勒索病毒凶猛:上百国家遭“感染” 高校成重灾区

2017-05-14 03:15:13   

据媒体报道,中石油有关负责人表示,目前公司加油站的加油业务和现金支付业务正常运行,但是第三方支付无法使用,怀疑受到病毒攻击,具体情况还在核查处置中。

 上百国家和地区遭“感染”

病毒攻击并不仅局限在我国。今日,国家网络与信息安全信息通报中心紧急通报:5月12日20时许,新型“蠕虫”式勒索病毒爆发,目前已有100多个国家和地区的数万台电脑遭该勒索病毒感染。

今日凌晨,微博“英国那些事儿”发文,一个多小时前,英国16家医院遭到大范围网络攻击,医院内网被攻陷,电脑被锁定,电话打不通。黑客索要每家医院300比特币的赎金,否则将删除所有资料。这16家机构对外联系基本中断,内部恢复使用纸笔进行紧急预案。英国国家网络安全部门正在调查。

腾讯公司安全部门向新京报提供的数据显示,初步统计,该“蠕虫”已影响了约上百个国家的学校、医院、机场、银行、加油站等设备,使得这些设备上的文档资料全部被加密,损失惨重。

据IT之家消息,目前受感染地区主要集中在中国中部和东南沿海地区,欧洲大陆、美国五大湖地区。中国、欧洲大陆地区受到的感染情况最为严重。

揭秘1罪魁祸首是“永恒之蓝”病毒

今日上午,360公司董事长周鸿祎发微博称,此次校园网勒索病毒是由NSA泄露的“永恒之蓝”黑客武器传播的。“永恒之蓝”可远程攻击Windows的445端口(文件共享),如果系统没有安装今年3月的微软补丁,无需用户任何操作,只要开机上网,“永恒之蓝”就能在电脑里执行任意代码,植入勒索病毒等恶意程序。

国家互联网应急中心介绍,已着手对勒索软件及相关网络攻击活动进行监测,13日9时30分至12时,境内境外约101.1万个IP地址遭受“永恒之蓝”SMB漏洞攻击工具的攻击尝试,发起攻击尝试的IP地址(包括进行攻击尝试的主机地址及可能已感染蠕虫的主机地址)数量9300余个。

中心连发两条通报称,勒索软件利用此前披露的Windows SMB服务漏洞攻击手段,向终端用户进行渗透传播,并勒索比特币或其他价值物。包括高校、能源等重要信息系统在内的多个国内用户受到攻击,对我国互联网络构成较为严重的安全威胁。
