On the 18th, the Cybersecurity Bureau of the Ministry of Public Security released a typical case of online shopping fraud, reminding consumers to pay attention to telecommunications network fraud activities carried out in recent online shopping promotions. Case 1. Pre sale link: analysis of the trojan trap in the guise of "limited time discount": Ms. Li, a citizen, received the SMS link of "a brand 618 pre sale reduced by 300", and after clicking it, her mobile phone was implanted into the trojan, and the next day she found that the Alipay account was transferred 8000 yuan. Fraudulent logic: Criminals send text messages containing phishing links, which mimic legitimate e-commerce platforms and induce users to enter account passwords, verification codes, or directly download malicious programs. Case 2: Fake Red Envelope Rain: Analysis of the Information Harvester Trick Behind "Click to Receive 188 Yuan": The "618 National Red Envelope Demolition" link circulating on social media actually requires users to fill in "name+ID card+bank card" to complete "identity verification", and even induces the download of fraudulent apps. Police reminder: Such fraudulent activities occur during shopping festivals, and consumers need to be vigilant, avoid clicking on unknown red envelope links, and protect personal information security. Case 3: Customer Service "Warm hearted" Call: A typical dialogue from "Refund and Claims" to "Clearing Balance": "The cosmetics you purchased have detected problems and need to click the link to complete the refund" "The system mistakenly deducted your membership fee, provide your bank card number to help you recover it". High risk operation: Criminals obtain order information through illegal channels, impersonate customer service to guide users to enable "screen sharing" or enter verification codes, and achieve remote theft.
