Conficker Update Part 3
According to http://forum.drweb.com/index.php?showtopic=277240 , Win32.HLLW.Shadow.based is a a variant of Conficker/downadup.
Symptom: Every available port from 1024-5000 is used to connect to various servers on destination port 445. Basically, the worm opens these connections to download and wait for malicious binaries.
The removal tools at http://www.bdtools.net/ does not detect this variant, and you have to use Dr.Web’s Cureit to detect and remove it. According to them, the recommended procedure is to install the following hotfixes:
* MS08-067
(http://www.microsoft.com/technet/security/bulletin/ms08-067.mspx);
* MS08-068
(http://www.microsoft.com/technet/security/bulletin/ms08-068.mspx);
* MS09-001
(http://www.microsoft.com/technet/security/bulletin/ms09-001.mspx).
And then run Cureit, a fully functional shareware app.
In case you’re reading this from an infected server, I’ve downloaded and included some of these files here (because if you’re infected, you won’t be able to access certain sites, drweb.com being one).
