Core Viewpoint - A significant number of credit card users from Shanghai Pudong Development Bank (SPDB) have reported unauthorized transactions on their cards, all occurring in Brazil, despite the users being located in various countries including Japan, Canada, New Zealand, and the United States [1][2][3]. Group 1: Incident Overview - Users have formed a social media group to share their experiences, revealing a pattern of diverse merchant categories for the unauthorized transactions, including construction materials, automotive services, and dining establishments [3]. - The number of affected users has rapidly increased from 11 on September 11 to over 340 by September 15 [3]. - The affected credit card is the "SPDB Mastercard Priceless World Card," and both SPDB and Mastercard have acknowledged the unauthorized transactions and initiated emergency responses [3]. Group 2: Transaction Patterns - The unauthorized transactions predominantly occurred between September 9 and September 11, with some users reporting identical transaction times [5]. - The amounts of the unauthorized transactions were similar, with most victims experiencing losses around 20,000 RMB, as the transactions were primarily under 5,000 Brazilian Reais (approximately 6,500 RMB) [7][8]. - The first transaction was typically a small amount, used to verify the card's functionality, while subsequent transactions exceeded the users' credit limits by 30% to 40% [8]. Group 3: Security Concerns - The incident is suspected to be a result of a hacker attack on the technical systems, highlighting the need for increased vigilance among banks, card issuers, and cardholders [4]. - Despite the use of chip cards, which are generally considered more secure, the incident suggests vulnerabilities in online transaction security [11][12]. - Users did not receive transaction notifications at the time of the unauthorized charges, only receiving notifications for the account debits, which is atypical for credit card transactions [9]. Group 4: Recommendations for Prevention - Users are advised to take immediate action by reporting unauthorized transactions and freezing their cards, while also collecting evidence of the fraudulent activities [12][13]. - Recommendations include disabling unnecessary payment channels, setting transaction alerts, and avoiding online payments over public Wi-Fi to mitigate risks [13][14]. - Users should also consider changing their cards upon returning to their home country to enhance security [15].
