MacOS Security & Privilege Escalation

First of all, please note that most of the tricks about privilege escalation affecting Linux/Unix will affect also MacOS machines. So see:

Security Restrictions


Gatekeeper is designed to ensure that, by default, only trusted software runs on a user’s Mac. Gatekeeper is used when a user downloads and opens an app, a plug-in or an installer package from outside the App Store. Gatekeeper verifies that the software is from an identified developer, is notarised by Apple to be free of known malicious content, and hasn’t been altered. Gatekeeper also requests user approval before opening downloaded software for the first time to make sure the user hasn’t been tricked into running executable code they believed to simply be a data file.

Gatekeeper builds upon File Quarantine. Upon download of an application, a particular extended file attribute ("quarantine flag") can be added to the downloaded file. This attribute is added by the application that downloads the file, such as a web browser or email client, but is not usually added by others like common BitTorrent client software. When a user executes a "quarentined" file, Gatekeeper is the one that performs the mentioned actions to allow the execution of the file.

It's possible to check it's status and enable/disable (root required) with:

spctl --status
assessments enabled
spctl --enable
spctl --disable
#You can also allow nee identifies to execute code using the binary "spctl"

You can also find if a file has the quarantine extended attribute with:

xattr portada.png

Check the value of the extended attributes with:

xattr -l portada.png
00000000 03 00 53 DA 55 1B AE 4C 4E 88 9D CA B7 5C 50 F3 |..S.U..LN.....P.|
00000010 16 94 03 00 27 63 64 97 98 FB 4F 02 84 F3 D0 DB |....'cd...O.....|
00000020 89 53 C3 FC 03 00 27 63 64 97 98 FB 4F 02 84 F3 |.S....'cd...O...|
00000030 D0 DB 89 53 C3 FC 00 00 00 00 00 00 00 00 00 00 |...S............|
00000040 00 00 00 00 00 00 00 00 |........|
00000048 0081;607842eb;Brave;F643CD5F-6071-46AB-83AB-390BA944DEC5

And remove that attribute with:

xattr -d portada.png
#You can also remove this attribute from every file with
find . -iname '*' -print0 | xargs -0 xattr -d

And find all the quarantined files with:

find / -exec ls -ld {} \; 2>/dev/null | grep -E "[x\-]@ " | awk '{printf $9; printf "\n"}' | xargs -I {} xattr -lv {} | grep ""


X-Protect is Apple’s built in malware scanner. It keeps track of known malware hashes and patterns. You can get information about the latest XProtect update running:

system_profiler SPInstallHistoryDataType 2>/dev/null | grep -A 4 "XProtectPlistConfigData" | tail -n 5


MacOS Sandbox works with the kernel extension Seatbelt. It makes applications run inside the sandbox need to request access to resources outside of the limited sandbox. This helps to ensure that the application will be accessing only expected resources and if it wants to access anything else it will need to ask for permissions to the user.

Important system services also run inside their own custom sandbox such as the mdnsresponder service. You can view these custom sandbox profiles inside the /usr/share/sandbox directory. Other sandbox profiles can be checked in

Check some of the already given permissions to apps in System Preferences --> Security & Privacy --> Privacy --> Files and Folders.

To start an application with a sandbox config you can use:

sandbox-exec -f /Path/To/The/Application

Note that the Apple-authored software that runs on Windows doesn’t have additional security precautions, such as application sandboxing.

SIP - System Integrity Protection

This protection was enabled to help keep root level malware from taking over certain parts of the operating system. Although this means applying limitations to the root user many find it to be worthwhile trade off. The most notable of these limitations are that users can no longer create, modify, or delete files inside of the following four directories in general:

  • /System

  • /bin

  • /sbin

  • /usr

Note that there are exceptions specified by Apple: The file /System/Library/Sandbox/rootless.conf holds a list of files and directories that cannot be modified. But if the line starts with an asterisk it means that it can be modified as exception. For example, the config lines:

* /usr/libexec/cups
* /usr/local
* /usr/share/man

Means that /usr cannot be modified except for the 3 allowed folders allowed.

The final exception to these rules is that any installer package signed with the Apple’s certificate can bypass SIP protection, but only Apple’s certificate. Packages signed by standard developers will still be rejected when trying to modify SIP protected directories.

Note that if a file is specified in the previous config file but it doesn't exist, it can be created. This might be used by malware to obtain stealth persistence. For example, imagine that a .plist in /System/Library/LaunchDaemons appears listed but it doesn't exist. A malware may create one and use it as persistence mechanism.

Also, not how files and directories specified in rootless.conf have a rootless extended attribute:

xattr /System/Library/LaunchDaemons/
ls -lO /System/Library/LaunchDaemons/
[email protected] 1 root wheel restricted,compressed 412 1 Jan 2020 /System/Library/LaunchDaemons/

SIP handles a number of other limitations as well. Like it doesn't allows for the loading of unsigned kexts. SIP is also responsible for ensuring that no OS X system processes are debugged. This also means that Apple put a stop to dtrace inspecting system processes.

Check if SIP is enabled with:

csrutil status
System Integrity Protection status: enabled.

If you want to disable it, you need to put the computer in recovery mode (start it pressing command+R) and execute: csrutil disable

Common users

  • Daemon: User reserved for system daemons

  • Guest: Account for guests with very strict permissions

  • Nobody: Processes are executed with this user when minimal permissions are required

  • Root

File ACLs

When the file contains ACLs you will find a "+" when listing the permissions like in:

ls -ld Movies
drwx------+ 7 username staff 224 15 Apr 19:42 Movies

You can read the ACLs of the file with:

ls -lde Movies
drwx------+ 7 username staff 224 15 Apr 19:42 Movies
0: group:everyone deny delete

You can find all the files with ACLs with (this is veeery slow):

ls -RAle / 2>/dev/null | grep -E -B1 "\d: "

Resource Forks or MacOS ADS

This is a way to obtain Alternate Data Streams in MacOS machines. You can save content inside an extended attribute called inside a file by saving it in file/..namedfork/rsrc.

echo "Hello" > a.txt
echo "Hello Mac ADS" > a.txt/..namedfork/rsrc
xattr -l a.txt #Read extended attributes Hello Mac ADS
ls -l a.txt #The file length is still q
[email protected] 1 username wheel 6 17 Jul 01:15 a.txt

You can find all the files containing this extended attribute with:

find / -type f -exec ls -ld {} \; 2>/dev/null | grep -E "[x\-]@ " | awk '{printf $9; printf "\n"}' | xargs -I {} xattr -lv {} | grep ""

OS X Specific Extensions

  • .dmg: Apple Disk Image files are very frequent for installers.

  • .kext: It must follow a specific structure and it's the OS X version of a driver.

  • .plist: Also known as property list stores information in XML or binary format.

    • Can be XML or binary. Binary ones can be read with:

      • defaults read config.plist

      • /usr/libexec/PlistBuddy -c print config.plsit

      • plutil -p config.plist

  • .app: Apple applications that follows directory structure.

  • .dylib: Dynamic libraries (like Windows DLL files)

  • .pkg: Are the same as xar (eXtensible Archive format). The installer command can be use to install the contents of these files.

File hierarchy layout

  • /Applications: The installed apps should be here. All the users will be able to access them.

  • /bin: Command line binaries

  • /cores: If exists, it's used to store core dumps

  • /dev: Everything is treated as a file so you may see hardware devices stored here.

  • /etc: Configuration files

  • /Library: A lot of subdirectories and files related to preferences, caches and logs can be found here. A Library folder exists in root and on each user's directory.

  • /private: Undocumented but a lot of the mentioned folders are symbolic links to the private directory.

  • /sbin: Essential system binaries (related to administration)

  • /System: File fo making OS X run. You should find mostly only Apple specific files here (not third party).

  • /tmp: Files are deleted after 3 days (it's a soft link to /private/tmp)

  • /Users: Home directory for users.

  • /usr: Config and system binaries

  • /var: Log files

  • /Volumes: The mounted drives will apear here.

