largescale internet blackout in indian broadband services
by Suresh Ramasubramanian 16 Sep '04

16 Sep '04

These people provide DSL, leased lines as well as last mile connectivity for a whole lot of Indian broadband providers, and they also run a rather popular cdma wireless phone and gsm cellphone service. srs ------------- http://www.hindu.com/2004/09/16/stories/2004091611870300.htm Airtel and Touchtel services were shut down in Chennai at about 8.45pm IST last night due to a fire in their NOC.

Excessive Internet Traffic
by Robert Scott 15 Sep '04

15 Sep '04

The University of Central Florida has seen a sudden jump in tcp 445 denies. It began a little after 9:00 AM EDST. New Worm? I am denying about 32 thousand packets per second. IP Cache flow show them well spread over a wide range of addresses, targeted at what apeears to be a random sample of my class B. The ACL on our border router is taking 21 million denies every 10 minutes. 60 deny tcp any any eq 445 (346740094 matches) The packets are small, since I am seeing a large nuber of packets, but the bit count is low. 30 second input rate 72679000 bits/sec, 41033 packets/sec 30 second output rate 29208000 bits/sec, 7687 packets/sec Input bits per second are a little above normal, but the packet count would normally be under 10000 not 41000.

This is likely a variant of what I forsee to become the "next big pain", a variant of sdbot, of which McAfee claims there are 4000 variants. I've had to deal with quite a few (and climbing) numbers of infected users of this pain. We use a Packeteer and have listed comps sending outbound 445 garbage and I've found that almost all have been infected by one of the versions of this particular worm. Which of the 4000 versions it is eludes me. This is what I've seen so far. If you look at the machine sending the traffic out, you're likely going to see a smorgasbord of junk in c:\WINDOWS\system32 ... If you view the folder as a list, then sort by date, you're likely to find a huge amount of executables on the machine. As well as logs, TFTP information etc. You can try opening up task manager but it will be useless... So being I'm already getting more and more familiar with this pest, here is what it does: ///// Public Sub AVkiller() On Error Resume Next 'prefix Dim AVmonz As Variant ' varz: Dim Cur As String '---||--- Dim i '---||--- AVmonz = Array("", "AVP Monitor", _ "AntiVir", _ "Vshwin", _ "F-STOPW", _ "F-Secure", _ "vettray", _ "InoculateIT", _ "Norman Virus Control", _ "navpw32", _ "Norton AntiVirus", _ "Iomon98", _ "AVG", _ "NOD32", _ "Dr.Web", _ "Amon", _ "Trend PC-cillin", _ "File Monitor", _ "Registry Monitor", _ "Registry Editor", _ "Task Manager") 'Declaration of AV shitz For i = 1 To 20 'kill'em all... Cur = AVmonz(i) 'convert to string Call TerminateTask(Cur) 'terminate task ;) Next i End Sub ///// Nifty huh? The virus installs itself in the registry under odd names associated with Microsoft for example, so far I've seen it installed in a Run, Run Once folder called Windows Security, Windows Update, etc. There is no removal tool for this and being it renders many virus software useless, you can either have a user reinstall Windows, or you can search the machine for instances of things created on the same date as the serv32.exe program, or one of the other ones it installs. Now... The worm seems to perhaps download 4 other programs I've always seen running in conjuction with it. wupd.exe which masquerades as "Windows Update" ftpd.exe which opens up an ftp server on the infected machine and goes around re-downloaded various other viruses and worms on the infected machine, and one which I believe tries to infect other machines perhaps a-la Blaster worm. Another program opens seems to randomly name viruses and worms once downloaded so for example, wupd.exe will probably turn into something like A032424.exe the next time around, and so on and so forth. So far I've seen students where I am either getting this via file sharing, one program which has been sticking out like a sore thumb is something called ARES. It could be also spreading, again, through some of the katrillion MS vulnerabilies and perhaps even the newly discovered "Drag and Drop" vulnerability. Drag and Drop vulnerabilities http://secunia.com/advisories/12321/ So now there is also the "bling.exe" issue which is the worm that "sniffs out passwords" (http://isc.sans.org/diary.php?date=2004-09-12) this one opens up an irc connection to dump out data to some channel. I will eventually (when I have some time) hexedit some of these to see what it does and perhaps repost more information.

