South Africa’s top cryptocurrency platform, Luno, is on high alert following a recent AI-driven deepfake scam that targeted one of its employees. This incident underscores the rising threat of sophisticated digital fraud in the rapidly evolving cryptocurrency industry, as Luno intensifies its efforts to safeguard its operations and protect its users.

Recently, Luno narrowly avoided a major crisis when an employee received a deepfake audio message via WhatsApp, supposedly from a senior executive. Although the voice and instructions sounded convincing, they were ultimately flagged as suspicious, preventing any potential harm. This case underscores the increasing sophistication of these attacks.

In a world where artificial intelligence (AI) is advancing at an unprecedented rate, deepfakes—highly convincing synthetic media generated using AI—have emerged as a potent tool for cybercriminals. These fraudulent digital manipulations can mimic real voices, faces, and even entire personas with alarming accuracy, making it increasingly difficult for individuals and businesses to distinguish between what is real and what is fake.

Deepfakes, which are highly realistic synthetic media created using artificial intelligence, are being increasingly exploited by criminals to deceive both individuals and businesses. The financial losses from such scams can be enormous. For instance, in Hong Kong, an employee was tricked into transferring USD 26 million after being deceived by deepfakes of colleagues during a video call, including one impersonating the company’s chief financial officer.

Elon Musk, the tech billionaire, has also become a favorite target for fraudsters due to his high public profile. After SpaceX’s Starship launch, YouTube was inundated with deepfake videos of Musk falsely promoting lucrative returns on fake cryptocurrency investments. This illustrates how quickly and broadly these scams can spread.

Luno, which provides a platform for buying, storing, and learning about cryptocurrencies like Bitcoin and Ethereum to millions of users across 40 countries, is aware of the escalating threat posed by deepfakes. Given that Luno’s business involves handling digital assets, it is an attractive target for fraudsters.

Johan Hetzel, Luno’s global head of compliance and anti-financial crime, warns that deepfakes present a significant risk in the cryptocurrency sector. “Deep fakes are a substantial risk in the cryptocurrency sector,” he said. While traditional financial systems allow fraudsters to spread money across multiple institutions, the blockchain technology that underpins cryptocurrencies enables crypto service providers to track transactions beyond their immediate network. However, the psychological impact of deepfakes, which blurs the line between reality and fiction, remains a significant challenge.

Recognizing the seriousness of the situation, Luno has taken swift action to counter the rising threat of deepfake scams. The company has formed a specialized team dedicated to monitoring and identifying fraudulent activity across social media platforms and websites. Over the past year, this team has been instrumental in proactively detecting and taking down over 2,000 fake social media accounts and nearly 500 fraudulent websites that sought to exploit Luno’s brand. The company reports a takedown success rate of 98% for social media pages and 87.6% for websites.

“Fraud poses a significant challenge not only to cryptocurrency service providers but also to the broader financial services sector in South Africa,” explains Hetzel. Luno underscores the need for caution to safeguard its users, advising them that if something seems too good to be true, it likely is. The company advocates for users to confirm the legitimacy of any communications and to take their time when making decisions.

Luno’s recent experience is not just a cautionary tale for the cryptocurrency industry but for the broader financial services sector in South Africa. As deepfake technology becomes more accessible, the risk of such scams extends far beyond the crypto world. The ability of fraudsters to convincingly impersonate senior executives or other trusted individuals poses a serious threat to any organization that handles sensitive information or transactions.

Blockchain technology, which is central to the operation of cryptocurrencies, also holds promise in the fight against deepfakes. Its decentralized and secure nature can be leveraged to verify the authenticity of digital content, potentially making it a valuable tool in the battle against AI-driven fraud. For instance, non-fungible tokens (NFTs), which are recorded on the blockchain, can authenticate the creator and owner of digital content, making it harder for counterfeiters to succeed.

The incident at Luno serves as a stark reminder of the growing sophistication of digital fraud and the need for continuous vigilance. As AI technology continues to advance, the threat posed by deepfakes is likely to increase, requiring a concerted effort from the entire industry to stay ahead of the curve.

Luno’s proactive approach to combating deepfakes is commendable, but it is clear that the fight against this emerging threat is far from over. By staying vigilant and leveraging the strengths of blockchain technology, Luno and other companies can better protect themselves and their users from the ever-evolving landscape of digital fraud.
