Overview

Summary:

IEAccess is an ActiveX control used to download and install premium-rate dialers, primarily for porn sites.

Alias:

Dialer.LI [Panda], eGroup, TrojanDownloader.Win32.Wintrim.bg [Kaspersky]

Category:

Dialer: Software that dials a phone number. Some dialers connect to local Internet Service Providers and are beneficial as configured. Others connect to toll numbers without user awareness or permission.

Downloader: A program designed to retrieve and install additional files, when run. Most will be configured to retrieve from a designated web or FTP site.

  • IEAccess/HTMLAccess
  • IEAccess/HTMLDialer

    Date of Origin:

    Variants from October, 2002 to May, 2003

    Distribution

    Distribution:

    Installed by ActiveX drive-by-download by porn-related pages from nocreditcard.net and sex-explorer.com, which may be opened or redirected to by pop-up advertising.

    May be installed automatically, without prompting, on Internet Explorer versions earlier than IE6 Service Pack 1, thanks to a security hole. The installer pages exploit this to run an EXE which adds 'Electronic Group' to the list of trusted publishers whose software IE will install automatically without asking.

    Electronic Group distributes other dialers as well.

    Prevalence:

  • IEAccess: 4.4%
  • More Info

    Clot Factor:

  • IEAccess: 7
  • The "Clot Factor" is a measure of how much a pest "gums up" a machine by adding registry entries, files, and directories. As more objects are placed in a machine, manual removal becomes more difficult and more error-prone.

    Growth:

  • IEAccess: Insufficient data to report growth
  • Operation

    Advertising:

    No.

    Storage Required:

  • IEAccess: at least 213 KB
  • Risks

    Privacy Issues:

    No.

    Security Issues:

    IEAccess adds its manufactures to Windows's Trusted Publishers list. This means any web page can ensure any software signed by Electronic Group gets installed automatically when you visit it.

    It is also suspected that it may be possible to use the IEAccess ActiveX control on any web page to cause arbitrary unsigned code to be executed.

    Stability Issues:

    None known.

    Detection and Removal

    Manual Removal:

    From 'Downloaded Program Files' in the Windows folder, right-click the 'IEDial class' entry and remove it. This does not actually get rid of the software, so open a DOS command prompt window (from Start->Programs->Accessories) and enter the following command, for Windows 95/98/Me:

    "%WinDir%\System\regsvr32.exe" /u "%WinDir%\System\IEAccess2.dll"
    Or, for Windows NT/2000/XP:

    regsvr32 /u "%WinDir%\System32\IEAccess2.dll"
    You can now delete the 'IEAccess2.dll' file in the Windows System[32] folder. Next open the registry (Start->Run->regedit) and delete the key 'HKEY_CURRENT_USER\Software\egroup'.

    Finally, remove Electronic Group from your Trusted Publishers list. To do this, open the registry key HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\WinTrust\Trust Providers\Software Publishing\Trust Database\0 and delete the entry with the value 'ELECTRONIC GROUP'. (It's probably a good idea to keep this key completely empty.)

    You can also go to HKEY_CURRENT_USER\Software\Microsoft\SystemCertificates\TrustedPublisher\Certificates and delete Electronic Group's key. It should begin '08F573...'.

    IEAccess may have downloaded one or more unwanted diallers. Sometimes these may appear in an 'eGroup' folder in the Windows folder, as well as entries the more usual Program Files folder. Check and delete any diallers you find.

    Remove AutoRun Reference:

    Go To the key HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run.
    If you find the value HKEY_CURRENT_USER\software\microsoft\windows\currentversion\run\livesrv, delete it and reboot the machine immediately.
    If you find the value HKEY_USERS\s-1-5-21-1085031214-484061587-839522115-500\software\microsoft\windows\currentversion\run\livesrv, delete it and reboot the machine immediately.
