欧盟警方:勒索软件网络袭击可能进一步升级

延伸阅读:上海就勒索软件发出预警:已构成较严重安全威胁

5月12日,互联网上出现针对Windows操作系统的勒索软件(Wannacry)攻击案例。目前,包括高校、能源等重要信息系统在内的多类用户受到攻击,已对我国互联网络构成较为严重的安全威胁。

上海市互联网信息办公室13日表示,该勒索软件利用已披露的Windows SMB服务漏洞(对应微软漏洞公告:MS17-010)攻击手段,对计算机中的文档、图片等实施高强度加密,并向用户勒索赎金。市网信办已于13日下午向本市各关键信息基础设施单位发出预警,各单位一旦发现感染,要及时报告相关情况,并开展应急处置。

上海市网信办建议广大互联网用户:

[1]升级Windows操作系统,目前微软公司已发布相关补丁程序MS17-010,可通过微软公司正规渠道进行升级。

[2]安装并及时更新杀毒软件。

[3]不要轻易打开来源不明的电子邮件。

[4]及时关闭计算机、网络设备上的445端口。

[5]要切实做好内网的安全管理,关闭非必需端口,及时升级,严格做好内外网隔离。

[6]定期在不同的存储介质上备份计算机上的重要文件。

[7]切勿轻信网上所谓的有偿解密方法、渠道,小心网络诈骗分子利用这次事件招摇撞骗。
