“The call looks real. The voice sounds familiar. But the person on the other end isn’t who you think.”

In today’s connected world, cybercriminals can easily impersonate individuals, including bank managers or family members. With personal data stored online, tracing these threats has become increasingly complex. By 2025, scammers are expected to have advanced to using AI-powered voice cloning and deepfake technology, making fraudulent calls increasingly challenging to detect.

Infosprint Technologies, a cybersecurity solutions provider, recognizes the threat posed by caller ID spoofing and has researched effective ways to protect yourself from these evolving attacks.. This blog examines the phenomenon of phone spoofing, its rise, and how to safeguard your data and maintain trust.

What Is Phone Spoofing?

Phone spoofing is a technique used by fraudsters to communicate with others by falsifying their caller ID information. Instead of displaying the caller’s real phone number, the spoofed number may appear as that of a reputable organization — such as a bank, government agency, or even someone you know, like a friend or relative.

The scammer’s objective is to fool you into taking the call and trusting the source, which can lead to the unintentional disclosure of personal data or the authorization of transactions.

How Does Phone Spoofing Work?

Cybercriminals disguise themselves to gain your trust by impersonating a legitimate source. Caller ID spoofing works by tampering with the technology that transmits caller ID data between phone networks. Scammers commonly use Voice over Internet Protocol (VoIP) services or specialized software to alter the number that appears on your phone’s caller ID.

In 2025, some attackers have taken this further, using AI voice synthesis to replicate the voices of real people, such as bank representatives or law enforcement officers. This makes spoofing attacks more convincing and dangerous, particularly in regions such as Canada and Singapore, where the banking and telecom sectors are heavily digitalized.

For instance, scammers may impersonate police officers and claim that you have committed fraud by simply stating your name and mobile number. This strategy compromises your judgment and pressures you to provide personal information, such as your address, email, Aadhaar number, or family details. Once they have this data, they may instruct you to install malicious apps that secretly access your device and financial data.

Spoofing 101: Different Ways Cyber Attackers Disguise Themselves

According to recent cybersecurity reports, over 60% of mobile users receive at least three spam or spoofed calls daily. Recognizing the type of spoofing attempt is crucial to staying safe.

Here are some of the ways scammers use caller ID spoofing:

• Neighbor Spoofing: Scammers use the same area code as their victims to create a sense of familiarity, increasing the chances that the call will be answered.
  
• Government Agency Spoofing: This technique aims to intimidate victims into providing personal details or making payments under the guise of law enforcement or tax agencies.
  
• Bank Spoofing: When a fraudster’s call appears as if it’s coming from your bank’s official number, urging you to share OTPs or verification details to “secure” your account.
  
• Customer Care Spoofing: Cybercriminals impersonate the support lines of trusted brands to collect account credentials and personal information.
  
• Voicemail Spoofing: Attackers leave pre-recorded voice messages urging victims to call back about an “urgent matter,” leading them into a scam.
  
• AI Voice Spoofing (New Trend): In 2025, scammers began using AI voice cloning to replicate real voices. The Canadian Anti-Fraud Centre (CAFC) reports a surge in cases where fraudsters mimicked bank representatives or family members to request verification codes or transfers.

The Dangers of Phone Spoofing in Online Banking and Financial Transactions

Phone spoofing poses a significant risk to online banking and financial transactions. With digital payments becoming the global norm, spoofing has evolved into one of the most effective tools for cybercriminals.

1. Fraudulent Account Access

Scammers impersonate bank staff, requesting OTPs or PINs under the pretext of verifying suspicious activity. Once obtained, they gain unauthorized access to accounts and conduct illicit transfers within seconds.

In early 2025, a Toronto resident fell victim to such a scam, losing over $200,000 after receiving calls from individuals impersonating RCMP officers and her bank’s fraud department. Despite showing legitimate caller IDs, the calls were spoofed through VoIP masking.

2. Identity Theft

Using caller ID spoofing, criminals collect personal data — names, dates of birth, banking details — to open fraudulent credit lines or apply for loans under stolen identities.

3. Phishing and Vishing Attacks

Phone spoofing amplifies traditional phishing. “Vishing” (voice phishing) occurs when scammers call pretending to be from trusted institutions. Victims are lured into visiting fake banking sites or disclosing sensitive credentials.

4. Social Engineering Scams

Spoofing supports larger social engineering attacks, where scammers impersonate advisors, managers, or law enforcement. Victims are manipulated into wiring money, investing in fake opportunities, or providing confidential security details.

5. Business Compromise

Corporate phone spoofing remains a global issue. Criminals spoof executives’ numbers to trick employees into transferring funds. These Business Communication Compromise (BCC) incidents mirror email-based BEC scams and are particularly prevalent across North America and Asia.

Real-Life Scenarios of Phone Spoofing

Recent incidents highlight the global scale of this threat:

• In Canada, multiple reports from 2024–25 indicate that spoofed RCMP and Service Canada calls have led to significant financial losses.

• In the U.S., scammers mimicked Chase Bank and Zelle representatives to steal one-time passcodes from users.
  
• In Singapore, AI voice spoofing was used to imitate bank agents from DBS in a coordinated phishing campaign.

These examples demonstrate that, despite regional differences, cybercriminals employ universal tactics — exploiting trust, urgency, and new technology.

How to Protect Yourself from Phone Spoofing

Knowing how to defend yourself is essential to avoid becoming a victim. Below are practical ways to secure personal and financial data from caller ID spoofing scams:

1. Be Wary of Unsolicited Calls:
   Even if the caller ID displays a trusted name, verify the identity before sharing any information. Hang up and call back using the organization’s official number.
   
2. Never Share Sensitive Data:
   Account numbers, passwords, and OTPs should only be given if you initiated the call and confirmed the source. Legitimate banks will never request these details over the phone.
   
3. Enable Multi-Factor Authentication (MFA):
   Even if your credentials are stolen, MFA prevents unauthorized access.
   
4. Use Verified Calling Features:
   In Canada and the U.S., carriers now use STIR/SHAKEN technology to verify caller authenticity. Look for “Verified Call” indicators on smartphones.
   
5. Use Call-Blocking Apps and Services:
   Several providers globally (Bell, Verizon, Singtel, Airtel) offer AI-powered call filters that identify suspected spoofed calls.
   
6. Report Suspicious Activity:
   
   • Canada: Report to the Canadian Anti-Fraud Centre (CAFC) or CRTC Spam Reporting Centre.
     
   • U.S.: Report to the FTC’s Do Not Call Registry.
     
   • Asia-Pacific: Utilize local cybersecurity helplines or support from your telecom provider.
     
7. Monitor Accounts Regularly:
   Set alerts for large withdrawals or unusual login activity to detect fraud early.
