macOS Red Teaming

Abusing MDMs

  • JAMF Pro: jamf checkJSSConnection

  • Kandji

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.

For red teaming in MacOS environments it's highly recommended to have some understanding of how the MDMs work:


Using MDM as a C2

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 And to run your own MDM for Apple devices you could use 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> to see if they have self-enrolment enabled. If they have it might ask for credentials to access.

You could use the script to perform a password spraying attack.

Moreover, after finding proper credentials you could be able to brute-force other usernames with the next form:

JAMF device Authentication

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/

JAMF Device Takeover

The JSS (Jamf Software Server) URL that jamf will use is located in /Library/Preferences/com.jamfsoftware.jamf.plist. This file basically contains the URL:

plutil -convert xml1 -o - /Library/Preferences/com.jamfsoftware.jamf.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.

# 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

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.

Secrets stealing

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 can listen for new files being added and new process arguments.

macOS Remote Access

And also about MacOS "special" network protocols:

macOS Network Services & Protocols

Active Directory

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:

389, 636, 3268, 3269 - Pentesting LDAPActive Directory Methodology88tcp/udp - Pentesting Kerberos

Some local MacOS tool that may also help you is dscl:

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: MacHound is an extension to the Bloodhound audting tool allowing collecting and ingesting of Active Directory relationships on MacOS hosts.

  • 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: JavaScript for Automation (JXA) tool to do Active Directory enumeration.

Domain Information

echo show | scutil


The three types of MacOS users are:

  • Local Users — Managed by the local OpenDirectory service, they aren’t connected in any way to the Active Directory.

  • Network Users — Volatile Active Directory users who require a connection to the DC server to authenticate.

  • Mobile Users — Active Directory users with a local backup for their credentials and files.

The local information about users and groups is stored in in the folder /var/db/dslocal/nodes/Default. 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.

In addition to using the HasSession and AdminTo edges, MacHound adds three new edges to the Bloodhound database:

  • CanSSH - entity allowed to SSH to host

  • CanVNC - entity allowed to VNC to host

  • CanAE - entity allowed to execute AppleEvent scripts on host

#User enumeration
dscl . ls /Users
dscl . read /Users/[username]
dscl "/Active Directory/TEST/All Domains" ls /Users
dscl "/Active Directory/TEST/All Domains" read /Users/[username]
dscacheutil -q user

#Computer enumeration
dscl "/Active Directory/TEST/All Domains" ls /Computers
dscl "/Active Directory/TEST/All Domains" read "/Computers/[compname]$"

#Group enumeration
dscl . ls /Groups
dscl . read "/Groups/[groupname]"
dscl "/Active Directory/TEST/All Domains" ls /Groups
dscl "/Active Directory/TEST/All Domains" read "/Groups/[groupname]"

#Domain Information
dsconfigad -show

Accessing the Keychain

The Keychain highly probably contains sensitive information that if accessed withuot generating a prompt could help to move forward a red team exercise:

macOS Keychain

External Services

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.

Misc Red Team techniques


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:
