According to the Criminal Investigation Bureau of the Ministry of Public Security, during the May Day holiday, there was a high volume of passenger flow in railways, civil aviation, and other industries, leading to tight ticket sales. Flight delays, refunds, and changes were also common, which could provide opportunities for criminals to take advantage of. As a result, cases of telecom network fraud related to ticket refunds and changes may be on the rise. The public security organs remind that when receiving information about ticket refunds or changes, it is necessary to confirm the flight status through the airline's official app or customer service phone number, do not click on unfamiliar links, do not download unknown apps, do not enable "screen sharing" or disclose verification codes, and avoid operating outside the official platform. Be especially vigilant when receiving any proactive claims calls, verify through official channels, and protect your 'money bag'. (Looking into the New Era)
