Troj/HideDial-E is a dialler-related Trojan.
Troj/HideDial-E drops and runs a dialler (detected by Sophos as Dial/Tibsys-A)
which attempts to connect to a premium-rate phone number for pornographic
material. The Trojan runs in the background and attempts to conceal the dialler
application by hiding windows that the dialler would usually display.
Troj/HideDial-E copies itself to the Windows system folder as TIBS3.EXE and
creates the following registry entry in order to run itself on system logon or
startup:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run
tibs3
<Windows system>\tibs3.exe
The dialler is dropped in the Windows system folder as _T.EXE.
The Trojan may also create or alter registry entries in the following location:
HKCU\Software\WebSiteViewer
The Trojan may drop and run a file TIBS3.BAT to delete the original file after
it is copied to and executed within the Windows system folder.
This IDE file also includes detection for:
Troj/Riler-F
