitHub repository antoniocastaldo1998/app-scuola.
The newer samples are still NFCShare. The core NFC and exfiltration logic remains largely unchanged. The relevant evolution is operational and anti-analysis oriented: more frequent APK rebuilds, brand rotation, a new C2 endpoint, a 10-DEX layout, and malformed ZIP paths designed to break naive APK extractors.
