Truecaller, a widely used mobile application to screen callers and block spammers, has rolled-back its latest app update after discovering a bug which automatically enrolled customers for its payment service.

Late Monday evening, several users of the application took to social media platforms to complain about the latest update of the Trucaller app, which led to unauthorised access to other apps available on the user's phone.

The complaints alleged that the bug had prompted an unauthorised encrypted SMS to be sent from the user's phone to an unknown number for registration with truecaller's payment service. While users were registered with the UPI-based payment service, no actual transactions took place.

The bug, however, prompted concerns among users and forced the company to withdraw the update.

In a statement issued on social media platform Twitter, Truecaller said that “it had discovered a bug in the latest update of Truecaller the payments feature (India only), which automatically triggered a registration post updating to the version.” The company added that it has discontinued this version of the app so that no other users are affected, further stating that they have already rolled out a fix in a new version.

“For the users already affected, the new version with the update will be available shortly. In the meantime, users can choose to manually deregister their UPI ID from the banking/payment settings,” the statement said.
