Repository of scrips to add AlienVault's OTX intel feed to zeek

The scripts works with a (free) API key from AlienVault's OTX feed. Obtain a key by signing up for the OTX service here: https://otx.alienvault.com/

The zeek-otx.py script can be run independently, or to install on a SecurityOnion 2 machine:

git clone https://github.com/SackOfHacks/zeek-otx.git

cd zeek-otx

chmod +x install-so2.sh

sudo ./install-so2.sh

After initial install it might take a few minutes for Zeek to start using the intel feed. You can monitor results with the following command:

tail -f /nsm/zeek/logs/current/intel.log

(example output for running a nslookup on "w0x.host"):
