 We have seen that many people *posting* do not have the best of intentions;
 I can assure you that there are lurkers on Nanog (surprise, surprise) who
 are not nearly as naive and well-intentioned as J. O. would hope. In fact,
 I know that there are subscribers from various print media, various on-line
 media, and certainly some stunningly unpleasant characters that I run into
 on other lists.

And after being /.ed several times, there are undoubtedly end-users,
small enterprises, non-network folks from networking companies, and
assorted other groups which don't fit the traditional network operator mold.
Oh, and sales people...

Incidentally, I'd dump that stock you just bought - the CEO of that

 'vuln'dev', and besides I wouldn't think that any
 one here would do something malicious with any idea
 that actually worked for the worse.

Assuming that everyone subscribed to the list has the best of intentions,
what about people that can scan the publicly accessible archives? Or even
the search engines that have nanog archives indexed? There's nothing wrong
with kicking ideas like this around with the intention of coming up with a
strategy on how to combat them, but perhaps a more discreet forum would be
appropriate?

I didn't get a chance to look at your idea very closely, but there are
interesting possibilities brought up.

Stunning innocence. I had to read this statement at least four times to be
sure that I was not mistaken. Then I examined the headers, and I wonder if
you (J. Oquendo) are being a bit disengenous. You may be well-meaning, but
I cannot believe that anyone believes such a thing.

There is no such thing as a discreet forum. If you mean by that, a few
people exchanging emails, then surely that is not a forum, not being
public. If it is publically accessible, and you aren't sure of precisely
every member that's on it, then it's NOT discreet. It may be obscure, but I
know plenty people who specialize in the obscure.

Those are hardly the persons you need worry about. There *is* no hacker
community. There may be pockets here and there, with people of varying
skills, and purposes, but there is no community. 

On the other hand, this is almost certainly not a topic for Nanog, even if
the word BGP does appear in the original post.

Sobigf + BGP

2003-08-23 Thread J. Oquendo

I was reading some PDF files on BGP along with
Routing TCP/IP v2, and I found myself pondering
what a nasty damn worm it would be if someone
were to do something using winpcap in conjucting
with the worm/virus, and I was a bit confused,
disturbed, lost. So I drew up a quick question
complete with ascii which can be viewed at
politrix.org/segment/brat.txt for those who get
a distorted diagram...

Apologies beforehand if this post seems a bit odd,
but I did not see anything similar to a networking
'vuln'dev', and besides I wouldn't think that any
one here would do something malicious with any idea
that actually worked for the worse.

-
brat.txt 

I was thinking about the recent polymorphic Sobigf worm/virus
and wondered about the following hypothetical scenario...

Sorry about this ASCIIgram, I didn't want to look for Visio
nor any other graphic program to do this in, strictly terms
to keep it gritty... So here goes.

Attacker scripts Sobigf variant with a virii/worm generator,
and uses pcap (packet capture) under Windows to have his
worm send out predefined packets. Let's say he created what
I call a 'BRAT' BGP Router Attack Tool. Now this tool isn't
something major it simply sends out two types of packets
aimed at routers running BGP.

They're both Notification Messages:

=
Packet 1 = BGP NM ERROR CODE 2 SUBCODE 2 |
Packer 2 = BGP NM ERROR CODE 6   |
=

Now we have the hosts' information:
www.targetednap.net (4 if's)
192.168.1.1 192.168.4.1 10.10.1.1 10.10.5.1

VIC's
nap.maefi.com   Link 1 nsp.maefee.com  Link 2
nap.maefo.com   Link 3 nsp.maefum.com  Link 4

  
Link 1 Link 2
\   /
  -
 | |
 | Targetednap.net |
 | |
  -
/   \
 Link 3Link 4

Script kiddiot sets up his worm/virii to send packets
as Targetednap to all VIC's as Targetednap via spoofing using
WinPCAP. Given the rate of connections that were mentioned
for SoBigf, what could happen say if route dampening were used
between the routers. Would penalties keep adding up making the
connection intolerable because of latency, would it ignore it.

Or what could happen say if worm was smart enough to send
NLRI's of something like $targetvalue=0

Wouldn't this knock off connections between BR's/ABR's, etc.
Are there any flags one can take to prevent this from occurring.
Keep in mind that packet creation is not difficult. My guess
would be, even if someone didn't get all fancy with the packets
being sent, a couple of million packets sent with say a:
ping -l 25000 $VIC as $TARGETEDNAP would be enough to cause
some massive latency, maybe even disconnect a backbone perhaps?

Anyone care to share links on security on this level if
any are available
