Sophisticated tricks
“Deepfake” is a combination of “deep learning” and “fake”, which is a method of creating fake technology products in the form of audio, images or even videos, by sophisticated artificial intelligence (AI). Deepfake is a technology that creates audio, image and video technology products that fake real-life objects with very high accuracy. Based on the image file of a real-life person's face and voice, Deepfake will use algorithms to recreate the face and voice that match the facial features and expressions of another person, then create a fake video of the real-life object.
To commit fraud and appropriate property of social network users, first, the subject creates a fake social network account with the same information and profile picture as the user or takes over the user's social network, then collects personal information, images, videos with voice posted publicly on the social network account and then uses Deepfake technology to create animated images and fake videos of the user talking online with the same face, voice tone and form of address.
Or the subject creates a fake social network account with the same information and profile picture as the user, befriends the victim in the friend list and sends messages to borrow money according to a pre-existing scenario. In some cases, the subject hijacks the user's social network account to directly message the victim in the friend list. To gain the victim's trust, the subject uploads available Deepfake videos to the video call channel, making the victim recognize the image and voice of an acquaintance and transfer money according to the subject's request.
With Deepfake technology, fake videos have high accuracy, making it difficult to distinguish between real and fake. However, videos created by the subject often have general content, not completely consistent with the actual context of communication with the victim, which can make the victim suspicious and detect. To cover up the above shortcomings, the subjects often create videos with difficult to hear sound, unclear images, similar to video calls with unstable signals made in areas with weak mobile or wifi coverage.

When receiving any message or video call with an unstable or unclear signal to borrow money, you need to call directly to the recipient's phone number to verify, do not call via social networking applications such as Zalo, Messenger, Viber, Telegram... because these accounts may have been hijacked.
