NANOG: Look, the people posting here who are trashing Intercage are pure security analysts -- they know and understand the evil that is Intercage. STOP TRYING TO ASSIST INTERCAGE -- you are effectively aiding and abetting the enemy. Intercage/Atrivo hosts the malware c&c botnets that DDoS your systems and networks. Intercage/Atrivo hosts the spyware that compromises your users' passwords. Intercage/Atrivo hosts the adware that slows your customers' machines. Don't take my word for it, DO YOUR OWN RESEARCH: http://www.google.com/search?hl=en&q=intercage+malware You don't get called the ***American RBN*** for hosting a couple bad machines. They have and will continue to host much of the malware pumped out of America. THEY ARE NOT YOUR COMRADES. These people represent the most HIGHLY ORGANZIED CRIME you will ever come across. Most people were afraid to speak out against them until this recent ground swell. This is the MALWARE CARTEL. GET THE PICTURE? Many links have been posted here that prove this already -- instead of asking what customers they cut off, let them show WHAT CUSTOMERS ARE LEGIT-- because there are NONE.
I would suggest a different Step 1. Instead of killing power, simply isolate the affected machine. This might be as simple as putting up a firewall rule or two, if it is simply sending outgoing SMTP spam, or it's probably easiest (depending on the network gear of course) to just put the lan port into an isolated VLAN. It's not the 100% solution (some badness rm's itself once it loses connectivity to the internets) but it'd make things simpler for the client/LEA when they need to figure out what happened.
