Core Viewpoint - The article discusses the three main stages of telecom network fraud: the lead generation stage, the fraud stage, and the money laundering stage. It emphasizes the importance of vigilance in recognizing and avoiding potential scams. Group 1: Lead Generation Methods - The lead generation methods can be categorized into three types: phone and SMS leads, online network leads, and offline physical leads [1] - Common phone and SMS lead types include: 1. Numbers starting with 95, which may indicate overseas scam calls [3] 2. Numbers starting with 00 or +, which are likely international calls [3] 3. 400 numbers, typically used for customer service, which may also be scams [3] 4. 106 numbers, often used for mass SMS, which can contain phishing links [3] 5. Unknown numbers, which should be hung up immediately [3] - Scammers are using advanced technologies like GOIP and VOIP to disguise their calls as local numbers, making it easier for them to deceive victims [5] Group 2: Online Network Leads - Scammers utilize social media and live streaming platforms to promote investment courses, no-threshold part-time jobs, and high-paying overseas work opportunities [8] - They lure victims into private groups under the guise of investment guidance, often taking months to build trust before executing the scam [8] Group 3: Offline Physical Leads - Scammers may send unsolicited packages containing items with QR codes, enticing victims to scan them to receive more gifts [12] - Street vendors may offer free gifts in exchange for scanning QR codes, which can lead to scams [14] - Special QR codes on yellow cards, often associated with illicit services, are also used to attract victims [16] - All these methods aim to lead victims to scam groups or fraudulent platforms, where they may be manipulated into downloading scam apps or engaging in fraudulent activities [18] Group 4: Prevention Tips - The article provides a mnemonic for fraud prevention: do not trust unknown calls, do not click unknown links, do not disclose personal information, and verify before transferring money [18]
