Voice phishing, or vishing, is one of the fastest-growing cyber threats in 2026. According to CrowdStrike, the number of vishing attacks rose by 442% in the second half of 2024, and that trend is continuing.
AI-generated voices
With generative AI, attackers can now clone voices based on just a few seconds of audio. This makes it possible to convincingly impersonate a colleague, manager, or IT employee.
Deepfake video calls
In addition to voice cloning, we are seeing an increase in deepfake video, where attackers visually impersonate well-known people within the organisation.
Automated social engineering
AI tools make it possible to carry out highly personalised attacks at scale, tailored to the specific context of each target.
What does this mean for your organisation?
The only way to know how your organisation responds to these threats is to test it. DeepCalls conducts realistic voice phishing assessments that show exactly where the vulnerabilities lie.
