Understanding Voice Generation AI and Vishing Threats

Vishing, or voice-based phishing, has evolved from crude robocalls to sophisticated scams powered by voice generation AI and deepfake technology. These advancements have made vishing a significant threat to businesses and individuals alike.

The stakes are high: vishing costs businesses over $14 million annually, and attackers achieve a 77% success rate, resulting in stolen credentials, data breaches, and financial losses.

In this blog, we’ll uncover how AI fuels vishing attacks, the challenges this creates, and strategies to combat these growing threats.

What Is Vishing?

Vishing involves fraudulent phone calls or voice messages designed to trick victims into revealing sensitive information or performing harmful actions. Cybercriminals often impersonate trusted figures, such as executives or bank representatives, to gain credibility and exploit human trust. These scams rely heavily on social engineering tactics to manipulate their victims.

Deepfakes: The Game-Changer in Vishing

Deepfakes use AI to generate realistic voices or videos that convincingly mimic real individuals. This technology has turned vishing from basic scams into highly sophisticated attacks that are nearly impossible to detect. For example, attackers can convincingly replicate a CEO’s voice to authorize fraudulent transactions or extract confidential data. As deepfake technology becomes more accessible, such scenarios are becoming increasingly common and dangerous.

The Growing Wave of Vishing Attacks

Vishing attacks have surged in recent years. According to the Quarterly Threat Trends & Intelligence Report by Agari and PhishLabs, vishing incidents increased by 550% in 2022, with businesses and financial institutions being primary targets. A notable example of the risks posed by AI-generated voices occurred when a journalist successfully bypassed a bank’s voice authentication system using an AI-generated voice, exposing critical vulnerabilities in voice ID technologies.

Case Study: The Joe Rogan Deepfake

A vivid example of deepfake misuse occurred in early 2023, when a TikTok ad featured podcast host Joe Rogan seemingly endorsing a male enhancement supplement called Alpha Grind. The ad, created using AI-generated voice and imagery, was entirely fake and published without Rogan’s consent. This misleading video gained millions of views before being removed, illustrating how deepfakes can damage reputations, deceive consumers, and spread misinformation. The incident underscores the urgent need for businesses to implement safeguards against such AI-driven threats.

Vishing-as-a-Service: A Growing Threat

Cybercriminals are increasingly turning to vishing-as-a-service, using AI-powered platforms to automate and scale voice phishing campaigns. While these platforms often have legitimate applications, their misuse has fueled the rise of professionalized cybercrime, making vishing attacks more prevalent and sophisticated.

Challenges in Detecting and Preventing Vishing

AI-generated voices are highly realistic, rendering traditional detection methods ineffective. Many voice authentication systems are now vulnerable, requiring organizations to adopt more advanced tools like biometric analysis and voice pattern recognition to combat these threats.

Best Practices to Defend Against Vishing

• Strengthen Multi-Factor Authentication (MFA): Combine voice authentication with additional layers, like SMS codes or app-based approvals, to enhance security.
• Adopt Advanced Biometric Tools: Use technologies that analyze voice cadence and patterns to detect and block AI-generated fraud attempts.
• Educate Employees: Implement security awareness training to help employees recognize vishing scams, verify unusual requests, and avoid falling victim to social engineering tactics.

Keepnet Human Risk Management Platform

The rise of voice generation AI has made vishing attacks harder to detect and prevent. Organizations need practical solutions to strengthen their defenses and minimize risks. Keepnet’s tools are tailored to address these challenges:

• Vishing Simulator: Train employees to identify and respond to voice phishing attacks with realistic, controlled simulations. These exercises replicate advanced scams, improving employee vigilance and decision-making under pressure.
• Security Awareness Training: Build a cyber-aware workforce with tailored training programs that prepare employees to spot and respond effectively to vishing and other social engineering threats.

Together, these solutions empower organizations to stay ahead of evolving vishing threats and safeguard their most valuable assets.