  • /.vol: Running stat a.txt you obtain something like 16777223 7545753 -rw-r--r-- 1 username wheel ... where the first number is the id number of the volume where the file exists and the second one is the inode number. You can access the content of this file through /.vol/ with that information running cat /.vol/16777223/7545753

Special MacOS files and folders

  • .DS_Store: This file is on each directory, it saves the attributes and customisations of the directory.

  • .Spotlight-V100: This folder appears on the root directory of every volume on the system.

  • .metadata_never_index: If this file is at the root of a volume Spotlight won't index that volume.

  • <name>.noindex: Files and folder with this extension won't be indexed by Spotlight.

  • $HOME/Library/Preferences/ Contains information about downloaded files, like the URL from where they were downloaded.

  • /var/log/system.log: Main log of OSX systems. is responsible for the execution of syslogging (you can check if it's disabled looking for "" in launchctl list.

  • /private/var/log/asl/*.asl: These are the Apple System Logs which may contain interesting information.

  • $HOME/Library/Preferences/ Stores recently accessed files and applications through "Finder".

  • $HOME/Library/Preferences/ Stores items to launch upon system startup

  • $HOME/Library/Logs/DiskUtility.log: Log file for thee DiskUtility App (info about drives, including USBs)

  • /Library/Preferences/SystemConfiguration/ Data about wireless access points.

  • /private/var/db/launchd.db/ List of daemons deactivated.

  • /private/etc/kcpassword: If autologin is enabled this file will contain the users login password XORed with a key.

Auto Start Extensibility Point (ASEP)

An ASEP is a location on the system that could lead to the execution of a binary without user interaction. The main ones used in OS X take the form of plists.


launchd is the first process executed by OX S kernel at startup and the last one to finish at shut down. It should always have the PID 1. This process will read and execute the configurations indicated in the ASEP plists in:

  • /Library/LaunchAgents: Per-user agents installed by the admin

  • /Library/LaunchDaemons: System-wide daemons installed by the admin

  • /System/Library/LaunchAgents: Per-user agents provided by Apple.

  • /System/Library/LaunchDaemons: System-wide daemons provided by Apple.

When a user logs in the plists located in /Users/$USER/Library/LaunchAgents are started with the logged users permissions.

The main difference between agents and daemons is that agents are loaded when the user logs in and the daemons are loaded at system startup (as there are services like ssh that needs to be executed before any user access the system). Also agents may use GUI while daemons need to run in the background.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN">
<plist version="1.0">
<key>RunAtLoad</key><true/> <!--Execute at system startup-->
<integer>800</integer> <!--Execute each 800s-->
<key>SuccessfulExit</key></false> <!--Re-execute if exit unsuccessful-->
<!--If previous is true, then re-execute in successful exit-->

There are cases where an agent needs to be executed before the user logins, these are called PreLoginAgents. For example, this is useful to provide assistive technology at login. They can be found also in /Library/LaunchAgents(see here an example).

New Daemons or Agents config files will be loaded after next reboot or using launchctl load <target.plist> It's also possible to load .plist files without that extension with launchctl -F <file> (however those plist files won't be automatically loaded after reboot). It's also possible to unload with launchctl unload <target.plist> (the process pointed by it will be terminated),

To ensure that there isn't anything (like an override) preventing an Agent or Daemon from running run: sudo launchctl load -w /System/Library/LaunchDaemos/

List all the agents and daemons loaded by the current user:

launchctl list


List the cron jobs of the current user with:

crontab -l

You can also see all the cron jobs of the users in /usr/lib/cron/tabs/ and /var/at/tabs/ (needs root).


In order to install a KEXT as a startup item, it needs to be installed in one of the following locations:

  • /System/Library/Extensions

    • KEXT files built into the OS X operating system.

  • /Library/Extensions

    • KEXT files installed by 3rd party software

You can list currently loaded kext files with:

kextstat #List loaded kext
kextload /path/to/kext.kext #Load a new one based on path
kextload -b #Load a new one based on path
kextunload /path/to/kext.kext
kextunload -b

For more information about kernel extensions check this section.

