If you manage to **compromise admin credentials** to access the management platform, you can **potentially compromise all the computers** by distributing your malware in the machines.
A MDM will have permission to install, query or remove profiles, install applications, create local admin accounts, set firmware password, change the FileVault key...
In order to run your own MDM you need to **your CSR signed by a vendor** which you could try to get with [**https://mdmcert.download/**](https://mdmcert.download/). And to run your own MDM for Apple devices you could use [**MicroMDM**](https://github.com/micromdm/micromdm).
However, to install an application in an enrolled device, you still need it to be signed by a developer account... however, upon MDM enrolment the **device adds the SSL cert of the MDM as a trusted CA**, so you can now sign anything.
To enrol the device in a MDM you. need to install a **`mobileconfig`** file as root, which could be delivered via a **pkg** file (you could compress it in zip and when downloaded from safari it will be decompressed).
**Mythic agent Orthrus** uses this technique.
### Abusing JAMF PRO
JAMF can run **custom scripts** (scripts developed by the sysadmin), **native payloads** (local account creation, set EFI password, file/process monitoring...) and **MDM** (device configurations, device certificates...).
#### JAMF self-enrolment
Go to a page such as `https://<company-name>.jamfcloud.com/enroll/` to see if they have **self-enrolment enabled**. If they have it might **ask for credentials to access**.
You could use the script [**JamfSniper.py**](https://github.com/WithSecureLabs/Jamf-Attack-Toolkit/blob/master/JamfSniper.py) to perform a password spraying attack.
Moreover, after finding proper credentials you could be able to brute-force other usernames with the next form:
The **`jamf`** binary contained the secret to open the keychain which at the time of the discovery was **shared** among everybody and it was: **`jk23ucnq91jfu9aj`**.\
Moreover, jamf **persist** as a **LaunchDaemon** in **`/Library/LaunchAgents/com.jamf.management.agent.plist`**
So, an attacker could drop a malicious package (`pkg`) that **overwrites this file** when installed setting the **URL to a Mythic C2 listener from a Typhon agent** to now be able to abuse JAMF as C2.
{% code overflow="wrap" %}
```bash
# After changing the URL you could wait for it to be reloaded or execute:
sudo jamf policy -id 0
# TODO: There is an ID, maybe it's possible to have the real jamf connection and another one to the C2
```
{% endcode %}
#### JAMF Impersonation
In order to **impersonate the communication** between a device and JMF you need:
* The **UUID** of the device: `ioreg -d2 -c IOPlatformExpertDevice | awk -F" '/IOPlatformUUID/{print $(NF-1)}'`
* The **JAMF keychain** from: `/Library/Application\ Support/Jamf/JAMF.keychain` which contains the device certificate
With this information, **create a VM** with the **stolen** Hardware **UUID** and with **SIP disabled**, drop the **JAMF keychain,****hook** the Jamf **agent** and steal its information.
You could also monitor the location `/Library/Application Support/Jamf/tmp/` for the **custom scripts** admins might want to execute via Jamf as they are **placed here, executed and removed**. These scripts **might contain credentials**.
However, **credentials** might be passed tho these scripts as **parameters**, so you would need to monitor `ps aux | grep -i jamf` (without even being root).
The script [**JamfExplorer.py**](https://github.com/WithSecureLabs/Jamf-Attack-Toolkit/blob/master/JamfExplorer.py) can listen for new files being added and new process arguments.
In some occasions you will find that the **MacOS computer is connected to an AD**. In this scenario you should try to **enumerate** the active directory as you are use to it. Find some **help** in the following pages:
dscl "/Active Directory/[Domain]/All Domains" ls /
```
Also there are some tools prepared for MacOS to automatically enumerate the AD and play with kerberos:
* [**Machound**](https://github.com/XMCyber/MacHound): MacHound is an extension to the Bloodhound audting tool allowing collecting and ingesting of Active Directory relationships on MacOS hosts.
* [**Bifrost**](https://github.com/its-a-feature/bifrost): Bifrost is an Objective-C project designed to interact with the Heimdal krb5 APIs on macOS. The goal of the project is to enable better security testing around Kerberos on macOS devices using native APIs without requiring any other framework or packages on the target.
* [**Orchard**](https://github.com/its-a-feature/Orchard): JavaScript for Automation (JXA) tool to do Active Directory enumeration.
For example, the info about user called _mark_ is stored in _/var/db/dslocal/nodes/Default/users/mark.plist_ and the info about the group _admin_ is in _/var/db/dslocal/nodes/Default/groups/admin.plist_.
More info in [https://its-a-feature.github.io/posts/2018/01/Active-Directory-Discovery-with-a-Mac/](https://its-a-feature.github.io/posts/2018/01/Active-Directory-Discovery-with-a-Mac/)
The Keychain highly probably contains sensitive information that if accessed withuot generating a prompt could help to move forward a red team exercise:
MacOS Red Teaming is different from a regular Windows Red Teaming as usually **MacOS is integrated with several external platforms directly**. A common configuration of MacOS is to access to the computer using **OneLogin synchronised credentials, and accessing several external services** (like github, aws...) via OneLogin:
When a file is downloaded in Safari, if its a "safe" file, it will be **automatically opened**. So for example, if you **download a zip**, it will be automatically decompressed:
