Auxiliary modules define some procedures that need to be executed in parallel to every single analysis process. All auxiliary modules should be placed under the modules/auxiliary/ directory.
The skeleton of a module would look something like this:
1 2 3 4 5 6 7 8 9 from lib.cuckoo.common.abstracts import Auxiliary class MyAuxiliary(Auxiliary): def start(self): # Do something. def stop(self): # Stop the execution.
start() will be executed before starting the analysis machine and effectively
executing the submitted malicious file, while the
stop() function will be launched at the
very end of the analysis process, before launching the processing and reporting procedures.
For example, an auxiliary module provided by default in Cuckoo is called sniffer.py and takes care of executing tcpdump in order to dump the generated network traffic.
