「YouTube」に著名ちょめい投資とうし家かの音声おんせい合成ごうせいした偽にせ広告こうこく 詐欺さぎの新しん手口てぐちか

It has been found that there have been a series of cases on YouTube where fake video ads, using audio that appears to have been generated by AI to impersonate famous investors, are being displayed.

It appears to be a new method of scam advertising, and impersonated investors and others are warning people to be cautious.

Since the beginning of this month, there have been numerous reports on social media and other platforms about fake video ads impersonating famous investors being displayed on the video sharing site YouTube.

Of these, a female investor with over 630,000 YouTube subscribers has reportedly received more than 100 inquiries via email and comments from people who saw the fake advertisements.

In the fake advertisements, AI-generated audio is apparently combined with footage of the person, claiming things like I will personally share my investment know-how, and leading people to join a LINE group.

Fake video ads that use synthesized voices of famous investors have also been confirmed in several other cases, and they are considered to be a new method of scam ads aimed at defrauding people of money.

The frugal investor Fuyuko, who was impersonated, said, I dont do anything on LINE, and I dont run any ads on social media or YouTube.

Frankly, I cant forgive this, and I feel bad that my face was used without my permission.

I want platform operators to take proper measures so that no one falls victim to fraud, they said.

Google, which operates YouTube, clearly prohibits impersonation of celebrities.

We continuously review advertisements and take immediate action to remove any problematic ads detected, they commented.

Experts: “Strengthen systems for pre-screening and removal.” Until now, fake ads impersonating celebrities and investors have mainly appeared on social media platforms such as Facebook and Instagram.

Associate Professor Eijiro Mizutani of Keio Universitys Institute for Media and Communications, who is well-versed in issues related to online advertising, points out that the misuse of AI is making impersonation ads more sophisticated, and that platform operators need to further strengthen their systems for pre-screening and removal.

On top of that, Associate Professor Mizutani said, Platform operators have a considerable responsibility, and unless they further strengthen their countermeasures, it will be impossible to prevent fraud damage.

The operator said, It is necessary to work in cooperation, such as sharing the latest information with law enforcement agencies both in Japan and abroad.

Associate Professor Mizutani also said, With the spread of generative AI, many people are now able to use deepfake techniques, and there is a risk that in the future, it will become impossible to spot fake advertisements just by their appearance.

I think its also necessary not to easily click on or believe ads even if you see influencers or celebrities you know in them, they said.
