At the time of writing, Sophos has received a small number of reports of this Trojan from the wild. Information about Troj/HideDial-E can be found at: http://www.sophos.com/virusinfo/analyses/trojhidediale.html 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.
