• Caller ID Spoofing: Scammers can call from unknown or spoofed numbers easily.

Data Inputs

• Publicly Available Audio: Scammers pull victim's voice samples from social media posts.

Human Factors

Process and Methods

• No Family Verification Code: Lack of a pre-arranged family codeword to verify identity.
• Easy Wire Transfer Processes: Financial systems allow rapid, irreversible international wires.

Regulatory Environment

• Lack of AI Voice Regulations: No strict legal controls on commercial voice cloning software.
