Sober Code Cracked

An anonymous reader writes "The algorithm used by the Sober worm to 'communicate' with its author has been cracked. According to F-Secure, it can now calculate the exact URLs the worm would check on a particular day. Mikko Hyppönen, chief research officer at F-Secure, explained that the virus author has not used a constant URL because authorities would easily be able to block it. From the article: "Sober has been using an algorithm to create pseudorandom URLs which will change based on dates. Ninety nine percent of the URLs simply don't exist...however, the virus author can precalculate the URL for any date, and when he wants to run something on all the infected machines, he just registers the right URL, uploads his program and BANG! It's run globally on hundreds of thousands of machines," Hyppönen said. Sober is expected to launch itself again on January 5, 2006."

      It all makes sense! Marilyn Manson writes the Sober worm, gets it to download a HTTP server and a copy of his latest album, then gets the PC to phone home every time it goes online, which issues an automatic DMCA takedown order on the PC that it came from! Ohh boy, wait till the boys at the RIAA get wind of this one... They'll be screaming "Why didn't we think of that!"

    Personally, I usually just chill while connected with ethereal running, then connect back to the PCs backdoored by the viruses that are trying to infect my honeypot on tcp/135. Then a simple netstat will show you an established tcp connection back to the IRC server the virus is using to announce itself to the author (not to mention about 500 connections SYN-SENT or ESTABLISHED to PCs being infected/probed, also a good source for other infected, backdoored PCs. You do know what is attacking you and what tcp backdoor it runs, right?) You can usually spot that connection, it has a high TCP destination port, whereas the normal vector port is 135/137/139. It's really sad to see thousands of PCs aleady announcing themselves to the author on that IRC channel as, "Hey come on over, I am running W2k|2XP. I am XP200453." And there is no one there to give me +OP privs!!! Batrastards!!! I could echo 'you are hacked please visit windowsupdate.com'> the startup folder all I want for days to each one of them to no avail... or echo ''you are a moron, too stupid to own a computer, put it back in the box and yadayadayada....

    I wonder what I would do with a beowulf cluster of networks of hacked (i.e. unpatched windows) PCs. probably echo the same message in the same fashion as above, yet, alas, I am seriously lacking in motivation and spare time. (q.q.v 4. Pr0F1T!!!)
