二、排查方法
（一）详细查看分析浏览器记录以及网络设备中近期流量和DNS请求记录，查看是否有以上恶意地址连接记录，如有条件可提取源IP、设备信息、连接时间等信息进行深入分析。
（二）在本单位应用系统中部署网络流量检测设备进行流量数据分析，追踪与上述网址和IP发起通信的设备网上活动痕迹。
（三）如果能够成功定位到遭受攻击的联网设备，可主动对这些设备进行勘验取证，进而组织技术分析。
三、处置建议
（一）对所有通过社交平台或电子邮件渠道接收的文件和链接保持高度警惕，重点关注其中来源未知或不可信的情况，不要轻易信任或打开相关文件。
（二）及时在威胁情报产品或网络出口防护设备中更新规则，坚决拦截以上恶意网址和恶意IP的访问。
（三）向公安机关及时报告，配合开展现场调查和技术溯源。
