For some background on how legal it is to obtain (your own) data dumps, Leonard Bailey (US DOJ) did a great talk at RSA Conference 2020 (I attended this talk in person) on "Human Dimensions of Active Defense": https://www.rsaconference.com/usa/us-2020/agenda/human-dimensions-of-active-defense https://www.rsaconference.com/usa/us-2020/agenda/human-dimen... His talk covers a lot of active defense techniques, and goes over some legal points in this area.
