Sober.Y reminder Posted by Jarkko @ 14:46 GMT

Just to remind you, Sober.Y update phase starts on 6th day. This means that all machines infected by Sober.Y try to download and execute code from certain addresses. If you want block these addresses at your firewall, here is the list again. The actual filename is left intentionally out from the addresses.

The most likely set of download URLs is:

people.freenet.de/zmnjgmomgbdz/
people.freenet.de/smtmeihf/
people.freenet.de/qisezhin/
people.freenet.de/fseqepagqfphv/
people.freenet.de/urfiqileuq/

home.arcor.de/dixqshv/
home.arcor.de/srvziadzvzr/
home.arcor.de/nhirmvtg/
home.arcor.de/jmqnqgijmng/


However, in some circumstances, Sober might try to access some of the following URLs:

home.arcor.de/oakmanympnw/
home.arcor.de/riggiymd/
home.arcor.de/jhjhgquqssq/


These additional addresses might be produced by the URL algorithm in certain rare conditions. We are not sure if this is the intention of the worm author, but it might be a good idea to block all of the above addresses.
