病毒描述:

360安全大脑监测到通过”驱动人生”供应链攻击传播的挖矿木马在1月30日下午4时左右再次更新。此次更新中,木马在此前抓取系统帐户密码的基础上增加了抓取密码hash值的功能,并试图通过pass the hash攻击进行横向渗透,使得该木马的传播能力进一步加强,即使是有高强度口令的机器也有可能被攻陷。
pass the hash也称作哈希传递攻击,攻击者可以直接通过密码的哈希值访问远程主机或服务,而不用提供明文密码。攻击者使用pass the hash技术尝试在系统登录密码非弱口令并且无法抓取登录密码的情况下进行横向攻击,增加攻击成功率。
永恒之蓝下载器木马再次更新,此前攻击者针对驱动人生公司的供应链进行攻击,利用其软件升级通道下发永恒之蓝下载器木马,并利用其软件升级通道下发木马,在攻击模块中利用“永恒之蓝”漏洞攻击,造成短时间内大范围感染。事件发生之后,驱动人生公司对受到木马影响的升级通道进行了紧急关闭。

但该木马下载器的幕后控制者并没有就此放弃行动,而是借助其已经感染的机器进行持续攻击:包括通过云控指令下发挖矿模块,在中招机器安装多个服务以及通过添加计划任务获得持续执行的机会,后续版本在攻击模块新增SMB爆破、远程执行工具psexec攻击、利用Powershell版mimikatz获取密码,以增强其扩散传播能力。
2019年2月10日发现的更新版本中,我们发现攻击者再次对攻击模块进行升级,改变其木马生成方式为Pyinstaller,同时在打包的Python代码中新增了email、cookie、ftp、http相关功能文件。木马通过将程序安装至系统服务、计划任务从而可以开机启动同时每隔一段时间重复启动,获得在感染电脑持续驻留的机会。

查杀脚本功能

  1. 删除恶意进程、服务、计划任务、注册表项、恶意文件
  2. 删除无规则随机字符串服务
  3. 支持最老版本样本,及最新样本
  4. 由于该攻击样本不停变形增肥md5值一直在便,故采用md5黑名单+恶意证书方式来清理
  5. 由于该系列病毒不断变种,本脚本不保证有效清除,仅作为技术交流使用
