We will use Maltego CE to gather BGP autonomous system information:
- By right-clicking on the IP netblock, we can now obtain the BGP AS number assigned to this netblock by selecting Paterva CTAS | To AS number:
Maltego - Graph screen with www.example.com
- Next, we want to find the owner of the AS number in question. Right-click on the AS number and select All Transforms | To Company [Owner].
We will be continuing to use Maltego for further examples, so, either save your graph at this point so that you can come back to it, or continue on with other operations.