Login Items

In System Preferences -> Users & Groups -> Login Items you can find items to be executed when the user logs in. It it's possible to list them, add and remove from the command line:

#List all items:
osascript -e 'tell application "System Events" to get the name of every login item'
#Add an item:
osascript -e 'tell application "System Events" to make login item at end with properties {path:"/path/to/itemname", hidden:false}'
#Remove an item:
osascript -e 'tell application "System Events" to delete login item "itemname"'

These items are stored in the file /Users/<username>/Library/Application Support/


“At tasks” are used to schedule tasks at specific times. These tasks differ from cron in that they are one time tasks that get removed after executing. However, they will survive a system restart so they can’t be ruled out as a potential threat.

By default they are disabled but the root user can enable them with:

sudo launchctl load -F /System/Library/LaunchDaemons/

This will create a file at 13:37:

echo hello > /tmp/hello | at 1337

If AT tasks aren't enabled the created tasks won't be executed.

Login/Logout Hooks

They are deprecated but can be used to execute commands when a user logs in.

cat > $HOME/ << EOF
echo 'My is: \`id\`' > /tmp/login_id.txt
chmod +x $HOME/
defaults write LoginHook /Users/$USER/

This setting is stored in /Users/$USER/Library/Preferences/

defaults read /Users/$USER/Library/Preferences/
LoginHook = "/Users/username/";
MiniBuddyLaunch = 0;
TALLogoutReason = "Shut Down";
TALLogoutSavesState = 0;
oneTimeSSMigrationComplete = 1;

To delete it:

defaults delete LoginHook

In the previous example we have created and deleted a LoginHook, it's also possible to create a LogoutHook.

The root user one is stored in /private/var/root/Library/Preferences/

Startup Items

This is deprecated, so nothing should be found in the following directories.

A StartupItem is a directory that gets placed in one of these two folders. /Library/StartupItems/ or /System/Library/StartupItems/

After placing a new directory in one of these two locations, two more items need to be placed inside that directory. These two items are a rc script and a plist that holds a few settings. This plist must be called “StartupParameters.plist”.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "">
<plist version="1.0">
<string>This is a description of this service</string>
<string>None</string> <!--Other req services to execute before this -->
<string>superservicename</string> <!--Name of the services provided by this file -->
. /etc/rc.common
touch /tmp/superservicestarted
rm /tmp/superservicestarted
echo "Restarting"
RunService "$1"


It's also possible to place here commands that will be executed at startup. Example os regular rc.common script:

# Common setup for startup scripts.
# Copyright 1998-2002 Apple Computer, Inc.
# Configure the shell #
# Be strict
#set -e
set -u
# Set command search path
PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/libexec:/System/Library/CoreServices; export PATH
# Set the terminal mode
#if [ -x /usr/bin/tset ] && [ -f /usr/share/misc/termcap ]; then
# TERM=$(tset - -Q); export TERM
# Useful functions #
# Determine if the network is up by looking for any non-loopback
# internet network interfaces.
local test
if [ -z "${NETWORKUP:=}" ]; then
test=$(ifconfig -a inet 2>/dev/null | sed -n -e '/' -e '/' -e '/inet/p' | wc -l)
if [ "${test}" -gt 0 ]; then
alias ConsoleMessage=echo
# Process management
GetPID ()
local program="$1"
local pidfile="${PIDFILE:=/var/run/${program}.pid}"
local pid=""
if [ -f "${pidfile}" ]; then
pid=$(head -1 "${pidfile}")
if ! kill -0 "${pid}" 2> /dev/null; then
echo "Bad pid file $pidfile; deleting."
rm -f "${pidfile}"
if [ -n "${pid}" ]; then
echo "${pid}"
return 0
return 1
# Generic action handler
RunService ()
case $1 in
start ) StartService ;;
stop ) StopService ;;
restart) RestartService ;;
* ) echo "$0: unknown argument: $1";;

Memory Artifacts

Swap Files

  • /private/var/vm/swapfile0: This file is used as a cache when physical memory fills up. Data in physical memory will be pushed to the swapfile and then swapped back into physical memory if it’s needed again. More than one file can exist in here. For example, you might see swapfile0, swapfile1, and so on.

