Whaling attacks have entered a new era. Once limited to fraudulent emails posing as urgent requests from executives, cybercriminals now leverage generative AI to exploit voice, likeness, and digital identity. Cases of AI-powered fraud utilizing executive impersonation are actively draining corporate accounts, exposing confidential data, and destroying brand integrity. To protect executives, company defenses must evolve at an unprecedented speed to keep pace with the advancement of AI attacks.

The Three Pillars of Modern Whaling Attacks

Today’s most effective whaling tactics exploit three primary attack vectors:

Vishing (Voice Phishing): AI-generated deepfake voices convincingly mimic executives, tricking employees into transferring funds or revealing sensitive data.

Video Conferencing Exploits: Deepfake video injects fake participants into meetings, enabling fraudsters to pose as trusted executives and enforce fraudulent requests.

Executive Brand Manipulation: Attackers use AI-generated caontent to impersonate corporate leaders on public-facing platforms, launching disinformation campaigns or engaging in financial fraud.

Whaling Through Vishing

Criminals can now clone an executive’s voice with flawless accuracy using readily available tools that require no technical know-how from users. Research from Truecaller reveals that voice-based fraud results in $25 billion in annual losses, while Regula reports that 37% of organizations worldwide have already fallen victim to voice deepfake scams. 

Vishing attacks prey on human psychology and workplace expectations. A well-trained employee might question an email request for funds, but when the voice on the line sounds exactly like their CFO’s, the decision to comply feels natural. This is why traditional anti-phishing training falls short against AI-driven fraud.

Executives are also prime targets for manipulation via phishing. Attackers don’t just impersonate leadership to deceive employees — they create deepfake versions of legal advisors or regulators to manufacture a sense of urgency and manipulate executives into high-risk actions impacting companies at the highest levels. 

What CISOs Can Do to Mitigate This Threat:

Implement secondary verification protocols. Every financial request should require a secondary confirmation via a different communication channel.

Adopt AI-driven voice authentication. Deepfake detection technology can flag manipulated audio before damage occurs.

Train staff on AI-driven fraud risks. Educating employees on deepfake threats is now just as critical as phishing awareness.

Video Conference Infiltration

The era of implicitly trusting video conferencing is over. Cybercriminals are weaponizing advanced generative AI to create hyper-realistic deepfake videos that impersonate team members, particularly executives, infiltrating meetings and deceiving even seasoned colleagues. 

Research from Tenable reveals that 74% of organizations suffer security breaches tied to remote work tools, with video conferencing as a primary attack vector. High-stakes whaling incidents are making the headlines: Arup lost a staggering $25 million in 2024 to a single deepfake video conference scam. Even a U.S. Senator fell victim to a virtual meeting with a fake Ukrainian official. 

The consequences are far-reaching, as malicious actors can exploit video deepfakes beyond financial fraud to conduct corporate and government espionage. Impersonating company and government leaders during conferences, they can sway negotiations, expose confidential data, and manipulate strategic decisions.

What CISOs Can Do to Mitigate This Threat:

Establish pre-meeting authentication protocols. Before discussing sensitive information, participants can confirm identities through pre-shared verification steps.

Deploy real-time deepfake detection. AI-powered analysis can detect manipulation in video feeds, preventing fraudulent participation.

Create escalation pathways. If something feels “off” in a video meeting, employees should have a direct channel to verify identities without hesitation.

Weaponizing Digital Presence

Executives cultivate strong digital footprints — LinkedIn posts, TV appearances, podcasts. While these communications build credibility and brand voice, they also provide attackers with everything they need to craft hyper-personalized whaling attacks.

Attackers refine their approaches through reputation leveraging, studying an executive's online presence and communication style to craft convincing impersonations. Attackers can use these forgeries to create and disseminate audio clips and videos of executives making false statements about company performance, product failures, or regulatory issues. Fabricated communications can seriously affect brand reputation and trigger rapid stock price volatility.

Cross-channel validation — where attacks simultaneously appear across multiple social platforms — is an increasingly concerning tactic. A LinkedIn post might reference a deepfake video on X, creating an illusion of legitimacy. When the public encounters consistent messaging from company leadership across different channels, they are more likely to believe it.

What CISOs Can Do to Mitigate This Threat:

Continuous monitoring of executive digital footprints. Detect impersonation attempts before they spread with narrative intelligence.

Deploy AI-driven brand protection tools. Leveraging detection across communication channels can flag fake content before it reaches employees or the public.

Develop response plans for executive deepfake incidents. Having a crisis playbook in place can mitigate reputational damage if a whaling attack occurs.
