Easypaisa
Yesterday, I got a call from someone claiming to be from Easypaisa support. They warned me that my account was being hacked and asked for the "security code" sent to my phone to protect it.
In a rush, I shared the OTP. Within seconds, I got a text showing PKR 15,000 was deducted, and the caller hung up.
Tip: Never share your OTP with anyone!
