Call Merging Scam: What it is and How to Stay Safe

One would never think that a legitimate-sounding text message or call could land them in a scam. But it can, and it has. The National Payments Corporation of India (NPCI) has warned UPI users to be aware of a rising financial fraud: the call merging scam.

As fraudsters constantly find new ways to deceive individuals, citizens must stay vigilant against cyber criminals' crafty scam calls to protect themselves from their traps. Read to the end as we uncover the call merging scam and ways you can protect your financial peace of mind.

How does the call merging scam work?

Scammers have devised a new hack to bypass sensitive banking information, particularly the victims' OTP (one-time password), using a call-merging trick. Here’s how the cyber criminals execute the process.

  1. Builds trust with the victim

    The scammer creates a strong background to solidify their identity by portraying themselves as a customer service agent, job recruiter, mutual friend, representative of a renowned company, and so on. They weave their narrative carefully and present themselves as genuine to earn the victim’s trust.

  2. Requests to merge the call

    Once the victim is engrossed in the conversation, the scammer cunningly suggests a merge request to combine the call in the name of an official representative of the team or a said friend. The person on the second call carries on a natural, friendly conversation, which makes it hard to guess the second way. From there, the scammer takes control of the fake number without the victim realising that it is an OTP scam.

  3. Linking to an OTP call trap

    Here’s where things go haywire. The second call, which claims to be legitimate, is not from an official representative but is connected to an automated OTP verification call from the victim’s bank.

  4. Tricking to share OTP

    The scammer manipulates the victim into sharing sensitive information, such as OTP and banking details, for verification purposes. As trust deepens and the conversation becomes more convincing, the scammer easily gains access to victims' information and bank accounts.

  5. The victim’s financial loss

    The moment the OTP is shared, the scammer initiates fraudulent transactions, though misguided, willingly, leaving the victim puzzled. Additionally, recovering from financial loss becomes difficult since users voluntarily authorise and complete the transactions.

How can you make yourself cyber-safe?

The following are the key takeaways to keep in mind to protect yourself from a call merging scam.

  1. Watch out for unknown calls

    If you receive a call from an unfamiliar person who offers you discounts or prizes that seem too good to be true, be cautious, as these are tactics for them to catch hold of their prey. Avoid having long conversations and disconnect the call when you find the matter is fishy.

  2. Do not share OTP over the phone

    Banks never ask for OTPs or key financial information over the phone and use tactics to rush you into making decisions. Be alert, as this is a major red flag indicating an OTP scam.

  3. Verify the caller’s identity

    If someone pretends to be your friend or a bank representative, cross-check their background. Call the official helpline or customer care number, or contact your friend directly to confirm the caller’s identity.

  4. Use identity verification apps

    Always be ahead of the scammers. Use apps or software that detect potential spam calls and flag scam numbers. These will help you avoid falling prey to scammers' fraudulent activities and keep you safe from any financial loss.

  5. Monitor your accounts regularly

    Monitor your transactions regularly and keep a record of your accounts. This will help you plan your budgets effectively, keep you aware of your financial well-being, and alert you in case of any discrepancies or financial mishaps.

  6. Report suspicious activities

    If you receive an unexpected OTP for a transaction you didn’t initiate, please call 1930 immediately. It is the official National Cybercrime Helpline number, and your bank account will be informed immediately. Never redirect to suspicious links and numbers, as these are traps to lure in unsuspecting victims.
