In a recent investigation, Hong Kong's underground market is selling advanced deepfake software capable of altering faces and voices with startling realism. Criminals use this technology to commit identity theft and ransom scams. For just USD 3,000 (approximately HKD 23,000) annually, this software is being marketed as an all-in-one solution for creating high-quality fake videos.
Mr. Zhao, a Mainland China resident, recently experienced a deepfake scam involving his son studying in Hong Kong. In October last year, he received a video call showing his son kneeling and pleading for help. The "kidnappers" demanded a HKD 6 million ransom.
The highly convincing video was created using deepfake technology. The scammers had earlier deceived Zhao's son into isolating himself and handing over access to his phone, under the pretense of being part of a confidential police investigation. Using data from his son's video calls, the scammers generated the fake video to extort the family.
Fortunately, Zhao's friends intervened and contacted the police. Authorities located Zhao's son unharmed in Sai Kung, revealing the scam.
A reporter from Wen Wei Po infiltrated a secret Telegram group where deepfake technology is openly advertised. The seller, claiming to be an "AI expert," demonstrated the software's capabilities, including recreating faces, mimicking movements, and seamlessly switching facial features.
The software is marketed with bold promises such as:
"Unparalleled realism", "Perfect facial swaps with no errors", "Full support for video calls and virtual backgrounds"
The seller emphasized that the software could construct an eerily lifelike deepfake video with just one photo. The technology is already being used for scams, including impersonating celebrities or family members to endorse fake investments or extort money.
How to detect deepfake scams
To combat deepfake scams, experts and authorities recommend the following measures to verify the authenticity of a video or video call:
- Cover the face: Ask the caller to cover their face with their hand to reveal any inconsistencies.
- Move the camera: Request the caller to move the camera to capture other people or surroundings.
- Observe facial details: Look for unnatural features, such as mismatched skin tones or overly smooth textures.
- Pay attention to body movements: Check if the body or background remains unnaturally static.
- Ask personal questions: Verify the caller's identity by asking questions only they would know.
The rapid advancement of AI technology has made it increasingly difficult to distinguish deepfake content from real videos. Criminals are exploiting this to target unsuspecting victims, leading to devastating financial and emotional consequences. Authorities in Hong Kong urge citizens to remain vigilant and report any suspicious activities or scams to the police.
