The threat described involves the evolution of phishing attacks through the integration of advanced technologies such as deepfakes, vishing (voice phishing), and GPT-based scams. Deepfakes utilize AI-generated synthetic media to create highly realistic but fake audio or video content, which can be exploited to impersonate trusted individuals, such as executives or colleagues, to deceive victims. Vishing leverages phone calls or voice messages to manipulate targets into divulging sensitive information or performing actions that compromise security. GPT scams involve the use of advanced language models like OpenAI's GPT to generate convincing phishing messages, social engineering content, or fraudulent communications that are more difficult to detect due to their natural language fluency and contextual relevance. This combination significantly enhances the sophistication and effectiveness of phishing campaigns, making them more personalized, believable, and harder to identify using traditional detection methods. The threat does not target specific software versions or products but represents a broader trend in social engineering attacks that exploit AI technologies to increase success rates. Although no known exploits in the wild are reported, the rapid advancement and accessibility of these AI tools pose a growing risk to organizations worldwide.

For European organizations, this threat can lead to severe consequences including unauthorized access to sensitive data, financial fraud, intellectual property theft, and reputational damage. The use of deepfakes and GPT-generated content can bypass conventional security awareness training and automated email filtering systems, increasing the likelihood of successful compromise. Critical sectors such as finance, government, healthcare, and energy are particularly vulnerable due to the high value of their data and the potential for disruption. Additionally, the cross-border nature of these attacks complicates incident response and attribution, potentially leading to regulatory penalties under GDPR if personal data is compromised. The psychological impact on employees and stakeholders can also erode trust and operational efficiency. Given the medium severity rating and the evolving nature of these threats, European organizations must proactively adapt their defenses to address these AI-enhanced social engineering tactics.

Mitigation strategies should focus on enhancing detection, prevention, and response capabilities tailored to AI-driven phishing threats. Organizations should implement multi-factor authentication (MFA) universally to reduce the impact of credential compromise. Advanced email and voice communication filtering solutions that incorporate AI and machine learning can help detect anomalies indicative of deepfakes or GPT-generated content. Regular, scenario-based security awareness training should be updated to include examples of AI-enhanced phishing and vishing attacks, emphasizing verification protocols for unusual requests, especially those involving financial transactions or sensitive data access. Establishing strict verification procedures for requests received via phone or video calls, such as callback policies using known numbers, can mitigate vishing risks. Incident response plans must be revised to include procedures for handling AI-based social engineering incidents. Collaboration with law enforcement and sharing threat intelligence within industry sectors can improve detection and prevention efforts. Finally, investing in emerging technologies that can detect deepfake media and synthetic content will provide an additional layer of defense.
