    Hey i found this website on that Sobig worm. Looks like a very smart feller just wasted his talent on this.


    Windows e-mail worm Sobig.F, which is currently the most widespread worm in the world, has created massive e-mail outages globally since it was found on Tuesday the 18th of August -- four days ago. The worm spreads itself via infected e-mail attachments in e-mails with a spoofed sender address. Total amount of infected e-mails seen in the Internet since this attack started is close to 100 million.

    However, the Sobig.F worm has a surprise attack in its sleeve. All the infected computers are entering a second phase today, on Friday the 22nd of August, 2003. These computers are using atom clocks to synchronize the activation to start exactly at the same time around the world: at 19:00:00 UTC (12:00 in San Francisco, 20:00 in London, 05:00 on Saturday in Sydney).

    On this moment, the worm starts to connect to machines found from an encrypted list hidden in the virus body. The list contains the address of 20 computers located in USA, Canada and South Korea.

    "These 20 machines seem to be typical home PCs, connected to the Internet with always-on DSL connections," says Mikko Hypponen, Director of Anti-Virus Research at F-Secure. "Most likely the party behind Sobig.F has broken into these computers and they are now being misused to be part of this attack."

    The worm connects to one of these 20 servers and authenticates itself with a secret 8-byte code. The servers respond with a web address. Infected machines download a program from this address -- and run it. At this moment it is completely unknown what this mystery program will do.

    F-Secure has been able to break into this system and crack the encryption, but currently the web address sent by the servers doesn't go anywhere. "The developers of the virus know that we could download the program beforehand, analyse it and come up with countermeasures," says Hypponen. "So apparently their plan is to change the web address to point to the correct address or addresses just seconds before the deadline. By the time we get a copy of the file, the infected computers have already downloaded and run it."

    Right now, nobody knows what this program does. It could do damage, like deleting files or unleash network attacks. Earlier versions of Sobig have executed similar but simpler routines. With Sobig.E, the worm downloaded a program which removed the virus itself (to hide its tracks), and then started to steal users network and web passwords. After this the worm installed a hidden email proxy, which has been used by various spammers to send their bulk commercial emails through these machines without the owners of the computers knowing anything about it. Sobig.F might do something similar -- but we won't know until 19:00 UTC today.

    "As soon as we were able to crack the encryption used by the worm to hide the list of the 20 machines, we've been trying to close them down," explains Mikko Hypponen. F-Secure has been working with officials, authorities and various CERT organizations to disconnect these machines from the Internet. "Unfortunately, the writers of this virus have been waiting for this move too." These 20 machines are chosen from the networks of different operators, making it quite likely that there won't be enough time to take them all down by 19:00 UTC. Even if just one stays up, it will be enough for the worm.

    The advanced techniques used by the worm make it quite obvious it's not written by a typical teenage virus writer. The fact that previous Sobig variants we're used by spammers on a large scale adds an element of financial gain. Who's behind all this? "Looks like organized crime to me," comments Mikko Hypponen.

    F-Secure is monitoring the Sobig.F developments through the night on Friday the 22nd. Updates will be posted to Sobig.F's virus description at http://www.f-secure.com/v-descs/sobig_f.shtml

    19.00 was almost 3 hours ago

    you know what else is kinda funny....
    not sure if anyone pointed this out or not
    The 'From:' field is filled with an address found from the infected system.
    If no address is found, it will use "admin@internet.com"
    ummm, jupiter media owns internet.com coincidence?
