中国校园网络成勒索病毒重灾区 打开毕业论文要“赎金”

2017-05-14 09:45:14   央广网

央广网北京5月14日消息(记者王逸群)据中国之声《新闻纵横》报道,昨天,英国、意大利、俄罗斯等全球多个国家爆发勒索病毒攻击,中国校园网络也成为重灾区,不少高校的学生打开自己的电脑后,发现系统内的各种文档文件都被锁定了,而屏幕正中出现的红色弹窗则提示:如果想要“解锁”被加密的文件,请支付300美金或者等值比特币,如果超过三天未支付,价格翻倍;如果超过一周未支付则文件会被永远清除。

进入5月份毕业答辩季节来临,不少学生电脑里的答辩论文也不幸“中招”无法打开。据不完全统计,已经有几十所高校发布了防范勒索病毒软件的通知,上百万高校生的电脑或面临风险。这个所谓的“勒索病毒”到底是什么?为什么受影响的电脑大多来自高校?面对大面积突发病毒感染,到底有没有解决办法?

桂林理工大学学生月霞昨晚在班级群里接到了学校保卫处发来的防范病毒的通知,之后她从周围的同学打听到,部分同学的电脑已经因感染病毒被锁定了诸多重要文件。

记者通过微博从全国多所大学学生了解到,该病毒大约是12号晚间出现的。一位名叫“长歌”的南昌大学本科生表示,今早打开电脑就发现被黑,不少人的毕业论文、毕业设计和答辩PPT全被锁定因此很着急。该校另一位微博名叫“小杰”的医学学生也透露,有大四的学长学姐已经向公安机关反映。南昌大学研究生王楠透露,虽然身边有同学中招,但是大家并没有支付所谓“赎金”。

山东大学张渊博同学告诉记者,勒索病毒还感染了学校的公共电脑,他们没法预约图书馆的座位了。

中国网络安全公司360首席安全工程师郑文彬透露,该病毒来源于美国国家安全局网络武器库。前段时间美国国家安全局漏洞攻击武器被泄露了,国外的黑客把攻击武器和他们的勒索软件组装起来变成一个蠕虫病毒,只要你的电脑没有打补丁开放在外网,就会被远程攻击。

记者梳理发现,包括河南大学、中山大学、南昌大学等几十所高校都已经发布了该病毒的预警防范通知。国际关系学院网络与教育技术中心负责人王标告诉记者,该病毒软件危害大、波及面广,但是学校已经做好充分防范措施。他介绍,近期国内多所院校出现ONION勒索软件感染情况,磁盘文件会被病毒加密为.onion后缀,只有支付高额赎金才能解密恢复文件,对学校各个业务系统和师生的个人数据造成严重损失。本轮攻击黑客利用微软MS17-010漏洞发起的,它危害大、波及面广,高校是本轮攻击重灾区之一。上次出现此漏洞,该校网络安全保障团队已对服务器端进行防范部署工作,所以系统风险基本可控。
