Police analysis: Don't click and scan links and QR codes! This is a Trojan link.
After you scan the QR code or click on the link, the page prompts you to fill in information such as ID card, bank card and telephone number, and then you will receive a verification code. Liars will fool you into telling them the verification code (for example, for the reason of reissue the travel itinerary code) so as to transfer the money on your card.
In addition, there are scammers posing as "epidemic prevention agency personnel" to send messages in groups, falsely claiming that they can quickly detect nucleic acids. Nucleic acid testing must be carried out in qualified hospitals, professional medical institutions or third-party testing institutions certified by the health department! Don't trust other informal channels.
