Locky勒索软件潮来袭，请躲避

概述

自2月以来，360威胁情报中心监测到一大波勒索软件潮，国内单位组织陆续开始受到的冲击，公司对外的邮箱收到大量如下携带恶意附件的邮件。

邮件内容大致如下：

员工如不小心打开恶意附件，恶意软件会对外连接服务器下载组件，加密系统上的重要文件，要求用户付费解密。

样本行为分析

邮件附件为只有两个JS脚本的压缩包：

JS经过混淆，通过分析得知，受害者双击执行JS后创建MSXML2.XMLHTTP对象下载http://vaseline-amar-ujala.in/euwiyr4hdc可执行文件，并通过WScript.Shell对象的运行方法启动Locky主进程：

下载的EXE经过大量的混淆处理：

进程启动后将机器ID写入HKEY_CURRENT_USER \ SOFTWARE \ Locky \ ID，并将用到的加密公钥写入HKEY_CURRENT_USER \ SOFTWARE \ Locky \ PUBKEY：

随后木马开始遍历目录寻找的.xls，.PPT，.DOC，.wb2，.JPG，.WAV等文件格式，使用RSA加密为编号+哈希.locky文件，并在存在文档得目录下写入恢复指导文档：

完成加密后将HKEY_CURRENT_USER \ SOFTWARE \ Locky \完成设置为1，并通过加密的数据告知服务器：

如下是部分通信地址列表：

http://78.40.108.39/main.php

http://51.255.107.8/main.php

http://51.255.107.10/main.php

http://51.254.181.122/main.php

http://195.64.154.114/main.php

http://188.127.231.116/main.php

http://149.202.109.205/main.php

最后将桌面设置为恢复指导图，并弹出恢复指导文档，等待受害者交付赎金：

感染情况与建议

根据360威胁情报中心的数据，自3月以来确认中招的用户超过万人，淘宝上甚至已经出现协助代付款解密的服务。在此建议用户不要随意点击来源不明的邮件，目前360安全卫士已对此勒索软件做持续的查杀。

国际奥林匹克委员会

攻击者用于存放恶意代码的下载服务器大都是被攻陷的合法站点，以下是部分列表，请在边界设备上予以阻断。