  • /private/var/vm/sleepimage: When OS X goes into hibernation, data stored in memory is put into the sleepimage file. When the user comes back and wakes the computer, memory is restored from the sleepimage and the user can pick up where they left off.

    By default in modern MacOS systems this file will be encrypted, so it might be not recuperable.

    • However, the encryption of this file might be disabled. Check the out of sysctl vm.swapusage.

Dumping memory with osxpmem

In order to dump the memory in a MacOS machine you can use osxpmem.

#Dump raw format
sudo --format raw -o /tmp/dump_mem
#Dump aff4 format
sudo -o /tmp/dump_mem.aff4

If you find this error: failed to load - (libkern/kext) authentication failure (file ownership/permissions); check the system/kernel logs for errors or try kextutil(8) You can fix it doing:

sudo cp -r "/tmp/"
sudo kextutil "/tmp/MacPmem.kext"
#Allow the kext in "Security & Privacy --> General"
sudo --format raw -o /tmp/dump_mem

Other errors might be fixed by allowing the load of the kext in "Security & Privacy --> General", just allow it.

You can also use this oneliner to download the application, load the kext and dump the memory:

cd /tmp; wget; unzip; chown -R root:wheel; kextload; --format raw -o /tmp/dump_mem

User Privileges

  • Standard User: The most basic of users. This user needs permissions granted from an admin user when attempting to install software or perform other advanced tasks. They are not able to do it on their own.

  • Admin User: A user who operates most of the time as a standard user but is also allowed to perform root actions such as install software and other administrative tasks. All users belonging to the admin group are given access to root via the sudoers file.

  • Root: Root is a user allowed to perform almost any action (there are limitations imposed by protections like System Integrity Protection).

    • For example root won't be able to place a file inside /System


Shadow Passwords

Shadow password is stored withe the users configuration in plists located in /var/db/dslocal/nodes/Default/users/. The following oneliner can be use to dump all the information about the users (including hash info):

for l in /var/db/dslocal/nodes/Default/users/*; do if [ -r "$l" ];then echo "$l"; defaults read "$l"; fi; done

Scripts like this one or this one can be used to transform the hash to hashcat format.

The attacker still needs to gain access to the system as well as escalate to root privileges in order to run keychaindump. This approach comes with its own conditions. As mentioned earlier, upon login your keychain is unlocked by default and remains unlocked while you use your system. This is for convenience so that the user doesn’t need to enter their password every time an application wishes to access the keychain. If the user has changed this setting and chosen to lock the keychain after every use, keychaindump will no longer work; it relies on an unlocked keychain to function.

It’s important to understand how Keychaindump extracts passwords out of memory. The most important process in this transaction is the ”securityd“ process. Apple refers to this process as a security context daemon for authorization and cryptographic operations. The Apple developer libraries don’t say a whole lot about it; however, they do tell us that securityd handles access to the keychain. In his research, Juuso refers to the key needed to decrypt the keychain as ”The Master Key“. A number of steps need to be taken to acquire this key as it is derived from the user’s OS X login password. If you want to read the keychain file you must have this master key. The following steps can be done to acquire it. Perform a scan of securityd’s heap (keychaindump does this with the vmmap command). Possible master keys are stored in an area flagged as MALLOC_TINY. You can see the locations of these heaps yourself with the following command:

sudo vmmap <securityd PID> | grep MALLOC_TINY

Keychaindump will then search the returned heaps for occurrences of 0x0000000000000018. If the following 8-byte value points to the current heap, we’ve found a potential master key. From here a bit of deobfuscation still needs to occur which can be seen in the source code, but as an analyst the most important part to note is that the necessary data to decrypt this information is stored in securityd’s process memory. Here’s an example of keychain dump output.

sudo ./keychaindump

Keychain Dump

Note that when using the security binary to dump the passwords decrypted, several prompts will ask the user to allow this operation.

secuirty dump-trust-settings [-s] [-d] #List certificates
security list-keychains #List keychain dbs
security list-smartcards #List smartcards
security dump-keychain | grep -A 5 "keychain" | grep -v "version" #List keychains entries
security dump-keychain -d #Dump all the info, included secrets (the user will be asked for his password, even if root)


The kcpassword file is a file that holds the user’s login password, but only if the system owner has enabled automatic login. Therefore, the user will be automatically logged in without being asked for a password (which isn't very secure).

