Troj/HideDial-B is a Trojan dialler application.
Troj/HideDial-B attempts to download a third-party dialler application to C:\MISB.EXE. The Trojan then runs the dialler, but attempts to hide windows normally displayed by the dialler in order to conceal this.
The Trojan randomly chooses one of three different URLs to download from. At the present time, all of these URLs point to files detected as Dial/Tibsys-A.
When first run, the Trojan copies itself to the Windows folder as IBS.EXE and creates the following registry entry in order to run itself on system startup:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\Explorer\Run
Ibs
<windows>\ibs.exe
