How a $12B Cybersecurity Firm Outsmarted a CEO Deepfake Attack?

The cybersecurity industry is seeing a growing wave of deepfake attacks, and now even top executives are finding themselves targeted. Wiz, a prominent cybersecurity startup valued at $12 billion, was the latest company to fend off an attempt. The hackers’ strategy was to trick employees into revealing credentials by using an audio deepfake of CEO Assaf Rappaport’s voice. However, this sophisticated ploy failed due to the team’s attention to small yet critical details.

The Anatomy of the Deepfake Attack on Wiz:

Earlier this month, Wiz CEO Assaf Rappaport disclosed that hackers had created a fake audio message mimicking his voice. They used this clip in an attempt to deceive his employees into providing sensitive information. The attack involved sending the deepfake audio to dozens of Wiz team members, with the goal of gaining login credentials that could open doors to Wiz’s secure systems and, potentially, its troves of valuable data.

Unlike previous deepfake incidents that often go undetected, Wiz employees identified the audio as fake. According to Rappaport, the message sounded convincing to an untrained ear, but his team quickly recognized a mismatch. The voice in the message was based on Rappaport’s tone and cadence during a public speech—a setting in which he speaks differently than in daily interactions with his team. This subtle but crucial inconsistency raised enough suspicion to prevent the breach.

Why the Attack Failed: Small Details Matter

Wiz’s CEO noted a few specific factors that ultimately helped his team distinguish the deepfake. Rappaport mentioned that he often experiences public speaking anxiety, causing his voice and delivery to change slightly in formal settings. By drawing on their familiarity with how he speaks in day-to-day interactions, Wiz employees realized the message did not align with Rappaport’s typical communication style. This quick recognition of the discrepancy prevented a potential leak.

“That’s how they were able to say, ‘That doesn’t sound like Assaf,'” Rappaport shared at TechCrunch Disrupt. Such awareness among his team members served as an inadvertent line of defense against a highly realistic yet flawed deepfake.

Growing Threat of Deepfake Scams at Executive Levels:

Deepfake technology has grown alarmingly advanced, now posing risks to the highest levels of companies. In fact, recent incidents, such as one involving the world’s largest advertising firm WPP, showcase the lengths attackers are willing to go. In WPP’s case, hackers coordinated a Microsoft Teams meeting with a deepfake video and audio of the CEO, attempting to solicit money and personal information. While WPP detected and stopped the attempt, these cases underscore the urgent need for businesses to stay ahead of such threats.

According to a recent survey by cybersecurity firm Regula, deepfake attacks in 2024 have impacted about 50% of global businesses, with 66% of leaders citing it as a severe risk to their operations. As deepfake technology becomes increasingly accessible, companies must implement proactive measures, from employee training to advanced verification systems, to prevent these attacks from succeeding.

Lessons for Businesses: Strengthening Deepfake Defenses

Wiz’s experience offers several lessons for companies facing the ever-present risk of deepfake scams:

1. 1. Employee Training and Familiarity: Wiz’s staff successfully recognized the fake because they knew how their CEO usually speaks. Regular interaction with executives or training on their unique speaking style could help employees detect future impersonations.
2. 2. Enhanced Verification Protocols: As deepfakes become more convincing, relying on voice alone may no longer be enough. Verifying requests through additional methods, like video or security questions, can provide an extra layer of security.
3. 3. Awareness of Deepfake Risks: Educating teams on the existence and risks of deepfakes is essential. Companies should conduct workshops or simulations to help employees understand the signs of deepfake scams and know how to respond.
4. 4. Investing in Detection Tools: While it’s essential to train employees, AI-driven deepfake detection tools can also help flag potential threats in real-time. Some tech firms already offer software that can recognize subtle inconsistencies in synthetic media.

A New Era of Cybersecurity:

As AI and deepfake technology evolve, so do the tactics of cybercriminals. Wiz’s close call serves as a wake-up call for companies to stay vigilant and prepare for a world where cyberattacks involve AI-generated impersonations. While deepfake technology presents enormous potential in fields like entertainment and education, it also opens new doors for criminal exploitation. Cybersecurity companies and industry leaders are called upon to stay ahead, innovating with tools and protocols that detect and block these scams.

Conclusion:

The deepfake attack on Wiz reflects a new chapter in cybersecurity challenges. As this technology advances, businesses must adapt, training employees to recognize subtle indicators of fraud and investing in detection tools that can reveal deepfake manipulations. By staying informed and proactive, companies can strengthen their defenses against these deceptive and damaging attacks. For Wiz, the outcome was a victory—a testament to the effectiveness of employee awareness and the importance of small details in cybersecurity’s new frontier.
