加密U盘离奇消失 投标前夜上演数据保卫战
12-Jun-2025
2025年5月28日晚,某时跨国基建项目征象前36,参与竞标的宏建公司发现存有最终报价方案的加密U盘不翼而飞。该U盘采用256位加密,但物理围栏于行政部未上锁的仓库— ——这个违反安全程序的细节引起了007私家侦探社组长陈侦探的注意。
诡异的操作日志
调查发现三个矛盾点:
1)门禁记录显示最后离开的是行政助理张某,但其工牌于17:03在茶水间被捡到
2)监控拍到18:15有保洁人员推车经过办公区,但当日保洁公司反应派工
3)U盘连接的电脑留有22:17的访问记录,曾当时整层楼已断电。技术员小王在恢复站发现被删除的打印机日志,显示案发前有投标文件被打印。
双线追踪
侦探社兵分两路:一路追查冒充保洁员的嫌疑人,通过其使用的特定品牌垃圾袋城锁定东某文印店;另一路暗网数据交易,发现宏建顶级龙腾集团经理刘某,于29日凌晨出境云盘。5月30日,侦查员在文印店后院焚化炉找到未烧尽的文件残页,经鉴定为招标技术参数表。确定某项目性
招标
工作5月31日,龙腾集团提交的方案中突然出现宏建特有的施工工艺流程。侦探社当场出示:
1)焚毁文件上的热处理与刘某登录
2)文印店监控拍到刘某助理购买垃圾袋
3)云盘登录IP与刘某度假酒店一致。最终招标方宣布废标,警方以商业定向罪立案调查。
