星展集团控股（D05.SI）今日盘中大跌3%，引起市场广泛关注。这一显著跌幅与该银行最新披露的客户数据泄露事件密切相关。
根据新加坡网络安全局与金融管理局的联合声明，本地印刷公司Toppan Next Tech（TNT）遭受勒索软件攻击，导致约8200名星展银行客户的账单和信函信息可能外泄。这一安全事件主要影响星展唯高达（DBS Vickers）账户和Cashline贷款账户的客户。
星展银行强调，银行系统并未受到入侵，客户存款和资金依然安全。受影响的账单与信函不包含登录凭证、密码、身份证号码、存款余额或客户的整体资产信息。尽管如此，这一事件仍然引发了投资者对银行信息安全管理的担忧，进而导致股价下跌。目前，相关调查仍在进行中，市场将密切关注事态发展及其对星展集团长期声誉的潜在影响。
