KnowBe4 Launches Simulated Vishing Tool Amid Surge in Voice-Based Attacks
Event summary
- KnowBe4 introduced simulated vishing capabilities to combat rising voice-based threats, integrating them into its security platform.
- Vishing attacks surged 442% between the first and second halves of 2024, per CrowdStrike's 2025 Global Threat Report.
- Verizon's 2026 Data Breach Investigations Report found employees are 40% more likely to fall for phone-based simulations than email phishing.
- The new tool includes realistic caller ID, personas, and multi-step scenarios to mirror real-world vishing tactics.
The big picture
Vishing has evolved from a niche tactic to a mainstream attack vector, driven by AI voice cloning and high employee susceptibility. KnowBe4's move reflects the broader industry shift toward securing both human and AI agents against sophisticated social engineering threats. The tool's integration into existing reporting frameworks could set a new standard for measuring voice-based risk.
