Shanghai Suishenma Airport

A massive data breach involving the Shanghai Suishenma health code system surfaced when a hacker offered a database allegedly containing personal information of nearly 48.5 million users. The Suishenma system is the health code application used in Shanghai for travel and public access during the pandemic. The leaked data reportedly includes names, phone numbers, identification numbers, and health code status. This incident highlights significant vulnerabilities in government digital infrastructure and personal data management during the COVID-19 response era. The breach was discovered after a threat actor posted the dataset for sale on a dark web forum for approximately 4000 US dollars.
