More about Worm:VBS/Tibni.A

This particular variant is closely connected with the suspicious search engine http://www.bahaty.com/red/g.php, because it is reported by Microsoft cyber-threat researchers to create the following files that may open your browser with this link on it:

→%desktop%\Internet Explorer.lnk
%desktop%\Opera.lnk
%desktop%\Mozilla Firefox.lnk
%desktop%\Safari.lnk
%desktop%\Google Chrome.lnk

More to it, than that, it places the very same shortcuts in the %APPDATA%\Microsoft\Internet Explorer\Quick Launch directory, otherwise known as Microsoft Quick Launch.

After that, the worm is reported to make the following files in these locations:

→D:\bin.doc ;D:\system\ bizo.mp3
D:\AUTOEXE\img.jpg
D:\Nouveau Dossier.lnk D:\NTDETE\Photo0.jpg
D:\boot\pict.jpg
D:\’username’\ Zain

This worm is also reported to copy these files from the malicious drive to other external drives connected to the computer:

img.jpg, bin.doc, pict.jpg, Photo0.jpg, bizo.mp3, Nouveau Dossier.lnk, Zain

More so, the threat creates a Start.lnk object in the startup folder that allows it to run when Windows runs. This shortcut is reported to run wscript.exe /e:VBScript.Encode D:\bin.doc which in its turn modifies these registry entries by creating values, like biotin in them:

→HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
C:\WINDOWS\system32\wscript.exe /e:VBScript.Encode D:\bin.doc

The file bin.doc is used with a very specific purpose: To load these files in the system:

→AUTOEXE, boot, NTDETE

The activity of this worm does not end with this, though. It is believed to use the domain ftp.bahaty.com to download the malicious file micropro.exe via the FTP protocol.
