That's not what's happening though? It's relaying a physical card's nfc not tricking mobile contactless payments
That's what I mean, it shouldn't be possible to relay anything. It should only trigger when there's a reader physically in proximity to the phone.
Please keep in mind this is happening on the victim's phone which is not rooted, the malware is a regular non-system app.
If it were happening on a rooted phone I could understand being able to subvert the NFC chain because at some point it has to pass from hardware to software and if you're privileged enough you can cut in there. But the malware app is not privileged.
When it happens it's a security flaw and it needs to get patched. It's not normal everyday thing.
