Understanding Deepfake Video Call Scams: Protect Yourself from AI Fraud
Deepfake Video Call Scam 2026
Artificial intelligence is revolutionizing the tactics used by cybercriminals. Scammers are now capable of utilizing AI-generated images and replicated voices to impersonate trusted individuals such as family members, friends, or business leaders during video calls.
Unlike conventional phone scams, these video calls can seem highly credible since the individual on the screen appears familiar. Criminals take advantage of this trust to solicit urgent payments, gather sensitive information, or authorize fraudulent transactions.
However, the presence of a realistic face or recognizable voice in a video call is no longer a reliable indicator of someone's identity.
What Is a Deepfake Video Call Scam?
A deepfake video call scam employs artificial intelligence to replicate a person's appearance, voice, or both.
Scammers can create convincing impersonations using images, videos, or audio clips sourced from public domains or other means.
For instance, an individual might receive a video call that seems to show a relative requesting money after an accident.
In another scenario, an employee could receive a video meeting invite from someone posing as a senior executive asking for an urgent fund transfer.
The success of these scams often hinges on three elements: familiarity, urgency, and pressure to act without verification.
Hong Kong Deepfake Fraud: A Major Warning
A notable incident involving the engineering firm Arup highlighted how advanced AI impersonation can facilitate financial fraud.
As reported, an employee in Hong Kong participated in a video meeting where several attendees appeared to be company executives and colleagues.
These participants were allegedly impersonated using deepfake technology.
Believing the instructions were legitimate, the employee transferred around HK$200 million (approximately US$25.6 million) across 15 transactions.
This case underscores the importance of adhering to established payment approval protocols, even during video conferences with familiar faces.
Five Possible Warning Signs of a Deepfake Video Call
Some manipulated videos may exhibit unusual visual or audio features, but these signs alone do not confirm fraud.
1. Unusual Eye Movements
A person may blink unnaturally, maintain a fixed gaze, or display inconsistent eye movements.
However, genuine video calls can also show unusual movements due to camera quality, lighting, or connectivity issues.
2. Lip Movements That Do Not Match Speech
A discrepancy between spoken words and lip movements can raise suspicion.
Yet, audio delays are common in regular video calls, especially with unstable internet connections.
This sign should not be the sole basis for determining if a video is fake.
3. Unnatural Facial Expressions
AI-generated faces may display inconsistent expressions or overly smooth skin.
However, modern video filters, compression, and lighting can create similar effects in authentic calls.
4. Distortion Around the Face
Blurred edges around the hair, ears, jawline, or glasses may indicate video manipulation.
Such distortions can become more apparent when a person moves.
Nonetheless, typical video-processing issues can produce similar visual artifacts.
5. Inconsistent Lighting or Background
Unexpected changes in facial lighting, shadows, or background movement may warrant scrutiny.
These irregularities are potential warning signs but do not provide reliable confirmation of a deepfake.
Important: A fraudulent video call may not exhibit any of these abnormalities. The absence of visible errors does not guarantee authenticity.
How to Verify a Suspicious Video Call
If a caller requests money, confidential information, or unusual actions, verification is crucial, regardless of any technical flaws.
Ask an unexpected question: A question based on a recent private conversation may help reveal an impersonator. However, criminals may already have personal information, so the answer should not be considered definitive proof.
Request a change in movement: Asking the caller to turn their head or move a hand across their face may expose visual inconsistencies in some manipulated videos. More advanced deepfakes may convincingly handle these movements.
Check the context: An unexpected request for an urgent transfer, secrecy, or a change in payment details should raise concerns, regardless of how realistic the caller appears.
End the call and contact the person independently: This is the most critical precaution. Use a phone number or communication channel that you know is genuine, rather than the contact information provided during the suspicious call.
Do not authorize any payment until the request has been independently verified.
Can AI Clone Someone's Voice?
Yes, AI voice-cloning tools can replicate speech patterns, tone, and pronunciation.
While some cloned voices may sound robotic or have unusual pauses, advanced systems can produce highly realistic speech.
Thus, recognizing someone's voice is not sufficient evidence that the caller is genuine.
If a familiar person unexpectedly requests money or confidential information, confirm the request through a separate trusted channel.
Why Urgent Money Requests Are a Major Warning Sign
Deepfake scams often exploit emotional pressure.
A caller might claim that a family member has been hospitalized, that a business payment must be completed immediately, or that a confidential transaction requires urgent approval.
Fraudsters may also discourage victims from contacting anyone else.
These tactics are designed to hinder careful verification.
While genuine emergencies can also involve urgency, the request itself does not confirm fraud. Nevertheless, the need for immediate action makes independent confirmation particularly vital.
Can a Family Codeword Help Prevent Deepfake Fraud?
Families might consider establishing a private codeword for unexpected emergency requests.
If someone claims to be a relative and asks for urgent financial help, the codeword could serve as an additional verification step.
However, codewords can be disclosed, guessed, or obtained through compromised communications.
They should be viewed as a supplementary safeguard rather than a replacement for contacting the person through a trusted number.
What Should You Do If You Have Already Sent Money?
If you suspect that a deepfake video call has led to financial fraud, act swiftly.
- Contact your bank immediately. Use its official customer support number to report the suspicious transaction.
- Call the national cybercrime helpline at 1930. Provide the relevant payment details.
- Submit a complaint through the official portal: https://cybercrime.gov.in.
- Preserve evidence. Keep transaction IDs, payment receipts, phone numbers, messages, and available screenshots.
- Secure affected accounts. If passwords, OTPs, or other sensitive information were disclosed, follow the relevant bank or service provider's security instructions.
Prompt reporting may enhance the chances of tracing or restricting fraudulent transfers, although recovery of the funds is not guaranteed.
How Can Businesses Prevent Deepfake Payment Fraud?
Companies are also at risk of impersonation attacks targeting senior executives and finance teams.
Organizations can mitigate this risk by requiring independent confirmation of unusual payment instructions.
For instance, a significant transfer requested during a video meeting should still adhere to the company's established approval process.
Additional safeguards may include dual authorization, verification through previously registered contact details, and employee training on AI impersonation.
A convincing video meeting should never replace financial controls.
Simple Precautions Against AI Video Call Scams
- Avoid trusting unexpected financial requests solely based on the caller's appearance.
- Never disclose OTPs, passwords, UPI PINs, or banking credentials during suspicious calls.
- Verify unusual requests through a previously established contact channel.
- Be cautious about sharing personal videos and voice recordings publicly.
- Keep your phone and communication applications updated.
- Educate family members about AI impersonation scams.
While these measures cannot eliminate every cyber threat, they can significantly reduce the likelihood of falling victim to impersonation-based fraud.
Can Every Deepfake Video Be Identified by Looking Closely?
No, AI-generated video and audio are becoming increasingly sophisticated.
Visual cues such as unnatural blinking, mismatched lips, or distorted facial edges may sometimes indicate manipulation, but they are not reliable detection methods.
Similarly, an authentic video call may exhibit temporary glitches due to poor connectivity or camera processing.
The safest approach is to verify the caller's identity independently before transferring money, sharing sensitive information, or approving an unusual request.
Conclusion
Deepfake video call scams illustrate how artificial intelligence can be misused to impersonate trusted individuals and manipulate financial decisions.
While unusual facial movements, audio delays, and inconsistent lighting may raise suspicion, these signs cannot reliably differentiate genuine calls from AI-generated impersonations.
The most effective precaution is to pause and verify unexpected requests through a trusted communication channel.
If financial fraud occurs, contact your bank immediately and report the incident through the national cybercrime helpline 1930 or the official portal cybercrime.gov.in.
