AI Outbound Number Spoofing Bulk Fraud: Carpet-bombing scams using virtual numbers and AI customer service agents to make thousands of calls daily

Who Gets Targeted

The primary victims are the general public and consumers. Relying on mobile communication and trusting caller ID, they often lower their guard once a call is connected. Scammers use spoofed local numbers and professional customer service scripts to create a sense of urgency or offer 'too good to be true' deals, exploiting the victims' pain points. Under conditions of information asymmetry, victims are easily deceived into believing in 'investment refunds,' 'mobile game coaching,' or 'premium services.'

骗局怎么运作

• Industry Chain Leasing and Number Spoofing: Scammers first rent number-changing software and virtual number pool equipment from gray-market channels. Through API layers, they spoof the caller ID to appear as a local number in the victim's city or the official customer service number of a well-known company. This technical approach bypasses basic carrier blocking systems, significantly increasing connection rates and lowering the victim's defenses.
• De-tagging Black Market and AI Humanoid Voice: To prevent numbers from being flagged as 'spam' by mobile security apps, scammers purchase 'de-tagging' services to batch-remove these warnings. Simultaneously, they use the latest low-cost AI voice synthesis models to generate highly realistic human voices with emotional inflection, capable of real-time interaction based on pre-set scripts, mimicking human agents.
• Script Customization and Carpet-bombing Calls: Using massive amounts of personal data obtained via web scraping or gray-market purchases, scammers tailor scripts for different demographics. They then use AI outbound systems to automatically dial numbers, with a single device capable of making over 1,500 calls per day. The system automatically filters out empty or unanswered numbers, and once a victim responds, the AI immediately initiates the corresponding scenario script.
• Precision Fraud Induction: Once the victim is engaged, the scammer pivots to the specific fraud scenario. If posing as game support, they induce top-ups under the guise of 'coaching for upgrades'; if posing as financial support, they induce the victim to click phishing links or download screen-sharing apps for 'refunds,' subsequently stealing bank card passwords and verification codes.
• Fund Transfer and Evidence Destruction: Once the victim transfers funds or provides sensitive verification information, the human-led black-market gang takes over, rapidly laundering the money through multi-layered 'money mule' accounts and cryptocurrency. Meanwhile, the AI outbound system immediately deletes the call logs and rotates to new spoofed numbers, cutting off tracking leads and creating significant challenges for police investigations and fund recovery.

红旗信号（看到这些快跑）

• 🚩 Although the caller ID shows a local number or a well-known company, there is often a faint static sound or a half-second delay upon answering—a hallmark of AI-driven bulk dialing.
• 🚩 The caller offers 'exclusive discounts,' 'refunds,' or 'game coaching,' but demands that you click an unknown SMS link or download an app not found in official app stores.
• 🚩 The caller asks for highly unreasonable personal information, such as full bank card passwords or SMS verification codes, and the AI's responses become stiff or repetitive if you hesitate or question them.
• 🚩 The same number calls multiple times in a very short period; if you hang up and immediately call back, you receive an 'empty number' or 'cannot be connected' message, indicating a dynamic or one-time virtual number.
• 🚩 The scammer accurately cites your name, recent consumption history, or even delivery information to build initial trust, but the conversation inevitably shifts to fund transfers or clicking external links.

How to Protect Yourself

• ✅ Carrier-side Blocking: Actively enable and use the 'High-Frequency Spam Call Blocking Service' provided by telecom operators to filter out high-risk outbound calls and virtual number segments at the system level.
• ✅ Callback Verification: Stay vigilant regarding unsolicited calls claiming to be from official customer service or local numbers. Do not follow instructions; hang up and call the official public number to verify.
• ✅ Security Software Protection: Install reputable security software on your phone, keep the database updated, and use its spam-tagging features to identify frequently reported spoofed numbers.
• ✅ Protect Core Privacy: Firmly refuse any requests for SMS verification codes, bank card passwords, or the downloading of external apps during a call. Never click on unknown links in SMS or social media messages.
