A new generation of deepfake audio attacks is targeting corporate voice-verification systems and Help Desk personnel. Unlike previous 'replay' attacks, these 'Live-Synthesis' deepfakes allow attackers to carry out real-time conversations using the cloned voice of an executive or IT administrator. This technology significantly lowers the barrier for complex Social Engineering, such as requesting MFA resets or wire transfers. Organizations should move away from voice as a sole authentication factor and implement 'Out-of-Band' verification for sensitive requests, using physical tokens or pre-arranged security codes.
