深度偽造技術的危害：人工智慧偽造技術如何欺騙投資者和CEO！

Earlier this year, a video began circulating on social media in India that appeared to show Sundararaman Ramamurthy, the chief executive of the Bombay Stock Exchange, giving advice to investors about which stocks to buy. The video promised viewers that they could earn large profits if they followed his recommendations. However, the video was not real. It was a deepfake, created using artificial intelligence to mimic Ramamurthy’s appearance and voice. He had never actually made those statements.

Ramamurthy explained that the video was widely available online, which meant that many people could have seen it and been tricked into making financial decisions based on false information. Whenever his team discovers a fake video like this, they quickly report it to the authorities and contact social media platforms such as Instagram to have the video removed. They also regularly warn the public not to trust videos that might be fake. Ramamurthy admitted that it is very difficult to know exactly how many people saw the video or if it caused anyone to lose money. He hopes that no one was harmed by believing something that was not true.

This problem is not limited to India. According to Karim Toubba, the chief executive of the American cybersecurity company LastPass, the number of deepfakes has increased by nearly 3,000 percent in the past two years. Toubba himself was targeted by a deepfake in 2024. One of his employees in Europe received a message and an audio recording from someone pretending to be Toubba, urgently asking for help. Fortunately, the employee was suspicious because the message came through WhatsApp, which is not an official communication channel for the company, and it was sent to his personal phone. He reported the incident to the cybersecurity team, and no damage was done.

Other companies have not been as fortunate. In 2024, the British engineering firm Arup was the victim of one of the most advanced deepfake attacks ever seen in the business world. An employee in Hong Kong received a message that seemed to come from the company’s chief financial officer in London, asking about a confidential transaction. The employee joined a video call with what appeared to be the CFO and other staff members. Based on the instructions given during the call, the employee transferred $25 million to five different bank accounts. It was only later discovered that everyone on the call, including the CFO, was a deepfake.

Experts say that deepfakes are becoming easier and cheaper to create. Matt Lovell, the CEO of the UK cybersecurity company CloudGuard, explained that it now takes only minutes to make a high-quality deepfake video or audio. A simple attack can cost between $500 and $1,000, while more complex attacks might cost up to $10,000. At the same time, new tools are being developed to detect deepfakes. Some software can analyze a person’s facial movements or even the way blood flows under their skin to determine if they are real or fake.

Despite these advances, companies are in a constant race to stay ahead of cybercriminals. Toubba from LastPass said that there is a competition between those who create new technologies and those who try to stop them. He is hopeful because more money is being invested in developing ways to detect and block deepfakes. However, Lovell from CloudGuard is less optimistic. He believes that the methods used by attackers are improving faster than the defenses.

Stephanie Hare, a technology researcher, pointed out that there is a shortage of cybersecurity professionals around the world. She said that more people need to join the fight against cybercrime. Companies are starting to realize how serious the threat is, especially now that even top executives are being targeted by deepfakes. As a result, business leaders are spending more time working with their security teams to protect their organizations.

In conclusion, the rise of deepfakes is a growing problem for businesses and individuals. It is important for everyone to be cautious about what they see and hear online. If something seems unusual or too good to be true, it is wise to double-check before taking any action.
