What is Vishing?

Vishing (voice phishing) uses phone calls to deceive victims. With AI voice cloning, attackers can now make calls that sound exactly like someone the target knows and trusts—their CEO, CFO, or even family members.

Real Attack Example

In 2024, a finance employee at a multinational company transferred $25 million after attending a video call with what they believed were their CFO and colleagues. Every person on the call was a deepfake.

Types of Deepfake Attacks

Voice Cloning Calls

Phone calls impersonating executives to authorize wire transfers, share credentials, or divulge sensitive information.

Video Deepfakes

Real-time video manipulation on conference calls, creating convincing fake participants.

Audio Voicemails

Fake voicemails from "executives" requesting urgent action, especially effective outside business hours.

Impersonation Attacks

Combining deepfakes with breached personal data for highly convincing social engineering.

Defense Strategies

Establish verification code words for sensitive requests
Always verify financial requests through a separate channel
Train employees to recognize deepfake warning signs
Implement dual authorization for large transactions
Limit public audio/video of executives (attackers use this to train models)
Monitor for exposed personal data that could fuel attacks
The Data Connection
Deepfake attacks are more convincing when attackers know personal details about their targets. Exposed credentials and personal data from breaches give attackers the context they need to craft believable scenarios. Credential monitoring helps identify what attackers might know about your employees.
