More Information

Troj/Goldun-R is a password stealing Trojan that steals bank details and sends
them to a remote site.

Troj/Goldun-R is comprised of a dropper file with the filename pin.exe that
creates MSplg7.dll and estsprt.sys files in the Windows system folder. Sophos's anti-virus products detect estsprt.sys as Troj/Haxdor-Gen.

In order to run automatically each time a user logs on, Troj/Goldun-R sets the following registry entries:

HKLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon\Notify\F8adsl\
DllName
