CME-24 (BlackWorm) Users' FAQ
by Gadi Evron 30 Jan '06

30 Jan '06

This FAQ was authored by members of the TISF BlackWorm task force (specifically the MWP / DA groups and the SANS ISC handlers). The purpose is both to provide with a resource for concerned users and network administrators, as well as to be a level-headed myth-free source on the subject. There seems to be excessive media hype as well as some "end-of-the-world" type predictions. The end of the world is not coming and most of us will still be here after February 3rd, but this is a serious issue for those who *are* infected and we didn't manage to get to. The FAQ can be found at: http://isc.sans.org/blackworm http://blogs.securiteam.org -- "300,000 infected users worldwide is not a terribly large amount when compared to previous worms like Sober or Mydoom. However, with this worm it isn't the quantity of infected users, it is the destructive payload which is most concerning." -- Joe Stewart, LURHQ (http://www.lurhq.com/blackworm-stats.html) Gadi.

>the scheme that josh karlin has been advocating in pretty good bgp >involved only supressing a doubtful announcement when you have a >better, more trusted announcement. Not a doubtful announcement, a novel announcement. Not a better announcement, a more usual announcement. The trust part, like beauty, is in the eye of the beholder. Don't get me wrong - I think basing decision on some "trusted" summary of historical behavior is going to be important, unless and until we get some approach that gives a more deterministic answer. But I do believe that we need to consider carefully how this will play with dynamic, particularly unplanned, changes in who is announcing what. If there turn out to be cases where dynamic, particularly unplanned, changes get rejected by this technique in favor of stale data, then there should be consideration given to how to amend the scheme to prevent that or suggest operational practices to get around it. --Sandy

I never realized so many trains derailed until my Internet kept going out
by Sean Donelan 29 Jan '06

29 Jan '06

http://www.thedenverchannel.com/technology/6490915/detail.html It was the third multi-day outage experienced by Comcast Western Slope customers. The two previous also came as a result of train derailments. One Aspen Comcast customer told the Aspen Times that he learned a lot about train derailments as result of his service interruptions. "I never realized so many trains derailed until my Internet kept going out," said Michael McVoy.

This is great for the planned changes, but real-time changes to respond to Internet dynamics won't work well with such delays. If you are multi-homed to provide a backup, you would like for it to respond more quickly than 4-72 hours, I'll bet. So if you have PI space but not your own AS, your backup route would look like a novel origination, but you sure wouldn't want it delayed. How common are such cases? Should the solutions cover them also? Should there be special procedures to deal with special cases? Etc. --Sandy

Wifi SIP WPA/PSK Support
by Mike Leber 27 Jan '06

27 Jan '06

I'm working on finding a Wifi SIP phone that supports WPA/PSK that we can recommended to VOIP clients. As everybody knows, currently most Wifi SIP phones support WEP which is demonstrably insecure. For banking and financial customers, or companies that are given passwords or credit cards over the phone, this is a serious security issue. We recently bought a Hitachi-Cable Wireless IPC-5000 WiFi SIP Phone from voipsupply.com after finding some web pages that said that phone supported WPA (the pages were in German), yet once we got the phone all it supported was WEP even after updating the firmware to the latest version using the website mentioned in the documentation that came with the phone. I've had a few people say that there was some sort of conspiracy to keep US citizens from using secure phones, however I found that laughable because the potential risk of terrorist or criminal interception from having all Wifi telephone conversations involving credit cards (let alone social security numbers, bank account numbers, passwords, what have you) in the clear would create an attack vector so large as to exceed all other possible attack vectors... I mean why work on cracking anything when you can just listen to everybody in the clear (well virtually in the clear with WEP). So, back in reality, could anybody in the US that bought their Wifi SIP phone in the US share a success story at getting Wifi SIP setup with WPA/PSK? What model of phone did you buy? Where did you get it? Did you have to upgrade it to any special version of firmware or what?
