PNB AI Cyber Fraud Alert: Beware of Fake Calls as Punjab National Bank (PNB) warns customers about increasingly sophisticated scams involving artificial intelligence (AI).
Fraudsters are using voice cloning, deepfake technology and phishing messages to impersonate trusted people or make fake communications appear genuine.
The public sector bank issued the warning on October 20, 2026, urging customers to remain vigilant and verify suspicious calls and messages before taking action.
The alert comes as cybercriminals increasingly exploit people’s trust, fear and sense of urgency to pressure them into transferring money or sharing sensitive information.
PNB AI Cyber Fraud Alert: How Scammers Operate
One of the major threats highlighted by PNB is AI-powered voice cloning.
This technology can imitate a person’s voice, potentially allowing fraudsters to pose as a family member, friend or another trusted individual and demand money under false pretences.
For example, a scammer could pretend to be a relative facing an emergency and ask for an immediate money transfer.
the caller may sound familiar, the victim could feel pressured to act without checking whether the situation is genuine.
Deepfake technology presents another risk. Fraudsters can use AI-generated or manipulated audio and video to make false identities or claims appear more convincing, increasing the chances that victims will believe a fabricated emergency.
Phishing is also a concern. Fake emails, SMS messages and other digital communications may closely resemble legitimate bank messages, making it difficult for customers to distinguish genuine communication from an attempt to steal personal or financial information.
Why Customers Should Not Rush Into Money Transfers
According to the warning, many cyber frauds rely on human behaviour rather than technology alone.
Criminals create panic, exploit trust and impose artificial deadlines to discourage victims from verifying information independently.
A message claiming that an account will be blocked shortly or a call demanding urgent payment should therefore be treated cautiously.
Customers should avoid making financial decisions simply because a caller insists that immediate action is necessary.
Cybersecurity experts have advised people to pause, end suspicious calls and independently contact the person concerned using a number already saved in their phone.
This can help establish whether the request is genuine rather than relying on the caller’s identity or the information provided during the conversation.
Families can also agree on a private code word known only to trusted members.
someone calls claiming to be a relative in distress, asking for the agreed code word can provide an additional way to check the person’s identity.
Steps to Protect Your Bank Account From AI Scams
Customers can take several practical steps to reduce their exposure to digital fraud. The first is to enable two-factor authentication for banking, email and social media accounts wherever available.
This adds another layer of security beyond a password.
Using different, strong passwords for separate accounts is equally important. Reusing the same password across multiple services can increase the damage if one account is compromised.
Customers should also consider setting daily transaction limits for UPI and card payments.
These limits can help restrict potential losses if an unauthorised transaction occurs, although they cannot prevent every type of fraud.
Suspicious links and unexpected requests for sensitive information should be avoided.
Customers should never disclose their PIN, password or OTP to someone who contacts them unexpectedly, even if the caller claims to represent a bank or another trusted organisation.
People should also download banking applications only from authorised app stores and keep their devices and applications updated.
PNB’s cybersecurity guidance similarly stresses verifying the authenticity of communications and reporting suspicious activity promptly.
Digital Awareness Is Essential as AI Scams Evolve
October is observed as National Cyber Security Awareness Month, making the warning particularly relevant as banks and cybersecurity professionals highlight the importance of safer digital habits.
AI tools can make fraudulent communications more convincing, but customers can reduce their risk by independently verifying unusual requests, protecting account credentials and refusing to act under pressure.
PNB has reiterated that cybersecurity is a shared responsibility between financial institutions and their customers.
While banks work to strengthen their security systems, customers also need to remain alert to unfamiliar calls, suspicious messages and requests for urgent payments.
The key lesson from the PNB AI Cyber Fraud Alert is simple: a familiar voice, convincing video or professional-looking message should not be treated as proof of identity.
Before transferring money or sharing sensitive details, customers should verify the request through a trusted, independent channel.
