Seems like it this is pretty ineffective. The group already moved subnets once, they will likely do this again, all Cisco/L3 have done is slow them down a bit.

Looks like the two /23's they mention are now being advertised as /24's, and I'm also not sure why cisco published the ssh attack dictionary. It seems to me that this is something that if they want to do, they should be working with entire service provider community, not just one provider.
