自9月25日起，多名中国银行信用卡用户反映其中行万事达卡在未出境、卡片未离身的情况下遭境外盗刷1。盗刷交易集中出现在巴西和乌拉圭等南美地区1，受影响卡片主要为中行长城卓隽万事达卡系列，这些卡片此前均曾绑定过Apple Pay1。
针对此事件，万事达卡和中国银行于9月29日作出回应，表示已解决此事件，将撤销盗刷交易，持卡人无需还款1。据披露，部分持卡人被盗刷金额合计11404.68巴西雷亚尔（约合人民币1.48万元），已于9月28日被退回1。
业内分析师推测，此次盗刷事件系黑产团伙通过"撞库攻击"方式批量生成卡号进行作案1。此前，浦发银行与万事达合作发行的"无价世界卡"也曾在巴西遭遇集中盗刷1。
Starting September 25, multiple Bank of China credit card users reported unauthorized transactions on their Bank of China Mastercard in overseas locations despite never leaving China and keeping their physical cards in their possession 1. The fraudulent charges were concentrated in South America, particularly in Brazil and Uruguay 1. The affected cards were primarily from the Bank of China Great Wall Zhuojun Mastercard series, and these cards had previously been linked to Apple Pay 1.
On September 29, both Mastercard and Bank of China responded to address the incident, confirming that all unauthorized transactions would be reversed and cardholders would not be required to repay any fraudulent charges 1. Some affected cardholders had been defrauded of a combined total of 11,404.68 Brazilian reais, equivalent to approximately 14,800 yuan, which was refunded on September 28 1. Industry analysts attributed the fraud to criminal organizations conducting "credential stuffing attacks" to generate card numbers in bulk for fraudulent transactions 1.
