AI Bulk Voice Marketing Scams: Using Synthesized Voices to Automatically Call and Defraud Victims of Money

Who Gets Targeted

The victims are primarily middle-aged and elderly individuals as well as urban residents lacking information security awareness, who have poor ability to distinguish caller ID and voice content. Upon hearing synthesized voices claiming to be civil servants, bank staff, or relatives and friends, they become nervous and urgent. Syndicates use number databases compiled from leaked information to make bulk calls, prioritizing older users or mobile numbers with recent financial transaction records, and using scripts such as 'account abnormalities' or 'unpaid taxes requiring payment' to extract ID numbers and bank card numbers. Typical losses include funds required to be transferred into 'safe accounts' or paid via QR codes, as well as continuously leaked personal information.

骗局怎么运作

• Bad actors first rent or self-build an AI voice synthesis platform through underground channels, upload a large number of preset scam scripts (such as impersonating banks, taxation offices, or courier services), and bind them to an automatic dialing system to simultaneously make bulk calls to tens of thousands of mobile numbers.
• The system uses a number database (acquired through leaked personal information or web scrapers) to automatically match target demographics, prioritizing high-risk elderly users or mobile numbers with recent financial transaction records to increase success rates.
• When the call is connected, the highly realistic synthesized voice explains emergency situations such as 'account abnormalities' or 'unpaid taxes requiring payment' in an official tone, guiding victims to provide sensitive information such as ID numbers and bank card numbers during the call.
• Subsequently, the scam script demands the victims immediately transfer funds to a so-called 'safe account' or pay via QR code, and even forge SMS verification codes to create a sense of authenticity.
• After the transfer is completed, the system automatically records successful cases and updates the script library for continuous iteration, forming a closed-loop, highly efficient scam pipeline.

红旗信号（看到这些快跑）

• 🚩 The caller ID shows a local number or official institution number, yet no call record was left through official channels.
• 🚩 The voice used during the call is extremely fluent with no obvious mechanical feel, but the content includes unconventional demands such as urgent payments or verification codes.
• 🚩 The other party repeats the same urging statements multiple times in a short period and refuses to accept a redial if disconnected.
• 🚩 The victim is asked to directly transfer money or scan a code without verifying identity, and the provided account is a third-party platform or personal account.
• 🚩 SMS links sent by the other party after the call point to non-official domains or require downloading unknown apps.

How to Protect Yourself

• ✅ Do not blindly trust caller ID information. When receiving voice calls involving funds or accounts, hang up proactively and verify through official customer service channels.
• ✅ Install and enable anti-harassment and AI voice recognition interception features provided by carriers, and regularly update the interception database.
• ✅ Remain vigilant against requests for identity information or verification codes from unfamiliar callers, and never disclose any personal sensitive information over the phone.
• ✅ If information has already been leaked or you suspect you have been scammed, immediately report it to local public security authorities and contact your bank to halt payments.
