My phone is updated with the latest security patches and I don't have Russian or Chinese ringtone apps on my phone.
How about "
cleaner", "
helper" or "
booster" apps? Even not Russian, Chinese or Khajiit.
From what happened, it looks like 'remote desktop-like malware' (
RAT) rather than a login credentials hack since Blockchain will require 2FA/email verification upon detecting another device/IP.
It wont for a few minutes if it's the same device and IP.
Anyways, once included in a block, a Bitcoin transaction cannot be reversed.
