Death of the Internet, Film at 11

Not trolling in the least. I'm genuinely trying my best to help the greater community. 

Agreed on ShadowServer. I get their reports and I recommend others do the same. 

Oh, okay, I responded to someone that said: 

network operator who can do so, please raise your hand if you have 
*recently* scanned you own network and if you can -honestly- attest 
that you have taken all necessary steps to insure that none of the 
numerous specific types of CCVT thingies that Krebs and others identified 
weeks or months ago as being fundamentally insecure can emit a single 
packet out onto the public Internet. 

That's the direction I was heading. How can I as a network operator seek out and eliminate the sources of these attacks?

Not sure if you're trolling now, apologies if what I wrote 
wasn't clear. 

If you did want to find them before they attack then you could 
scan for them, the miscreants already did and easily found them. 

For some attack vectors there are services that are doing it 
for you, see the excellent

Did you read my whole mail? The suggestion is people who get attacked 
tell the ISPs of the devices doing the attacking

I was not suggesting you try and guess, I was suggesting you be given 
data from actual attacks.
