云上勒索软件趋势及危害

受到勒索的主机数持续上涨借助比特币等数字货币的匿名性，勒索攻击在近年来快速兴起，给企业和个人带来了严重的威胁

越来越多的勒索病毒集成了丰富的攻击模块

云环境租户业务的多样性，不断出现的业务场景日趋复杂

企业安全意识不足，未做好口令管理和访问控制

勒索病毒危害严重勒索病毒会严重影响用户业务，带来严重的经济损失

关键文件被加密，影响企业业务

高额赎金，带来直接经济损失

数据被窃取，存在泄漏的风险

勒索软件常用手段

钓鱼邮件

攻击者通过伪造邮件，诱导用户下载邮件中的恶意勒索软件

社交网络传播

在社交网络信息中通过恶意链接诱导用户下载勒索软件

弱口令

用户服务器密码不强，通过密码暴力破解入侵服务器，植入勒索软件

漏洞/公开端口

用户服务器存在漏洞、对外开放的网络端口，被攻击者利用入侵植入勒索软件
