记者从国家安全部了解到，NFC（近场通信技术）作为一种便捷的无线通信方式，已广泛应用于移动支付、门禁系统、交通卡以及设备间文件传输等场 景，让一些原先需要打开手机、输入密码的复杂操作仅需"贴一贴"就可完成。然而，这项"一触即通"的技术，也可能在无形中成为信息泄露乃至危害国家 安全的潜在渠道。 NFC的潜在安全风险 ——涉密信息泄露的"近距离通道"。NFC技术的"近场"特性使其在一定范围内，可与其他设备产生数据交互。政府机关、军工单位、科研院所等敏感区域 若有搭载NFC功能的存储介质，且未配备其他的防护措施，一旦被专业攻击者近距离接触，其中存储的工作数据、涉密文件等，会被他人在短时间内读取 复制，且该行为难以被常规安防手段察觉，最终造成"无感"泄密。 ——关键设施系统的"穿透式威胁"。NFC模块作为设备间数据交互的核心载体，若未采取有效加密防护措施，攻击者可能通过中间人攻击等方式截获传输 数据，引发后续篡改与植入风险。在金融领域，攻击者利用NFC窃取支付信息后，可模拟合法交易，进而在不知不觉中盗刷资金，给个人造成经济损失， 甚至威胁经济安全；在能源、交通等基础设施领域，攻击者可通过攻击NFC技术模块破解关键门禁 ...
