AI换脸骗走2亿港币！专家支招：做这个动作
世纪君约 6 分钟A finance worker at a multinational firm was tricked into paying out HK$200 million ($25 million) to fraudsters using deepfake technology to pose as the company’s chief financial officer in a video conference call, according to Hong Kong police.
The elaborate scam saw the worker duped into attending a video call with what he thought were several other members of staff, but all of whom were in fact deepfake recreations, Hong Kong police said at a briefing.
“(In the) multi-person video conference, it turns out that everyone [he saw] was fake,” senior superintendent Baron Chan Shun-ching said.
Chan said the worker had grown suspicious after he received a message that was purportedly from the company’s UK-based chief financial officer. Initially, the worker suspected it was a phishing email, as it talked of the need for a secret transaction to be carried out.
However, the worker put aside his early doubts after the video call because other people in attendance had looked and sounded just like colleagues he recognized, Chan said.
据香港警方介绍，诈骗分子是利用了人工智能的深度伪造（deepfake）技术，从国外视频平台上下载了视频，模仿了公司高层人员的声音再对受害者发出行动指示，最终成功行骗。
由于AI形象在讲话时被人打断或提问容易漏出破绽，在视频过程中，嫌疑人曾要求受害者做简短的自我介绍，随后便没有其他口头互动交流，在用借口完结了对话之后，嫌疑人将沟通转移到线上即时通讯软件上进行。
1. 可以要求对方在视频通话时，在脸部前挥手，挥手过程会造成面部数据干扰，伪造的面部就会出现抖动等异常情况；
During a video call, have the other party wave their hand in front of their face. The motion can disrupt the artificial facial data, causing the fake image to exhibit glitches or shakiness.
Engage in conversation by asking questions that only the real person would be able to answer, thus confirming the identity of the individual you're speaking with.
For dubious identities, especially when someone claims to be a leader or an acquaintance, don't hesitate to double-check. A simple phone call or a quick check with mutual contacts can go a long way in confirming if the person is who they claim to be.
他在一个采访中表示，如果是真人的鼻子，按下去是会变形的，但AI生成的鼻子并不会。
Yuneng Hai, a leading figure in cybersecurity education, also recommends an additional measure: get them to press their nose or cheek. "When a real person does this, their nose will naturally squish and change shape," he notes in an interview. "An AI-generated face, on the other hand, won't show such natural deformations."
