When Your Boss Isn’t Your Boss: The Rise of Deepfake Fraud

Picture this: you are in the middle of a busy workday when your phone rings. On the other end is your company’s CFO. The voice is unmistakable, calm, confident, and authoritative. They ask you to urgently transfer funds to close an overseas deal. You act quickly. Only later do you discover it was not your CFO at all. It was a deepfake voice, generated from less than a minute of audio scraped off the internet. The money is gone, and so is your trust.
Welcome to 2025, where accountants, finance professionals, and business leaders face a threat unlike any we have known before: AI-driven fraud and deepfakes.
A Fraud Tsunami Fueled by AI
The numbers are sobering. According to the World Economic Forum, deepfake fraud surged 1,740% in North America between 2022 and 2023, with global cases rising more than tenfold. By early 2025, losses already exceeded 200 million US dollars in a single quarter. One Hong Kong company was tricked into transferring 25 million US dollars after fraudsters used a synthetic CFO to authorise payments. In the UK, a British executive lost 20 million pounds in a similar scam.
Closer to home, these threats are not abstract. South African firms are increasingly being targeted with AI-enhanced scams: fake invoices, false bank instructions, and “urgent” payment requests backed up by cloned voices or even video calls. Research shows that 49% of companies globally encountered an audio or video deepfake in 2024, with average losses of nearly 8.5 million rand per incident.
And it is not just corporates. A McAfee survey found that 26% of individuals encountered a deepfake scam in 2024, and 9% admitted to being duped.
Why This Matters for Accountants
For accountants, trust is currency. The profession thrives on accurate reporting, verification, and independence. Deepfakes are designed to erode trust at its core, in documents, in people, and even in the voices of leaders.
Here are three ways this threat collides with our professional world:
Payment Authorisations – Fraudulent “CFO calls” or doctored invoices risk bypassing standard controls. Without careful verification, a simple voice message can cost millions.
Working Paper Evidence – When video recordings or digital confirmations can be faked, how do we establish reliability? The concept of “appropriate working paper evidence” is being redefined.
Reputation and Ethics – Beyond finance, 99% of non-consensual deepfake content targets women and girls, with devastating reputational consequences. Clients may seek professional guidance on crisis management, compliance, or legal recourse.
Fighting Fire with Fire
Fortunately, the world is responding. The United States has passed the TAKE IT DOWN Act, requiring platforms to remove non-consensual intimate deepfakes. Regulators in the EU and Asia are exploring mandatory watermarking of AI-generated content. In India, a Deepfake Analysis Unit now monitors election material.
Technology is also catching up. WaveVerify, a new audio watermarking tool, detects fake voices. India’s Vastav.AI claims 99% accuracy in spotting manipulated videos. Yet, experts caution that detection tools are always a step behind the fraudsters.
For accountants, the message is clear: internal controls, verification, and professional scepticism must adapt. Voice authentication, multi-factor approvals, and cross-channel verification of payment requests are now essential.
The Role of CIBA Members
As a CIBA member, you are not only a custodian of financial integrity. You are also a trusted advisor to businesses navigating risk. This creates both responsibility and opportunity.
Educate clients: Many SMEs are unaware of the scale of AI-driven fraud. Proactively raise awareness.
Review controls: Encourage clients to strengthen payment authorisations and segregation of duties.
Offer compliance services: Deepfakes touch on privacy, cybersecurity, and governance, all areas where accountants can add value.
Lead with ethics: In an environment where seeing is no longer believing, the accountant’s role in upholding truth becomes more critical than ever.
Conclusion: Trust, Reimagined
The rise of AI fraud and deepfakes is not just another cyber risk. It is a profound shift in how humans interpret reality, transact, and trust one another. For accountants, it challenges the foundations of verification and evidence. But it also reinforces why our profession matters.
As illusion becomes harder to spot, the real value lies in professionals who can cut through the noise, uphold ethical standards, and guide businesses safely through uncertainty. Deepfakes may clone faces and voices, but they cannot replicate integrity.