The password is stored in the file /etc/kcpassword xored with the key 0x7D 0x89 0x52 0x23 0xD2 0xBC 0xDD 0xEA 0xA3 0xB9 0x1F. If the users password is longer than the key, the key will be reused. This makes the password pretty easy to recover, for example using scripts like this one.

Library injection

Dylib Hijacking

As in Windows, in MacOS you can also hijack dylibs to make applications execute arbitrary code. However, the way MacOS applications load libraries is more restricted than in Windows. This implies that malware developers can still use this technique for stealth, but the probably to be able to abuse this to escalate privileges is much lower.

First of all, is more common to find that MacOS binaries indicates the full path to the libraries to load. And second, MacOS never search in the folders of the $PATH for libraries.

However, there are 2 types of dylib hijacking:

  • Missing weak linked libraries: This means that the application will try to load a library that doesn't exist configured with LC_LOAD_WEAK_DYLIB. Then, if an attacker places a dylib where it's expected it will be loaded.

    • The fact that the link is "weak" means that the application will continue running even if the library isn't found.

  • Configured with @rpath: The path to the library configured contains "@rpath" and it's configured with multiple LC_RPATH containing paths. Therefore, when loading the dylib, the loader is going to search (in order) through all the paths specified in the LC_RPATH configurations. If anyone is missing and an attacker can place a dylib there and it will be loaded.

The way to escalate privileges abusing this functionality would be in the rare case that an application being executed by root is looking for some library in some folder where the attacker has write permissions.

A nice scanner to find missing libraries in applications is Dylib Hijack Scanner or a CLI version. A nice report with technical details about this technique can be found here.


This is a colon separated list of dynamic libraries to load before the ones specified in the program. This lets you test new modules of existing dynamic shared libraries that are used in flat-namespace images by loading a temporary dynamic shared library with just the new modules. Note that this has no effect on images built a two-level namespace images using a dynamic shared library unless DYLD_FORCE_FLAT_NAMESPACE is also used.

This is like the LD_PRELOAD on Linux.

This technique may be also used as an ASEP technique as every application installed has a plist called "Info.plist" that allows for the assigning of environmental variables using a key called LSEnvironmental.

Since 2012 when OSX.FlashBack.B [22] abused this technique, Apple has drastically reduced the “power” of the DYLD_INSERT_LIBRARIES.

For example the dynamic loader (dyld) ignores the DYLD_INSERT_LIBRARIES environment variable in a wide range of cases, such as setuid and platform binaries. And, starting with macOS Catalina, only 3rd-party applications that are not compiled with the hardened runtime (which “protects the runtime integrity of software” [22]), or have an exception such as the entitlement) are susceptible to dylib insertions.

For more details on the security features afforded by the hardened runtime, see Apple’s documentation: “Hardened Runtime


In MacOS several folders executing scripts with certain frequency can be found in:

ls -lR /usr/lib/cron/tabs/ /private/var/at/jobs /etc/periodic/

There you can find the regular cron jobs, the at jobs (not very used) and the periodic jobs (mainly used for cleaning temporary files). The daily periodic jobs can be executed for example with: periodic daily.

File Extensions Apps

The following line can be useful to find the applications that can open files depending on the extension:

/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -dump | grep -E "path:|bindings:|name:"

Or use something like

You can also check the extensions supported by an application doing:

cd /Applications/
grep -A3 CFBundleTypeExtensions Info.plist | grep string

Risk Files Mac OS

The files /System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/System contains the risk associated to files depending on the file extension.

The possible categories include the following:

  • LSRiskCategorySafe: Totally safe; Safari will auto-open after download

  • LSRiskCategoryNeutral: No warning, but not auto-opened

  • LSRiskCategoryUnsafeExecutable: Triggers a warning “This file is an application...”

  • LSRiskCategoryMayContainUnsafeExecutable: This is for things like archives that contain an executable. It triggers a warning unless Safari can determine all the contents are safe or neutral.
