W32/Pushbot-B is a worm for the Windows platform.

W32/Pushbot-B spreads to removeable drives.

When run W32/Pushbot-B copies itself to:

<removeable device>\driver\usb\<random name>.exe
<Windows>\rndll.exe

and creates an autorun.inf file in the root of the removeable drive in an attempt to run itself automatically when the drive is loaded (detected separately as W32/SdBot-DNU).

New files and folders on the removeable drive will have the hidden, system and read-only attributes set.

The following registry entries are created to run rndll.exe on startup:

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
Firevall Administrating
rndll.exe

HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Terminal Server\Install\Software\Microsoft\Windows\CurrentVersion\Run
Firevall Administrating
rndll.exe

The following registry entry is set, affecting internet security:

HKLM\SYSTEM\CurrentControlSet\Services\SharedAccess\Parameters\FirewallPolicy\StandardProfile\AuthorizedApplications\List
<Current Folder>\gdfsgdf.exe
<Current Folder>\gdfsgdf.exe:*:Enabled:Firevall Administrating
