The Cybersecurity Agency warns of new call scam tactics.

The Information Security Department under the Ministry of Information and Communications has issued a warning about a new, sophisticated scam called "call merging," which poses a potential risk of infiltrating and causing damage to Vietnamese users.

This scam, which has been warned about in many countries, has recently received special attention from the National Payment Systems Corporation of India (NPCI) because fraudsters exploit users' gullibility to steal OTP codes and misappropriate assets through online transactions.

A new call scam tactic called "call merging" has emerged (Illustrative image).

Accordingly, the scammer will directly call the victim, impersonating a friend and claiming to have obtained the phone number through a mutual friend. The name of this mutual friend is often found in the victim's social media friend list. Next, they will ask the victim to "merge the call" with this friend, which is actually a fraudulent call from the bank requesting the OTP code. When the victim agrees to participate in the merged call, the scammer easily obtains the OTP code and carries out unauthorized transactions on the victim's bank account.
