SHAH ALAM - A viral video exposing a suspected Artificial Intelligence (AI)-powered scam has reignited global concerns over digital deception, after Northern Irish cybersecurity YouTuber Jim Browning outsmarted a deepfake impersonator during a live call by requesting a simple hand gesture.
The incident quickly gained traction online, drawing millions of views within a day and sparking widespread alarm over the capabilities of AI-driven impersonation.
Browning said the encounter began as a typical “compromised account” scam, a common tactic used to trick victims into believing their financial accounts were at risk.
The situation escalated during the ongoing video call, as the scammer presented himself as a credible, middle-aged professional in what appeared to be a corporate office setting.
Despite the convincing visuals, Browning detected subtle irregularities. He pointed out visual inconsistencies, including unnatural facial blending and flickering around the jawline, classic indicators of real-time deepfake overlays.
Suspicious of the caller’s identity, Browning directly questioned whether the individual was using AI. To verify his suspicions, he made an unusual request: perform a “three-finger test” on camera.
The response raised immediate red flags as Browning noticed that the caller’s hand movements were stiff and unnaturally positioned, while parts of the image, particularly the hair and facial edges, flickered during the gesture.
The caller also avoided bringing his fingers close to his face, seemingly afraid it might distort the image.
The incident revealed a disturbing reality: realistic fake identities can now be generated live, complicating the ability to tell authentic videos from deepfake manipulations.
Cybersecurity professionals have reinforced Browning’s approach, suggesting that using random, simple actions, such as having a caller perform gestures on command, is an effective way to identify suspected AI impersonations.
