Analyst notes

NFC Relay (provisional). Android NFC-relay fraud malware. Running on a victim’s phone, it reads contactless bank-card/tag data over NFC and relays it in real time over a WebSocket channel to an attacker-controlled device, which replays it at a payment terminal or ATM for fraudulent transactions (an NFSkimming / “NGate”-style technique). Observed C2 infrastructure includes dashboardcloud.app / api.dashboardcloud.app, dashboard.gripe and 178.236.243.8. Family label provisional. Indicators: wss://dashboard.gripe/ws-relay, https://dashboardcloud.app, https://api.dashboardcloud.app/api/status.
