Happy Sunday nanogers...
I was doing some follow up reading on the "js.scob.trojan", the latest "hole big enough to drive a truck through" exploit for Internet Explorer.
On the the things the article mentioned is that ISP/NSPs are shutting off access to the web site in russia where the malware is being downloaded from.
Now we've done this in the past when a known target of a DDOS was upcoming or a known website hosted part of a malware package, and it is fairly effective in stopping the problems.
So what I was curious about is would there be interest in a BGP feed (like the DNSBLs used to be) to null route known malicious sites like that?
Obviously, both operational guidelines, and trust of the operator would have to be established, but I was thinking it might be useful for a few purposes:
1> IP addresses of well known sources of malicious code (like in the example above) 2> DDOS mitigation (ISP/NSP can request a null route of a prefix which will save the "Internet at large" as well as the NSP from the traffic flood 3> etc
Since the purpose of this list would be to identify and mitigate large scale threats, things like spammers, etc would be outside of it's charter.
If anyone things this is a good (or bad) idea, please let me know. Obviously it's not fully cooked yet, but I wanted to throw it out there.
