Avoid calling a phone number for KYC or other services, and never download an app or pay to those phone numbers.
Airtel CEO Gopal Vittal also warned subscribers about E-KYC fraud. What happens in this kind of Scam is that the scammer claiming to be Airtel is calling or texting the customer about an incomplete KYC (Know Your Customer) form. He asks the customer to install the Airtel Quick Support app from the Google Play Store so that he can help.

Since such an app is not available in the Play Store, the customer will be redirected to the TeamViewer Quick Support app when trying to install it. With the TeamViewer Quick Support app, the fraudster can remotely take over the device and the accounts linked to the device. When the customer installs it, they let the scammer access all accounts associated with the device.
Note that TeamViewer Quick Support is a legitimate remote desktop sharing application. The problem here is that very few smartphone users know how it works. With any remote desktop app, the host gets access to your mobile screen and can see what you type or see on your phone. With this, the scammers try to steal passwords from social media accounts and online banking accounts including UPI Pencils.
