Block all APNIC and RIPE assigned networks at the border and all of the sudden, hack attempts and CC fraud disappear.
And if I block the ARIN assigned networks, most of the spam I receive disappears. It's very effective.
If you block all APNIC, RIPE *and* ARIN blocks, together with some legacy stuff, most network abuse problems stop entirely. I have found traffic sourced from 127.0.0.1 to be generally clean though. -- Alex Bligh VP Core Network, Concentric Network Corporation (formerly GX Networks, Xara Networks)
