This tool can be used to automatically build an ordered set of attack stages with MITRE ATT&CK techniques executed during each stage.
The output is a set of attack stages that show all possible techniques that an adversary might execute during each stage.
To decide when the different techniques are to be found in such a set, promises are used as access tokens for execution of techniques. Each technique defines the set of promises required to execute it (think pre-conditions) and the set of promises it provides upon execution (think post-conditions).
Install using pip:
pip install aepYou will also need to clone the aep-data repository, which contains a starting point witch example data:
git clone https://github.com/mnemonic-no/aep-dataIf you have checked out the aep-data repository you can run these commands in that repository, since you need access to default dat files.
aep-generate is where you should start and the other tools are more useful if you start making changes to the
data itself.
$ aep-generate --end-condition objective_exfiltration --include-techniques T1021,T1046,T1583 --technique-bundle incident/UNC2452-Solorigate.json --show-promises
Removed 4 NOP techniques: ['T1036', 'T1036.004', 'T1036.005', 'T1083']
