Storm worm April Fool’s Day edition

So raw IPs as the URL. No major changes, but here are the specifics for this variant:

” Peerlist: C:WINDOWSaromis.config
” Installs as: C:WINDOWSaromis.exe
” As always, listens on a random UDP port, makes a lot of outbound connections, allows itself to the firewall via “netsh firewall set” and via the registry, uses w32tm to update its clock, and so on.
