Welcome to avatar², the target orchestration framework with focus on dynamic
analysis of embedded devices' firmware!Avatar² is developed and maintained by [Eurecom's S3 Group](http://www.s3.eurecom.fr/).
# Building
Building avatar² is easy!
First, make sure that all the dependencies are present:
```
sudo apt-get install python-pip python-setuptools python-dev cmake
```Afterwards, use python-pip to install avatar2:
```
pip install avatar2
```Now you are all ready to go. Additionally, if you want to install specific
target entpoints, please run the avatar2-installer, which tries to fetch and
install the endpoints automatically.```
python -m avatar2.installer
```### Building with Docker
A Dockerfile is present which build by default avatar² with QEmu and PANDA target endpoints:
```
$ docker build -t avatar2 .
$ docker run --rm avatar2 python3 -c "import avatar2"
```Alternately, you can use `generate_dockerfile.py` to build a docker image with only the target endpoints your need:
```
$ python3 generate_dockerfile.py --endpoint_list avatar-qemu --qemu_targets arm-softmmu
$ docker build -t avatar2 .
```### Building manually
Avatar² can also be built manually.
The following three commands are enough to install the core.
```
$ git clone https://github.com/avatartwo/avatar2.git
$ cd avatar2
$ sudo python setup.py install
```
Afterwards, the different target endpoints can be built, such as QEmu or PANDA.
For doing so, we are providing build-scripts for Ubuntu 20.04 - while other
distributions are not officially supported (yet), the scripts are known to
work with slight modifications on other distributions as well.
```
$ cd targets
$ ./build_*.sh
```**Please Note:** These scripts add the restricted repository to
`/etc/apt/sources.list` for fetching the dependencies. If you are not comfortable
with this, please consider building avatar² in a VM/Container or install the
dependencies manually and adjust the scripts.# Getting started
For discovering the power of avatar² and getting a feeling of its usage,
we recommend highly checking out the
[handbook](https://github.com/avatartwo/avatar2/tree/master/handbook) here on
github.
Additionally, a documentation of the API is provided
[here](https://avatartwo.github.io/avatar2-docs/) and some exemplary
avatar²-scripts can be found
[here](https://github.com/avatartwo/avatar2-examples).
Additionally, another good way to get started with avatar² is to read the official
[avatar² paper](http://www.s3.eurecom.fr/docs/bar18_muench.pdf) or to watch the
[34c3-talk](https://media.ccc.de/v/34c3-9195-avatar).For further support or follow-up questions, feel free to send a mail to
avatar2 [at] lists.eurecom.fr, our public mailing list, on which you can
subscribe [here](https://lists.eurecom.fr/sympa/subscribe/avatar2).Additionally, you can find us on [slack](https://avatartwo.slack.com/) for more
vivid means of communication - if you want an invite, just send us a mail!# Publications
