In what looks like the making of a massive scam, Indian Android users of popular caller ID app 'Truecaller' woke up on Tuesday to a worrying message. Users reported receiving an SMS that read, "Your registration for UPI app has started". The app is supposedly creating UPI accounts with ICICI Bank without user consent. The issue began following the app's latest update. Truecaller had partnered with ICICI bank in 2017 to launch UPI-based mobile payment service, Truecaller Pay. HuffPost India quoted Trucaller, as saying, that this is being caused by a bug that affects the payments feature.
