Getcher hot streams while they last ... jmoffitt writes: "In his post to the Vorbis list, Ciaran announced that the Ogg Vorbis BBC streams of Radio 1 and Radio 4 that we've enjoyed since early November would go offline as the test is ending. Everyone is encouraged to send their encouragement for these streams to continue to webweaver@bbc.co.uk. Also, as a special treat, the Radio 4 Ogg stream has been extended a week - just enough for all to catch the first episode of Lord of the Rings on Saturday at 1430 GMT."

While MS may see it as good news, I think the fact that the hole is coming back to public attention just blackens the eye a little more for them. It will be interesting to see future ramifications of the government getting involved in these issues, too..." It can't look good when your company's software is called into question by some of your largest customers.
Nope, still don't see any. Niels Provos writes: "I just updated http://www.citi.umich.edu/u/provos/stego/usenet.php to reflect the final results from our search of hidden messages in USENET images. We did not find a single hidden message.
I also released a new version of stegdetect.
The disconcert cluster that we used for the dictionary attack contained more than two-hundred workstations, mostly from CAEN (that is the computer aided engineering network at UMich). The peak performance is comparable to 72 1200 MHz Pentium III machines :-) ...

Subject: Stegdetect 0.4 released and results from USENET search available
Date: Fri, 21 Dec 2001 12:16:14 -0500
Sender: provos@citi.umich.eduI just released Stegdetect 0.4. It contains the following changes:
- Improved detection accuracy for JSteg and JPhide.
- JPEG Header Analysis reduces false positives.
- JPEG Header Analysis provides rudimentary detection of F5.
- Stegbreak uses the file magic utility to improve dictionary
attack against OutGuess 0.13b.You can download the UNIX source code or windows binary from

The results from analyzing one million images from the Internet Archive's USENET archive are available at http://www.citi.umich.edu/u/provos/stego/usenet.php.
[...]
After scanning two million images from eBay without finding any hidden messages, we extended the scope of our analysis.
This page provides details about the analysis of one million images from the Internet Archive's USENET archive.
Processing the one million images with stegdetect results in about 20,000 suspicious images. We launched a dictionary attack on the JSteg and JPHide positive images. The dictionary has a size of 1,800,000 words and phrases. The disconcert cluster used to distribute the dictionary attack has a peak performance of roughly 87 GFLOPS. However, we have not found a single hidden message. [...]Comments and feedback are welcome. We have an FAQ at http://www.citi.umich.edu/u/provos/stego/faq.html"

I admit that I haven't studied the details of the exploit, but you're implying that spoofing a malicious packet or packets won't work?
Sure, they shut off the easy way to launch an attack, but I can still send that same message from another host, can't I?
You have violated Robot's Rules of Order and will be asked to leave the future immediately.
1) Internet firewall protects you from unicast attacks, but not multicast.
2) UPnP service is not the one with the vulnerability. It's the SSDP Discovery Service. It's also a manual startup, but it's started after boot on my box and every other xp box I've ever looked at (OK that's only about 5).
grc.com has some more info on how the FBI messed up ... again.
Note to moderators: the following has to do with Windows XP (SatanOS 5.1), so don't let that influence your moderation.
PLEASE NOTE: There is a great deal of confusion being caused by Microsoft's non-obvious naming of the two UPnP services. This situation is exacerbated by the FBI's NIPC web site, which has unfortunately posted wrong information over the holidays. People are led to believe that disabling the service named "Universal Plug and Play Device Host" disables the UPnP system. But it does not. That service is not even running by default. The correct action is to STOP then DISABLE the service named "SSDP Discovery Service".
You can demonstrate this for yourself by issuing the command "netstat -an" at a command prompt. While the SSDP Discovery service is running, Netstat will show that TCP port 5000 is in the listening state and UDP port 1900 is accepting inbound datagrams. After the SSDP Discovery Service has been stopped those Netstat lines will disappear.
I dont think either of you quite get it, although the two of you might have no trouble listening to 128kbps streams, there are _millions_ still on dialup... both of those streams will work fine on a dialup link but if i had to choose the lesser of two evils I'd pick ogg anyday.
as for higher bit rates I suggest you play around a bit with it... _some_ have said nominal 128kbps ogg is better than 160K lame encodings...
