外媒:勒索病毒袭击多国 俄被指与黑客有关

2017-05-14 19:46:11   参考消息

网络安全软件制造商赛门铁克公司调研经理维克拉姆·塔库尔说,尽管如此,由于黑客是从欧洲开始进行网络攻击的,所以设在美国的机构只有少数受到了影响。

塔库尔说,等黑客开始把注意力转向美国时,垃圾邮件过滤器已发现了这个新的威胁,并将负载恶意软件的邮件标记为恶意邮件。

窃取间谍“工具”

私人安全公司确认这种勒索软件是WannaCry病毒的新变体,它可以利用微软“视窗”操作系统中一个已知病毒,自动在大型网络中进行传播。

网络安全公司“众击”网络安全服务公司的研究人员亚当·迈耶斯说:“一旦进入,它就开始在系统中移动且无法阻止。”

若干私人网络安全公司的研究人员说,尚未宣称此事为其所干或是已被确认身份的黑客,很可能利用了美国国家安全局一种叫做“永恒之蓝”的密码,把它变成一种“蠕虫”病毒,或是自行传播的恶意软件。上月,“影子经纪人”组织公布了“永恒之蓝”密码。

Splunk公司威胁研究处主任里奇·巴杰说:“这是网络界遇到的一次最大规模的全球勒索软件袭击。”

“影子经纪人”组织公布“永恒之蓝”属于黑客工具宝库,他们说这是美国国家安全局开发的。

微软公司今天说,它即将推出“视窗”操作系统自动更新,防止用户受到病毒的侵害。微软公司3月14日曾发行了系统补丁,防止操作系统受到“永恒之蓝”的入侵。

俄罗斯又“躺枪”

据美国《纽约时报》网站5月13日报道,计算机安全专家正努力遏制波及全球的新一轮网络攻击的影响。网络病毒这次要求用户支付赎金,否则消除计算机里的数据。

俄罗斯、中国、印度等发展中国家遭受了严重打击,突出反映了非法软件的问题。因为盗版软件往往更容易沦为恶意软件的侵害对象。不过,这次就连正版软件的用户都未能幸免。如果没有安装近日发布的一个安全更新,正版用户同样容易遭到攻击。这说明全球网络太容易受到黑客与投机分子的影响。

另据英国《每日电讯报》网站5月12日报道,一个可能与俄罗斯有关的网络团伙被指与全世界范围内的电脑安全漏洞有关,他们或许是为了报复美国在叙利亚的空袭行动。

这个被称为“影子经纪人”的神秘组织4月曾声称,它从美国一个间谍机构窃取了一种“网络武器”,利用这一武器可以前所未有地进入使用微软“视窗”系统的所有电脑。

就在特朗普总统下令轰炸叙利亚一周后,这个组织于4月14日在一个不知名的网站上“丢弃了”这个电脑病毒。

一些专家认为,这个时机非常重要,并暗示“影子经纪人”与俄罗斯政府有瓜葛。