We recently purchased Device Authority primarily for its auditing and compliance monitoring, but also for the ease with which we can push out mass changes to devices. It's honestly cooler than sliced bread. The downside to these applications is the price. Ouch. Regardless, now that I have Device Authority, I sure as heck would not give it back! John --

Open-Source Network Management Tools
by Claydon, Tom 15 Sep '04

15 Sep '04

I'm looking for open-source alternatives for network management, such as Nagios or Big Brother. We are currently using WhatsUp Gold, and would like to move to something more flexible (and not running on a Windows platform). Something that has email/paging capabilities, and can process SNMP traps would be a plus for us as well. Recommendations? Thanks.

We have been using JFFNMS (http://www.jffnms.org) for the last 2 years and works just great. You can monitor almost anything you'd like to via SNMP (we currently use it to graph Traffic, Drops, Input Errors, RTT, Packet Loss, CPU, Memory, Temperature, TCP Connections, BGP, etc). And has email/paging capabilities. Try it out and let me know.

RE: Email Complexes

Fantastic. Call the providers, purchase an account and let's be done with this thread. -----Original Message----- From: Hosman, Ross [mailto:Ross.Hosman@chartercom.com] Sent: Tuesday, September 14, 2004 4:40 PM To: 'Mark Foster'; Hannigan, Martin Cc: nanog(a)merit.edu Subject: RE: Email Complexes Let me see if I can explain your entire email. Ensuring that email flows freely between our mail complex and other top mail provider complexes is a support issue correct. Actually setting up the system to monitor and to ensure the support people get the data they need is operations/engineering. We like automating a lot of our procedures as our mail complex isn't staffed 24/7. Right now we have a script that monitors incoming mail sent from probes across the us. It monitors how long it takes the email to first hit the IronPort's, then how long it takes to hit the Brightmail, then how long it takes to hit the MTA's. Our script uses pop3 to grab the email and parse the headers we send from the probes (or in this case from the complex to the pop accounts). Yes I do realize some are webmail (AOL, MSN, Gmail), but even a lot of the webmail providers do have pop3 servers. Our intent here is not not only verify that the email got there but that it got there in a reasonable time (lets face it email is becoming a more imporant part of life/business today). As fair as teaching the support guys to go look at the mail queue, would you honestly want them to be doing that? We have over 65 mail machines and should I trust them with checking them every 10 min? Since we are not staffed 24/7 what happeneds if we have all gone home? The way we have it setup if the mail never reaches the complex tier-1 gets a page, 15 minutes later if the problem still isn't solved tier-2 gets a page. I believe automating the system rather then trutsing a staff member to check it and to pray that it dosen't break during the night is a much better way of doing it. -----Original Message----- From: owner-nanog(a)merit.edu [mailto:owner-nanog@merit.edu]On Behalf Of Mark Foster Sent: Tuesday, September 14, 2004 4:04 PM To: Hannigan, Martin Cc: nanog(a)merit.edu Subject: RE: Email Complexes I find it interesting that you'd like pop3 access to a bunch of listed *webmail* providers. Who provide access via the web - NOT pop3. I also agree with the below statement - your mail queues themselves will provide far more accurate information. The issue of 'successful mail delivery' would be a support issue, not an operations issue, as long as you as an operations staffer can verify that your mailserver is not holding the mail for undue periods. (Mail doesnt have a delivery SLA in general, after all.) And if your support staff need offsite mail accounts to verify delivery delay times, they should be able to purchase them or otherwise obtain them, and keep a database of mail account access details that they can use *on demand*. This would of course entail them becoming customers and footing the regular monthly bill, or whatever. In every ISP i've ever worked for, all we've needed to do is verify that we're delivering the mail to the advertised MX in a timely fashion, and our responsibility ends at that point. Outside of the usual responsibilities of a good ISP - like providing responsive abuse/security staff, like providing a valid abuse@ contact :-) This would be one of the primary reasons your mail doesn't get accepted, and prevention is better than cure... So in all honesty - if your company wants to extend its monitoring-ability outside of its own network to those of other providers, it should do so in the 'usual fashion' - sign up. How is this something that yourself as an operations employee got involved in anyway, as it strikes me as a support issue? - Mark.
