Technical Details

Adware:W32/Gibmedia attempts to connect to remote websites, presumably to download advertising content. It also alters the search provider used by the Internet Explorer (IE) web browser.


When first executed, Gibmedia creates the following files:

  • C:\Program Files\Winsudate
  • C:\Program Files\Winsudate\gibcom.dll
  • C:\Program Files\Winsudate\gibidl.dll
  • C:\Program Files\Winsudate\gibsvc.exe
  • C:\Program Files\Winsudate\gibupt.exe
  • C:\Program Files\Winsudate\gibusr.exe

It then creates launch points for these files in the Windows Registry:

  • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run Data = "C:\Program Files\Winsudate\gibusr.exe"
  • HKEY_USERS\S-1-5-21-1390067357-1275210071-839522115-500\Software\Microsoft\Windows\CurrentVersion\Run Data = "C:\Program Files\Winsudate\gibusr.exe"


When run, Gibmedia will try to connect to the following websites:

  • https://www.renseignements-[...].fr/install

Adware:W32/Gibmedia will also connect to the following sites without the notice of the users:


At the time of writing, the first page Gibmedia connects to returns a 404 server error, while the second page shows a link to the file[...].exe, which is believed to be a Gibmedia component. These connections may be made without the user's knowledge and/or authorization.

Gibmedia also modifies the search provider used in by IE by adding the following registry keys:

HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\SearchScopes

Display Name = YouGoo

URL = q={searchTerms}


Display Name = Wibeez

URL = q={searchTerms}
