The company found malicious impersonations via Teams surged 502% year-on-year, while over 46 million business contact impersonation attacks occurred in the last 12 months. AI is now used to generate realistic voice clones, alter accents in real time, and create counterfeit identity documents that pass visual checks.\n\nSecurity experts at Microsoft say AI is accelerating attack speed and lowering costs, forcing defenders to adapt. Attacks are no longer just targeting hardware but also AI systems themselves—model prompts, training data, and infrastructure. Mike Yeh, Microsoft’s vice president for customer security and trust, called for stronger public-private partnerships to address interconnected risks in an era where threats evolve faster than traditional defences.","keyPoints":["AI-powered voice scams over Teams rose 502% year-on-year, Microsoft reports","Over 46 million business contact impersonation attacks detected in the past 12 months","AI tools now generate voice clones, fake IDs, and target AI systems directly, per Microsoft"],"whyItMatters":"AI-driven voice scams are becoming more sophisticated and widespread, forcing businesses and governments to rethink security strategies.
