There was a time when we could trust what we saw and heard. Today, that certainty has been shaken. The rapid advancement of generative artificial intelligence (GenAI) has pushed audio and video deepfakes to a level where creating a convincing fake clip takes only seconds — and the implications are deeply concerning.
Cybersecurity experts warn that no one is beyond reach. Deepfakes enable fraudsters to impersonate real individuals, whether to open bank accounts or deceive businesses. The most serious threat, however, lies in financial fraud, particularly in banking scams and unauthorized access to executives’ accounts.
Despite the growing scale of the problem, many organizations continue to underestimate the risk. Reports indicate a dramatic surge in synthetic video content within just a year, with actual figures likely even higher.
How attacks are carried out
Deepfake attacks — especially those involving audio — have never been easier to execute. All that is required is a short voice sample of the target, which can often be found in public appearances, interviews, or social media posts.
Attackers typically choose to impersonate someone in a position of authority, such as a CEO or CFO, and then identify a target within the organization, often through professional networking platforms. The approach may begin with an email or phone call, usually involving urgent requests such as transferring funds or resetting passwords.
With advanced speech-to-speech technology, attackers can even transform their voice in near real time to match that of the person they are impersonating, making the deception even more convincing.
Don’t always trust your ears
Modern tools make these attacks more realistic than ever. They can simulate background noise, pauses, and even subtle speech imperfections, making the audio sound authentic. In phone conversations, signs of artificiality can be even harder to detect.
At the same time, attackers rely heavily on social engineering tactics, applying pressure for immediate action or insisting on confidentiality. When a request appears to come from a senior executive, the likelihood of compliance increases significantly.
How to spot the signs
Although the technology is improving, there are still clues that may reveal a synthetic voice:
- Unnatural speech rhythm
- Flat or limited emotional tone
- Irregular breathing or lack of natural pauses
- Slightly robotic sound (especially with less advanced tools)
- Background noise that is either strangely absent or overly consistent
Defending Against the Threat
The financial incentives for attackers are substantial, which explains the rise in such incidents. In one notable case, an employee was tricked into transferring tens of millions of dollars after believing they were following instructions from a senior executive.
Addressing the threat requires a multi-layered approach:
- Employee training: Awareness of deepfake techniques and simulated attack exercises
- Clear procedures: Dual verification for major transactions and use of secure communication channels
- Verification methods: Pre-agreed passphrases or identity-check questions
- Technological solutions: Tools for detecting synthetic audio and limiting public exposure of voice data
A new threat landscape
The conclusion is clear: deepfakes are easy to produce and highly profitable for fraudsters. As the technology continues to evolve, organizations must remain vigilant.
Effective protection rests on three pillars — people, processes, and technology. Only through continuous adaptation can the risks of modern cyber fraud be mitigated.
